We would like to congratulate Dr. Yale Cohen, Ph.D., on his recent appointment as the new Graduate Group Chair for Penn’s Department of Bioengineering. The Graduate Group is a group of faculty that graduate students in bioengineering can choose from to collaborate with on lab research. The Group includes members from nearly all of Penn’s schools, including Penn Engineering, Penn Dental, Penn Medicine, Penn Vet, and the School of Arts and Sciences.
Dr. Cohen specializes in otorhinolaryngology as his primary department, with research areas in computational and experimental neuroengineering. He will take over the role of Graduate Group Chair from Dr. Ravi Radhakrishnan, Ph.D, professor of bioengineering and chemical and biomolecular engineering, whose research specializes in cellular, molecular, and theoretical and computational bioengineering. During his tenure as Graduate Group Chair, Dr. Radhakrishnan says that “the most enjoyable part was the student talks during bioengineering seminars, and the talks at the bioengineering graduate student research symposium,” noting the way they made him realize the “depth and breadth of our graduate group, and how accomplished our students are.”
Also during his time as chair, Dr. Radhakrishnan says he was proud to expand the course BE 699 — the Bioengineering Department’s required seminar for all Ph.D. candidates — to include discussions of leadership and soft-skills, as well as instituting individualized development plans to help students track their work. In looking forward to Dr. Cohen’s appointment to the role, Dr. Radhakrishnan says that he is “a natural and accomplished scientist, educator, and amazing leader who connects so readily and well with our students and faculty.”
Dr. Cohen, looking forward to taking on his new role, says that he hopes to improve programs like the Graduate Association of Bioengineers (GABE) and the mentoring of graduate students so that they can access the wide range of wisdom that comprises the faculty, students, staff, and alumni associated with the Graduate Group. “I am thrilled to be the new chair of the BE Graduate Group and welcome your input and comments on how to improve an already outstanding program,” says Dr. Cohen.
Each week, the National Science Foundation highlights “4 Awesome Discoveries You Probably Didn’t Hear About” — a kid-friendly YouTube series that highlights particularly eye-popping NSF-supported research.
This week, one of those stories was literally about an eye, or rather, a synthetic model of one.
Dan Huh, associate professor in the Department of Bioengineering, and graduate student Jeongyun Seo, recently published a paper that outlined their new blinking eye-on-a-chip. Containing human cells and mechanical parts designed to mimic natural biological functions, including a motorized eyelid, the device was developed as platform for modeling dry eye disease and testing drugs to treat it.

Brain stimulation, where targeted electrical impulses are directly applied to a patient’s brain, is already an effective therapy for depression, epilepsy, Parkinson’s and other neurological disorders, but many more applications are on the horizon. Clinicians and researchers believe the technique could be used to restore or improve memory and motor function after an injury, for example, but progress is hampered by how difficult it is to predict how the entire brain will respond to stimulation at a given region.
In an effort to better personalize and optimize this type of therapy, researchers from the University of Pennsylvania’s School of Engineering and Applied Science and Perelman School of Medicine, as well as Thomas Jefferson University Hospital and the University of California, Riverside, have developed a way to model how a given patient’s brain activity will change in response to targeted stimulation.
To test the accuracy of their model, they recruited a group of study participants who were undergoing an unrelated treatment for severe epilepsy, and thus had a series of electrodes already implanted in their brains. Using each individual’s brain activity data as inputs for their model, the researchers made predictions about how to best stimulate that participant’s brain to improve their performance on a basic memory test.
The participants’ brain activity before and after stimulation suggest the researchers’ models have meaningful predictive power and offer a first step towards a more generalizable approach to specific stimulation therapies.
The study, published in the journal Cell Reports, was led by Danielle Bassett, J. Peter Skirkanich Professor in Penn Engineering’s Department of Bioengineering, and Jennifer Stiso, a neuroscience graduate student in Penn Medicine and a member of Bassett’s Complex Systems Lab.
A New Sprayable Gel Can Help Prevent Surgical Adhesions
Adhesions are a common kind of scar tissue that can occur after surgery, and though usually not painful, they have the potential to result in complications like chronic pain or decreased heart efficiency, depending on where the scar tissue forms. Now, a sprayable gel developed by researchers at Stanford University will help to prevent adhesions from forming during surgical procedures. The gel, called PNP 1:10 in reference to its polymer-nanoparticle structure, has a similar stiffness to mayonnaise and achieves an ideal balance of slipperiness and stickiness that allows it to adhere easily to tissue of irregular shapes and surfaces. The flexible gel will actually dissolve in the body after two weeks, which is about how long most adhesions take to heal. Though lead author Lyndsay Stapleton, M.S., and senior authors Joseph Woo, M.D., and Eric Appel, Ph.D., have only tested the gel in rats and sheep so far, they hope that human applications are not too far in the future.
