According to the CRS website, “The Controlled Release Society T. Nagai Postdoctoral Research Achievement Award has been established to recognize an individual postdoctoral candidate who has recently completed outstanding postdoctoral research in controlled release science and technology, and the postdoc’s advisor who played an integral role in those achievements.”
Mitchell and his postdoctoral advisor at MIT, Robert Langer, will receive the award at the 2019 CRS annual meeting this July in Valencia, Spain.
The sole recipient of this award, Mitchell was recognized for his work on engineering controlled release technologies for cancer gene therapy and immunotherapy. Mitchell focuses on improving the way drugs are delivered within the body by combining approaches from engineering, biology, machine learning, and data science to better target diseased cells. Mitchell’s work helps to lay the foundation for a new class of therapeutic strategies against hematologic cancers such as multiple myeloma and leukemia.
The annual International Genetically Engineered Machine (iGEM) competition challenges students to expand the field of synthetic biology to solve tangible problems. While most iGEM projects involve imbuing microorganisms with useful new traits and adding them to a global toolkit, Penn Engineering students took a unique approach to the iGEM challenge by creating an open-source blueprint for a mechanical instrument that could make biological research more accessible.
Penn Bioengineering undergraduate Andrew Clark and recent graduates Karol Szymula, now a research assistant in Penn’s Complex Systems Lab, and Michael Patterson, now the lab engineer for Penn Bioengineering’s Instructional Laboratories, contributed to the project that originated through the 2017 iGEM challenge. Graduate student Michael Magaraci, who started Penn’s iGEM program as an undergraduate, and Sevile Mannickarottu, director of Instructional Laboratories, also participated. Brian Chow, Assistant Professor in Bioengineering at Penn, who helped create the iGEM competition when he was an MIT graduate student, oversaw the project.
Synthetic Spinal Discs from a Penn Research Team Might Be the Solution to Chronic Back Pain
Spinal discs, the concentric circles of collagen fiber found between each vertebra of the spine, can be the source of immense back pain when ruptured. Especially for truck and bus drivers, veterans, and cigarette smokers, there is an increased risk in spinal disc rupture due to overuse or deterioration over time. But these patients aren’t alone. In fact, spinal discs erode over time for almost everyone, and are one of the sources of back pain in older patients, especially when the discs erode so much that they allow direct bone-to-bone contact between two or more vertebrae.
Robert Mauck, Ph.D., who is the director of the McKay Orthopaedic Research Laboratory here at Penn and a member of the Bioengineering Graduate Group Faculty, led a research team in creating artificial spinal discs, with an outer layer made from biodegradable polymer and an inner layer made with a sugar-like gel. Their findings appear in Science Translational Medicine. These synthetic discs are also seeded with stem cells that produce collagen over time, meant to replace the polymer as it degrades in vivo over time. Though Mauck and his time are still far from human clinical trials for the discs, they’ve shown some success in goat models so far. If successful, these biodegradable discs could lead to a solution for back pain that integrates itself into the human body over time, potentially eliminating the need of multiple invasive procedures that current solutions require. Mauck’s work was recently featured in Philly.com.
An Untethered, Light-Activated Electrode for Innovations in Neurostimulation
Neurostimulation, a process by which nervous system activity can be purposefully modulated, is a common treatment for patients with some form of paralysis or neurological disorders like Parkinson’s disease. This procedure is typically invasive, and because of the brain’s extreme sensitivity, even the slightest involuntary movement of the cables, electrodes, and other components involved can lead to further brain damage through inflammation and scarring. In an effort to solve this common problem, researchers from the B.I.O.N.I.C. Lab run by Takashi D.Y. Kozai, Ph. D., at the University of Pittsburgh replaced long cables with long wavelength light and a formerly tethered electrode with a smaller, untethered one.
The research team, which includes Pitt senior bioengineering and computer engineering student Kaylene Stocking, centered the device on the principle of the photoelectric effect – a concept first described in a publication by Einstein as the local change in electric potential for an object when hit with a photon. Their design, which includes a 7-8 micron diameter carbon fiber implant, is now patent pending, and Kozai hopes that it will lead to safer and more precise advancements in neurostimulation for patients in the future.