Learning to Understand Blood Clots in a New Model
Blood clots are the source of some of the deadliest human conditions and diseases. When a clot forms, blood flow can be interrupted, cutting off supply to the brain, heart, or other vital organs, resulting in potentially serious damage to the mind and body. For patients with certain bleeding disorders, clotting or the lack thereof can hold tremendous importance in surgery, and affect some of the typical procedures of a given operation. To help plan for such situations, researchers at the University of Buffalo created an in vitro model to help better illustrate the complex fluid mechanics of blood flow and clotting. Most importantly, this new model better demonstrates the role of shear stress in blood flow, and the way that it can affect the formation or destruction of blood clots – an aspect that current clinical devices often overlook. Led by Ruogang Zhao, Ph.D., the model can allow surgeons and hematologists to consider the way that certain chemical or physical treatments can affect clot formation on a patient-to-patient basis. The two key factors of the model are its incorporation of blood flow, and its relationship to shear stress, with clot stiffness through microfabrication technology using micropillars as force sensors for the stiffness. Going forward, Zhao and his research team hope to test the model on more patients, to help diversify the different bleeding disorders it can exhibit.
Training the Next Generation of Researchers
Rebecca Zappala, a junior from Miami, Florida who is majoring in bioengineering, worked in Grenoble this summer on new ways to harvest water from fog. She describes her research project as a “futuristic” way to collect water and says that she’s thankful for the opportunity to work on her first independent research project through the Research and Education in Active Coatings Technology (REACT) program.
After learning the technical skills she needed for her project, Zappala spent her summer independently working on new ways to modify her material’s properties while working closely with her French PI and a post-doc in the lab. She was surprised to see how diverse the lab was, with researchers working on everything from biomolecular research to energy in the same space.
“I learned a lot,” she says about being in such an interdisciplinary setting. “I hadn’t been part of a research team before, and I got a lot of exposure to things that I wouldn’t have been exposed to otherwise.”
Virginia Tech Course Addresses the Needs of Wounded Veterans
A new course at Virginia Tech encourages students to apply engineering skills to real-life problems in the biomedical world by designing medical devices or other applications to assist veterans suffering from serious injuries or illnesses. Funded by the National Institute of Health, faculty from the Department of Biomedical Engineering and Mechanics hope that the course will allow students to see how theoretical knowledge from the classroom actually works in a clinical setting, and to understand how different stakeholder interests factor into designing a real device. What makes this new class unique from other traditional design-focused courses at other universities is its level of patient interaction. Students at Virginia Tech who choose to take this class will have the chance to gain input from field professionals like clinicians and engineers from the Salem Veterans Affairs Medical Center, while also being able to get direct feedback from the patients that the devices will actually help. Beginning in the spring of 2020, students can take the new course, and volunteer in the veterans clinics to gain even more experience with patients.

Title: “Developing Neuroengineering Solutions of Biomedical Relevance Using Crayfish as a Model System”
In my talk, I will first describe one of the main projects in my lab that investigates the underlying cellular-molecular mechanisms for changes in alcohol sensitivity of crayfish with different prior social experiences. In this context, I will explain why “simple” invertebrates may provide unique advantages for studying complex phenomena such as socially-dependent drug effects. Crayfish are inexpensive and easily maintained in the laboratory, and they have an accessible nervous system with large, identified neurons that link directly to behavior and can sustain many hours of experimental study. This allows for high precision and reproducibility and makes crayfish a suitable model not just for investigating neurobehavioral questions, but for developing and improving biomedical devices and tools. In the second part of my talk, I will illustrate two projects that are currently ongoing in collaboration with engineering colleagues at UMD. The first one aims to develop nanoparticles that wirelessly activate and record neural activity patterns using microwave signals. Preliminary data using individual neurons of the ex vivo crayfish nerve cord revealed that single action potentials can be robustly recorded by activating microwave signals in a nanoscale magnetic tunnel junction. The future goal of this project is to develop this technique for non-invasive monitoring and modulating of activity in brains of higher complexity. The second project interfaces the crayfish ex vivo ventral nerve cord and innervated hindgut with a multi-sensor 3D printed platform that contains cultured human gut cells and interchangeable colonies of microbiota. The physiological responses to serotonin release from cell cultures will be measured and quantified in crayfish neurons of the central and enteric nervous system and on corresponding hindgut motility with intracellular electrophysiology and motion tracking. The long-term goal is to develop a real-time, high-throughput discovery platform that allows detailed investigation of the cellular processes underlying the gut-brain axis.