A New Microfluidic Chip Can Detect Cancer in a Drop of Blood
Many forms of cancer cannot be detected until the disease has progressed past the point of optimum treatment time, increasing the risk for patients who receive late diagnoses of these kinds of cancer. But what if the diagnostic process could be simplified and made more efficient so that even a single drop of blood could be enough input to detect the presence of cancer in a patient? Yong Zeng, Ph.D., and his team of researchers at the University of Kansas in Lawrence sought to answer that question.
They designed a self-assembled 3D-nanopatterned microfluidic chip to increase typical microfluidic chip sensitivity so that it can now detect lower levels of tumor-associated exosomes in patient blood plasma. This is in large part due to the nanopatterns in the structure of the chip, which promote mass transfer and increase surface area, which in turn promotes surface-particle interactions in the device. The team applied the device to their studies of ovarian cancer, one of the notoriously more difficult kinds of cancer to detect early on in patients.
A Wearable Respiration Monitor Made from Shrinky Dinks
Michelle Khine, Ph. D., a professor of biomedical engineering at the University of California, Irvine incorporates Shrinky Dinks into her research. After using them once before in a medical device involving microfluidics, her lab recently worked to incorporate them into a wearable respiration monitor – a device that would be useful for patients with asthma, cystic fibrosis, and other chronic pulmonary diseases. The device has the capability to track the rate and volume of its user’s respiration based on measurements of the strain at the locations where the device makes contact with the user’s abdomen.
Paired with Bluetooth technology, this sensor can feed live readings to a smartphone app, giving constant updates to users and doctors, as opposed to the typical pulmonary function test, which only provides information from the time at which the test takes a reading. Though Khine and her team have only tested the device on healthy patients so far, they look forward to testing with patients who have pulmonary disorders, in hopes that the device will provide more comprehensive and accessible data on their respiration.
People and Places
Ashley Kimbel, a high school senior from Grissom High School in Huntsville, Alabama, designed a lightweight prosthetic leg for local Marine, Kendall Bane, after an attack in Afghanistan led him to amputate one of his legs below the knee. Bane, who likes to keep as active as possible, said the new lighter design is more ideal for activities like hiking and mountain biking, especially as any added weight makes balance during these activities more difficult. Kimbel used a CAD-modeling software produced by Siemens called Solid Edge, which the company hopes to continue improving in accessibility so that more students can start projects like Kimbel’s.
We would also like to congratulate Eva Dyer, Ph.D., and Chethan Pandarinath, Ph.D., both of whom are faculty members at the Walter H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, on receiving research fellowships from the Alfred P. Sloan Foundation. Dr. Dyer, who formerly worked with Penn bioengineering faculty member Dr. Konrad Kording while he was at Northwestern University, leads research in the field of using data analysis methods to quantify neuroanatomy. Dr. Pandarinth leads the Emory and Georgia Tech Systems Neural Engineering Lab, where he works with a team of researchers to use properties of artificial intelligence and machine learning to better understand large neural networks in the brain.
The BE Seminar Series continues this week. We hope to see you there!

“Microfluidics and Immuno-Materials for Organs-on-a-Chip”
This presentation will describe microfluidic technologies to conveniently produce life-like pulsatile flows along with applications to study of lung injury, enhancement of in vitro fertilization, and analysis of frequency-dependent cellular responses. The microfluidic technologies range from adaptation of piezo-electric actuator arrays from Braille displays to design of microfluidic circuits that can be designed to switch fluid flow on and off periodically on their own. The presentation will also describe engineered materials to mimic an aspect of the innate immune system to combat bacterial infection. More specifically, reconstituted chromatin microwebs inspired by neutrophil extracellular traps. Using a defined composition reconstituted chromatin microweb, we reveal impact of microweb DNA-histone ratio on bacteria capture. Additionally, we found that E. coli, including clinical isolates and resistant strains, are killed more efficiently by the last-resort antibiotic, colistin, when bound to microwebs. Recent efforts towards incorporation of these materials into human cell systems will also be described. Time permitting, topics on organoids, fibrosis, liquid-liquid phase separation, and scaling may be incorporated.