Dr. Jens Herberholz is an Associate Professor in the Psychology Department and the Director of the Neuroscience and Cognitive Science Program, an interdisciplinary, multi-departmental research and graduate training program at the University of Maryland, College Park. Dr. Herberholz received his PhD from the Technical University in Munich, Germany. His PhD work investigated the importance of mechanosensory signals during aggressive interactions in snapping shrimp. Following his PhD. he was a Postdoctoral Associate and Research Scientist at Georgia State University where he combined single-cell electrophysiology with behavioral analysis to study the neurobehavioral underpinnings of escape in crayfish. In his own laboratory, he continues to use crayfish as a primary animal model for research. Crayfish make complex behavioral decisions, and they feature an accessible nervous system with large, identifiable neurons, which allows for cellular and circuit-level analysis using neurophysiological, neuroanatomical, neurochemical, and neuroimaging techniques. His current research program focuses on identifying the structure and function of decision-making neural circuitry and understanding the interconnections between neural activity patterns and motor action in the context of aggression and predator avoidance. His most recent work addresses fundamental questions regarding the role of neurochemical inhibition, including the interplay between the neurocellular effects of alcohol and behavioral disinhibition, with the long-term goal of identifying how nervous system function is linked to adaptive and maladaptive behavioral output. Dr. Herberholz has published many peer-reviewed articles and conference abstracts as well as several book chapters on these topics; his research has been supported by the National Science Foundation (NSF), and featured by various media outlets. He is an Associate Editor for the journal “Behaviour”.

Electrode Arrays and Star Wars Help to Inspire a New Prosthetic Arm
After nearly fifteen years of work, a new high-tech prosthetic arm from researchers at the University of Utah allows hand amputees to pluck grapes, pick up eggs without breaking them, and even put on their wedding rings. Named after Luke Skywalker’s robotic hand in the Star Wars saga, the LUKE Arm includes sensors that better mimic the way the human body sends information to the brain, allowing users to distinguish between soft and hard surfaces and to perform more complicated tasks. The arm relies heavily on an electrode array invented by University of Utah biomedical engineering professor Richard A. Normann, Ph.D., which is a bundle of microelectrodes that enable a computer to read signals from connected nerves in the user’s forearm.
But the biggest innovation in the use of these electrode arrays for the LUKE Arm is in the way they allow the prosthetic to mimic the sense of feeling on the surface of an object that indicates how much pressure should be applied when handling it. Gregory Clark, Ph.D., an associate professor of biomedical engineering at the University of Utah and the leader of the LUKE Arm project, says the key to improving these functions in the prosthetic was by more closely mimicking the path that this information takes to the brain, as opposed to merely what comprises that sensory information. In the future, Clark hopes to improve upon the LUKE Arm by including more inputs, like one for temperature data, and on making them more portable by eliminating the device’s need for computer connection.
Philly Voice Recognizes the Cremins Lab’s Innovations in Light-Activated Gene-Folding
While technological advancements over the past few decades have opened doors to understanding the topological structures of DNA, we still have far more to learn about how these structures impact and contribute to genome function. But here at Penn, the Cremins Laboratory in 3D Epigenomes and Systems Neurobiology hopes to fix that. Led by Jennifer E. Phillips-Cremins, Ph.D., members of the lab use light-activated dynamic looping (LADL) to better understand the way that genome topological properties and folding can affect protein translation. Cremins and her lab use this technique to force specific genome folds to interact with each other, and create temporary DNA loops that can then be bound together in the presence of blue light for certain proteins in the Arabidopsis plant. Using the data from these tests, researchers can better understand the genome structure-function relationships, and hopefully open the door to new treatments for diseases in which expression or mis-expression of certain genes is the cause.
Artificial Cells Can Deliver Molecules Better than the Real Thing
From pills to vaccines, ways to deliver drugs into the body have been constantly evolving since the early days of medicine.