The Department of Bioengineering at the University of Pennsylvania would like to congratulate LeAnn Dourte, Ph.D. on her recent promotion to Practice Associate Professor. Formerly a Senior Lecturer, this promotion reflects Dr. Dourte’s innovative approaches to pedagogy since arriving at Penn in 2011. The title of Practice Associate Professor reflects exceptional accomplishment in teaching, leadership, and educational programs. As an official member of the faculty, this formalizes Dourte’s role as a leader in pedagogy and educational scholarship, furthering empowering her to think creatively and progressively about higher education.
As a key member of the BE teaching faculty, Dourte has regularly taught core undergraduate subjects such as Intro to Biomechanics (BE 200) and Biomaterials (BE 220) as well as popular graduate electives Biomechanics and Biotransport (BE 510) and Biomechatronics (BE 570). In particular, she spearheaded the department’s initiative to improve classroom and learning experiences through experimentation with the Structured, Active, In-Class Learning (or SAIL) model of education which emphasizes teamwork and dynamic problem-solving. Dourte worked with the Center for Teaching and Learning to understand this model and assess how it would best be applicable for BE students, and then presented her findings at national conferences and to the BE faculty, helping to introduce them to these techniques and advise them on best practices. Other BE faculty such as Chris Fang-Yen, Ph.D., Jennifer Philips-Cremins, Ph.D., and Danielle Bassett, Ph.D., have experimented with and incorporated these ideas into their courses. Thanks to Dourte’s efforts, BE has been integral in demonstrating the success of SAIL classes to the School of Engineering and then spreading this philosophy to other schools at Penn. In addition to her pedagogical interests, Dourte is also highly involved in the Department’s student wellness initiative, serving on the Department’s Climate Committee and as the Wellness Ambassador.
Now that she has achieved this latest milestone, Dourte has set her sights on goals for the future. She intends to work with Associate Dean for Undergraduate Education Dr. Russ Composto to strengthen initiatives to assist SEAS’s First-Generation, Low-Income (FGLI) students. She will be working with Dr. Bassett, who specializes in network science, to learn more about how students learn, and what tools can be developed to assess students in addition to traditional exams and homework; to tell more easily when students are missing key concepts; and to intervene sooner in moments of crisis. And finally, Dourte will also be one of three representatives from Penn at an upcoming national education summit this May to discuss the future of Bioengineering curricula.
“Our best educators are teachers for the rest of the faculty, as well as the students,” says Department Chair Dr. David Meaney. “We are enormously proud of the prestige and expertise that LeAnn shares with all of us. I was fortunate to teach biomechanics with LeAnn for many years, and saw her outstanding ability as an educator in person.”
Once again, we would like to extend hearty congratulations to Dr. Dourte on this well-deserved recognition of her leadership and both in and out of the classroom.
Louisiana Tech Sends First All-Female Team to RockOn
A team of faculty and students from Louisiana Tech University will participate in RockOn, a NASA-sponsored workshop on rocketry and engineering. Mechanical Engineering Lecturer Krystal Corbett, Ph.D., and Assistant Professor of bioengineering Mary Caldorera-Moore, Ph.D., will work together to lead the university’s first team of three all-female students at the event. At the program, they will have the chance to work on projects involving components of spacecraft systems, increasing students’ experience in hands-on activities and real-world engineering.
Refining Autism Treatments Using Big Data
Though treatments like therapy and medication exist for patients with autism, one of the biggest challenges that those caring for these patients face is in measuring their effects over time. Many of the markers of progress are qualitative, and based on a given professional’s opinion on a case-by-case basis. But now, a team of researchers from Rensselaer Polytechnic Institute (RPI) hopes to change that with the use of big data.
Juergen Hahn, Ph. D., and his lab recently published a paper in Frontiers in Cellular Neuroscience discussing their findings in connecting metabolic changes with behavioral improvements in autistic patients. Their analysis looks for multiple chemical and medical markers simultaneously in data from three distinct clinical trials involving metabolic treatment for patients. Being able to quantitatively describe the effects of current autism treatments would revolutionize clinical trials in the field, and lead to overall better patient care.