Now, a new study from an interdisciplinary team led by researchers at the University of Pennsylvania provides a new platform for how drugs could be delivered to their targets in the future. Their work was published in the Proceedings of the National Academy of Sciences.
The research focuses on a dendrimersome, a compartment with a lamellar structure and size that mimic a living cell. It can be thought of as the shipping box of the cellular world that carries an assortment of molecules as cargo.
The scientists found that these dendrimersomes, which have a multilayered, onion-like structure, were able to “carry” high concentrations of molecules that don’t like water, which is common in pharmaceutical drugs. They were also able to carry these molecules more efficiently than other commercially available vessels. Additionally, the building block of the cell-like compartment, a janus dendrimer, is classified as an amphiphile, meaning it contains molecules that don’t like water and also molecules that are soluble in water, like lipids, that make up natural membranes.
“This is a different amphiphile that makes really cool self-assembled onions into which we were able to load a bunch of molecular cargos,” says co-author Matthew Good.
In a recent review of over 5,000 sleep studies, biomedical engineering researchers at the University of Texas at Austin found a connection between water-based passive body heating and sleep onset latency, efficiency, and quality. Using meta-analytical tools to compare all of the studies and patient data, lead author and Ph.D. candidate Shahab Haghayegh and his team found that a warm bath in the temperature range of 104-109 degrees Fahrenheit taken 1-2 hours before bed has the ability to improve all three considered sleep categories. This makes sense considering that our body’s Circadian rhythms govern both our sleep cycles and temperature, bringing us to a higher temperature during the day and a lower one at night during sleep. In fact, this lowering of body temperature before sleep is what helps to trigger the onset of sleep, so taking a warm bath and allowing your body to cool down from it before going to sleep enhances the body’s own efforts of naturally cooling down before we go to bed. With this new and comprehensive review, those who suffer from poor sleep quality may soon find solace in temperature regulation therapy systems.

With the recent 50th anniversary of the first moon landing by Americans Neil Armstrong, Buzz Aldrin, and Michael Collins in 1969, ABC News looked back at one of the women involved in the project. Judy Sullivan was a biomedical engineer at the time of the project, and served as the lead engineer of the biomedical system for Apollo 11. In this role, she led studies on the astronauts’ breathing rates and sensor capabilities for the devices being sent into space to help the astronauts monitor their health. For the Apollo 11 mission and a lot of Sullivan’s early work at NASA, she worked on teams of all men, as women were often encouraged to become teachers, secretaries, or homemakers over other professions. Today, Sullivan says she’s thrilled that women have more career options to choose from, and wants to continue seeing more women getting involved in math and science.
We would like to congratulate Sanjay Kumar, M.D., Ph.D., on his appointment as the new Department Chair of Bioengineering at the University of California, Berkeley. Since joining the faculty in 2005, Kumar has received several prestigious awards including the NSF Career Award, the NIH Director’s New Innovator Award, the Presidential Early Career Award for Scientists and Engineers, and the Berkeley student-voted Outstanding Teacher Award.
We would like to congratulate Paul Ducheyne, Ph.D., a Professor in the Bioengineering Department and a Professor of Orthopaedic Surgery Research at Penn, on being selected for the International Award by the European Society for Biomaterials (ESB). The International Award is one of the ESB’s highest honors, recognizing scientists who have spent the majority of their careers outside of Europe. They are internationally recognized, have a high scientific profile, and have made major contributions to the field of biomaterials. Those nominated for the award typically also have had strong collaborations with the scientific community in Europe throughout their careers.
Beyond being a professor at Penn, Ducheyne is also the founder of XeroThera, a spin-out from Penn that develops novel concepts for tissue engineering and drug delivery based on his group’s twenty years of fundamental studies of sol gel-processed, nanoporous, oxide-based materials. XeroThera’s first product formulations focus on prophylaxis and treatment of surgical infections. A pipeline is being developed building from his group’s breakthrough data that demonstrate the utility of sol-gel synthesized silica-based nanoporous materials for therapeutic use. These materials may well represent a next generation of agents for delivery of drugs, including antibiotics, analgesics, and osteogenic and anti-inflammatory molecules.
In being selected for the International Award, Ducheyne joins only five previous recipients of it so far, a group of scientists that represents those at the top of the field in biomaterials worldwide. Ducheyne will give a presentation and award lecture for the ESB at its next annual meeting this September in Dresden, Germany. Read more about the ESB’s awards here and see the full list of 2019 awardees here.