Penn Engineers Can Detect Ultra Rare Proteins in Blood Using a Cellphone Camera
One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many conditions, such as the early detection of certain cancers or the diagnosis of traumatic brain injury, where the relevant biomarkers only appear in vanishingly small quantities. Commercial approaches to ultrasensitive protein detection are starting to become available, but they are based on expensive optics and fluid handlers, which make them relatively bulky and expensive and constrain their use to laboratory settings.
Knowing that having this sort of diagnostic system available as a point-of-care device would be critical for many conditions — especially traumatic brain injury — a team of engineers led by Assistant Professor in the Department of Bioengineering, David Issadore, Ph.D., at the University of Pennsylvania have developed a test that uses off-the-shelf components and can detect single proteins with results in a matter of minutes, compared to the traditional workflow, which can take days.
Treating Cerebral Palsy with Battery-Powered Exoskeletons
Cerebral palsy is one of the most common movement disorders in the United States. The disorder affects a patient’s control over even basic movements like walking, so treatments for cerebral palsy often involve the use of assistive devices in an effort to give patients better command over their muscles. Zach Lerner, Ph.D., is an Assistant Professor of Mechanical Engineering and faculty in Northern Arizona University’s Center for Bioengineering Innovation whose research looks to improve these kinds of assistive devices through the use of battery-powered exoskeletons.
Lerner and his lab recently received three grants, one each from the National Institute of Health (NIH), the National Science Foundation (NSF), and the Arabidopsis Biological Resource Center, to continue their research in developing these exoskeletons. Their goal is to create devices with powered assistance at joints like the ankle or knee to help improve patient gait patterns in rehabilitating the neuromuscular systems associated with walking. The team hopes that their work under these new grants will help further advance treatment for children with cerebral palsy, and improve overall patient care.
People & Places
David Aguilar, a 19-year-old bioengineering student at Universitat Internacional de Catalunya made headlines recently for a robotic prosthetic arm that he built for himself using Lego pieces. Due to a rare genetic condition, Aguilar was born without a right forearm, a disability that inspired him to play with the idea of creating his own prosthetic arm from age nine. His design includes a working elbow joint and grabber that functions like a hand. In the future, Aguilar hopes to continue improving his own prosthetic designs, and to help create similar versions of affordable devices for other patients who need them.
This week, we would like to congratulate two recipients of the National Science Foundation’s Career Awards, given to junior faculty that exemplify the role of teacher-scholars in their research. The first recipient we’d like to acknowledge is the University of Arkansas’ Kyle Quinn, Ph.D., who received the award for his work in developing new image analysis methods and models using the fluorescence of two metabolic cofactors. Dr. Quinn completed his Ph.D. here at Penn in Dr. Beth Winkelstein’s lab, and received the Solomon R. Pollack Award for Excellence in Graduate Bioengineering Dissertation Research for his work.
The second recipient of the award we wish to congratulate is Reuben Kraft, Ph.D., who is an Assistant Professor in Mechanical and Biomedical Engineering at Penn State. Dr. Kraft’s research centers around developing computational models of the brain through linking neuroimaging and biomechanical assessments. Dr. Kraft also collaborates with Kacy Cullen, Ph.D., who is a secondary faculty member in Penn’s bioengineering department and a member of the BE Graduate Group faculty.
Finally, we’d like to congratulate Dawn Elliott, Ph.D., on being awarded the Orthopaedic Research Society’s Adele L. Boskey, PhD Award, awarded annually to a member of the Society with a commitment to both mentorship and innovative research. Dr. Elliott’s spent 12 years here at Penn as a member of the orthopaedic surgery and bioengineering faculty before joining the University of Delaware in 2011 to become the founding director of the bioengineering department there. Her research focuses primarily on the biomechanics of fibrous tissue in tendons and the spine.
Dr. Shaffer’s research is is focused on understanding how differences present in single-cells can generate phenotypes such as drug resistance in cancer, oncogenesis, differentiation, and invasion. Our approach leverages cutting-edge technologies including high-throughput imaging, single-molecule RNA FISH, fluorescent protein tagging, CRISPR/Cas9 screening, and flow cytometry to investigate rare single-cell phenomena. Further information can be found at www.sydshafferlab.com.
In addition to her exciting research, Dr. Shaffer will be an enthusiastic new member of the Bioengineering Department community. In the short term, she will be taking over the popular class BE 400 (Preceptorships in Bioengineering) which gives undergraduates the rare chance to shadow renowned physicians over a period of ten weeks. She will also serve as a faculty advisor as well as a mentor to the lucky students in her classes and lab.
Dr. Shaffer says that, “With my research interests and training at the interface of engineering and medicine, I am thrilled to be part of the highly interdisciplinary community of Penn Bioengineering.”
“Sydney has a unique combination of creativity and impact in her work,” says Solomon R. Pollack Professor and Chair Dr. David Meaney. “Her work to untangle the secrets of how single cancer cells can develop resistance to a cancer drug — therefore leading to a return of the cancer — is nothing short of stunning. We are incredibly fortunate to have her on our faculty. ”
Detecting Infectious Diseases with Paper-Based Devices
Despite great advancements in diagnostics technology over the past few decades, patient accessibility to these technologies remains one of the biggest challenges of the field today. Particularly in low-resource areas, even simple processes can end up taking weeks or months to return results from tests that are normally completed in days. But what if these tests could be simplified to smaller, at-home tests based on properties of microfluidics – something like a pregnancy test but for infectious diseases like HIV?
Jacqueline Linnes, Ph.D., and her team of researchers at Purdue University are working towards finding a way to do just that by creating paper-based devices that use microfluidics to help carry out the necessary diagnostic tests. Specifically, her lab designed such a paper-based system that can detect HIV nucleic acids within 90 minutes of receiving a drop of patient blood. The success of this design shows promise for producing devices for diseases whose diagnostics process involve similar pathways of pathogen detection, opening the door to more applications of at-home tests based in the properties of paper microfluidics.
Here at Penn, undergraduate bioengineering students enrolled in the two-semester laboratory course Bioengineering Modeling, Analysis, and Design (BE 309 & BE 310) have the chance to create their own models of paper microfluidics delivery systems based on given time constraints in a multi-step process. Though the students’ challenge only involves water as a substrate, Linnes’ research demonstrates the later implications of studying fluid flow through a medium as cheap and accessible as paper.
Watch the video below demonstrating Dr. Linnes’ device:
Funding for Cancer Research in Tumor Mimicry and Imaging
Two of the deadliest forms of cancer today are breast cancer and pancreatic cancer, with the latter having a five-year survival rate of only about 8%. Because cancer treatments are often adjusted according to a unique patient-to-patient basis, learning how to improve predictions of tumor behavior could help determine proper therapies sooner.
Chien-Chi Lin, Ph.D., an associate professor of biomedical engineering at Indiana University – Purdue University Indianapolis, recently received a grant from the National Institute of Health to advance his research in pancreatic cancer treatment. His project under the grant involves the development of bio-inspired, responsive, and viscoelastic (BRAVE) cell-laden hydrogels to help understand cell interactions in pancreatic ductal adenocarcinoma, which is the most common form of malignancy in the pancreas. These hydrogels mimic tumor tissue, as well as model tumor development over time, helping to eventually find better ways of treating pancreatic cancer.
Penn’s Women in Computer Science (WiCS) Hosts FemmeHacks
Penn President Amy Gutmann and Penn Engineering Dean Vijay Kumar stopped by FemmeHacks at the Pennovation Center Feb. 9. The annual event is a beginner-friendly collegiate hackathon for women-identifying people with an interest in computer programming, and featured a day of all-levels workshops Feb. 8. The event is sponsored by Penn’s Women in Computer Science student organization.
Though the event is not specifically tailored towards applications in bioengineering, skills relating to coding and software development are increasingly important for those interested in pursuing a career in medical device design. In fact, in the evaluation of new medical devices, the FDA often focuses more on software over hardware, as the former is associated with more security liabilities, due to its relative novelty.
Case Western Reserve University and Cleveland Clinic announced the launch of an alliance last year with the goal of creating better synergy across the two renowned institutions, hoping to provide more opportunities for students with interest in medicine at all levels, from high school to postdoctoral education. Though researchers from both institutions frequently partner on projects, this new alliance will create a more structured platform for future collaborations.
We would like to commend Steven George, M.D./Ph.D., on his new position as the chair of the Department of Biomedical Engineering at the University of California at Davis. His research involves the development of “organ-on-a-chip” technologies using stem cells and microfluidics to mimic human organ functions of vascularized cardiac, tumor, and pancreatic tissues.
Finally, we want to congratulate Paul Yock, M.D., on his being chosen to receive the National Academy of Engineering’s 2019 Fritz J. and Dolores H. Russ Prize. The prize honors two of Dr. Yock’s inventions from his research in interventional cardiology, one of which is Rapid Exchange, which is a kind of stenting and balloon angioplasty system. Dr. Yock is the Martha Meier Weiland Professor in the School of Medicine and Professor of Bioengineering.
Heart disease is currently the leading cause of death in the United States, resulting in about 630,000 deaths every year according to the Center for Disease Control. One of the most common side effects of heart disease is damage to blood vessels and cardiac tissue, which can ultimately lead to conditions like high blood pressure, arrhythmia, and even cardiac arrest. In serious cases of irreversible heart damage, often the only option for patients is a full heart transplant, and efforts to engineer vascularized cardiac tissue grafts have proved challenging in research so far.
But researchers Ying Zheng, Ph.D., and Charles Murry, M.D., Ph.D., both of whom have joint appointments in Bioengineering at the University of Washington, have found success in using human microvascular grafts to create working blood vessels in vitro to treat infarcted rat hearts. The new heart muscle, developed from human embryonic stem cell-derived endothelial cells in petri dishes, was grown with a focus on not only being able to easily integrate it in vivo, but also in creating a patch of vasculature that closely mirrored that of the heart. In concentrating more on the mechanical aspects of the blood vessel network, Zheng and Murry were able to better restore normal blood flow to the damaged rat hearts after integration of the grafts. The study appears in a recent edition of Nature Communications.
Another team of bioengineers, led by Michael Sacks, Ph.D. at the University of Texas at Austin, recently invented a software-based method for repairing mitral valves in the heart. Their work, published in the International Journal for Numerical Methods in Biomedical Engineering, uses computational modeling techniques to create a noninvasive way of simulating repairs to the mitral valve, which will allow for a better prediction of surgical procedures and postoperative side effects on a more patient-specific basis. This ability to know which treatment plan may be best-suited for a given patient is important especially for valve repair, as heart valves are notoriously difficult to model or image due to the complexity of their functions. But through the use of advanced technology in 3D echocardiography, Sacks and his team say that their new model is accurate enough to rely on in clinical settings.
Virtual Reality Assists in the Evaluation of Surgery
Any form of surgery is always a high risk procedure, as it is subject to a wide variety of sources of human error and irregularity, even with the best surgeons. Certainly, there should be a system in place to not only continually assess the knowledge of surgeons throughout their careers, but also to evaluate their practices and techniques during operation. Such an evaluation, however, would put patients at risk during the assessment of the surgeon.
But now a team of researchers from Rensselaer Polytechnic Institute has developed a way of simulating colorectal surgical procedures using virtual reality technology. Suvranu De, Sc.D. — the J. Erik Jonsson ‘22 Distinguished Professor of Engineering and Head of the Department of Mechanical, Aerospace and Nuclear Engineering with joint appointments in Biomedical Engineering and Information Technology and Web Science —leads the project which incorporates both visual and tactile feedback for users to employ as a tool for both training and evaluating colorectal surgeons. While virtual reality simulators have been used for similar applications related to procedures like the colonoscopy, they have yet to be fully developed for open surgical procedures, because of the difficulties in creating a fully engaged and immersive environment. Nonetheless, De and his team hope that their work will lead to the creation of the first “Virtual Intelligent Preceptor,” which will allow for more advanced technological innovations in aspects of surgical education that have so far been difficult to standardize. Support for the project comes from the National Institute of Biomedical Imaging and Bioengineering (NBIB).
Penn BE’s Dr. Bassett on Understanding Knowledge Networks in the Brain
As a network neuroscientist, Danielle Bassett, Ph.D., Eduardo D. Glandt Faculty Fellow and Associate Professor in the Department Bioengineering, brings together insights from a variety of fields to understand how the brain’s connections form and change: mathematics, physics, electrical engineering and developmental biology, to name a few. Bassett’s recent work on the learning process also draws from linguistics, educational theory and other domains even further afield.
The intersection and interaction of knowledge from multiple sources doesn’t just describe Bassett’s methodology; it’s at the heart of her research itself. At the Society for Industrial and Applied Mathematics’ Annual Meeting last year, Bassett provided an address on how the structure of knowledge networks can influence what our brains can do when it comes to learning new things.
The field of bioengineering is constantly growing, and new programs are always in development. Boise State University has announced the launch of a new doctoral program in bioengineering that will begin in the fall of 2019. Developed through the collaboration of the university’s College of Health Sciences, College of Engineering, Graduate College, and College of Arts and Sciences, this new opportunity to do research in the field of bioengineering will have three study tracks available in biomechanics, mechanobiology, and human performance.
The new biomedical engineering department at the University of Massachusetts Amherst has announced the department’s first faculty appointments. The founding department head will be Professor Tammy L. Haut Donahue, Ph.D., whose research focus is on the biomechanics of the musculoskeletal system. Another professor joining the department’s new faculty is Seth W. Donahue, Ph.D., who has also done research in the field of biomechanics, and specifically how it pertains to tissue regeneration.
Since we last posted, there have also been several significant academic appointments in the field of Bioengineering. This week, we would like to congratulate Bruce Tromberg, Ph.D., on his appointment as the director of the National Institute of Biomedical Imaging and Bioengineering (NIBIB). Dr. Tromberg is currently a Professor with appointments in Biomedical Engineering and Surgery at the University of California at Irvine, where he leads research in bioimaging and biophotonics. He has also served on the External Advisory Board of NIH P41 Center for Magnetic Resonance and Optical Imaging here at Penn since 2009, and has also given several lectures here on his work in bioimaging.
Secondly, we congratulate the University of Toronto’s Professor Warren Chan, Ph.D., who was recently named as a Tier 1 Canada Research Chair in Nanobioengineering. Professor Chan, who is also the director of the Institute of Biomaterials and Biomedical Engineering at the University of Toronto, conducts research in the field of nanotechnology for applications in the treatment and diagnosis of cancer and viral diseases.
And finally, we also want to congratulate Frank Pintar, Ph.D., on his appointment as the Founding Chair of the Marquette University and Medical College of Wisconsin. Dr. Pintar’s research in bioengineering involves the study of the biomechanics involved with brain and spinal cord injury, with a focus on motor vehicle crash trauma.
In a paper recently published in Biochemistry, a group of University of Pennsylvania Bioengineering students describe the results of their work designing a new, open-source, low-cost microplate reader. Plate readers are instruments designed to measure light absorption and fluorescence emission from molecules useful for clinical biomarker analyses and assays in a diverse array of fields including synthetic biology, optogenetics, and photosensory biology. This new design costs less than $3500, a significantly lower price than other commercially available alternatives. As described in the paper’s abstract, this design is the latest in a growing trend of open-source hardware to enhance access to equipment for biology labs. The project originated as part of the annual International Genetically Engineering Machine Competition (iGEM), an annual worldwide competition focusing on “push[ing] the boundaries of synthetic biology by tackling everyday issues facing the world” (iGEM website).
The group consists of current junior Andrew Clark (BSE ’20) and recent graduates Karol Szymula (BSE ’18), who works in the lab of Dr. Danielle Bassett, and Michael Patterson (BSE ’18), a Master’s student in Bioengineering and Engineer of Instructional Laboratories. Assistant Professor of Bioengineering Dr. Brian Chow served as their faculty mentor alongside Director of Instructional Labs Sevile Mannickarottu and Michael Magaraci, a Ph.D. candidate in Bioengineering, all of whom serve as co-authors on the published article. The research and design of the project was conducted in the Stephenson Foundation Bioengineering Educational Laboratory here at the University of Pennsylvania’s Department of Bioengineering.
