The Office of the Provost awards the Penn Prize for Excellence in Teaching by Graduate Students in recognition of their profound impact on education across the University. Nominations come directly from undergraduate and graduate students in their courses and are narrowed down to ten awardees each year.
Muir has served as a teaching assistant for coursework in Biomaterials with Skirkanich Assistant Professor of Innovation Michael Mitchell and Tissue Engineering with Robert D. Bent Professor Jason Burdick. She is conducting her thesis on granular hydrogels for musculoskeletal tissue repair under Burdick’s advisement. Muir has also received both NSF and Tau Beta Pi Fellowships for her graduate studies.
Election to the AIMBE College of Fellows is among the highest professional distinctions accorded to a medical and biological engineer. College membership honors those who have made outstanding contributions to “engineering and medicine research, practice, or education” and to “the pioneering of new and developing fields of technology, making major advancements in traditional fields of medical and biological engineering, or developing/implementing innovative approaches to bioengineering education.”
Bassett was nominated, reviewed, and elected by peers and members of the College of Fellows for “significant contributions to the application of neural network theory for understanding both physio and patho-physiological brain function.”
As a result of health concerns, AIMBE’s annual meeting and induction ceremony scheduled for March 29–30, 2020, was cancelled. Under special procedures, Bassett was remotely inducted along with 156 colleagues who make up the AIMBE College of Fellows Class of 2020.
“The Born Award recognizes Nader Engheta’s exceptional contributions to the fields of metamaterials, transformation optics and nanophotonics,” said 2020 OSA President Stephen D. Fantone, founder and president of Optikos Corporation. “This honor is emblematic of the pioneering work he has done in near-zero index metamaterials.”
We would like to congratulate Assistant Professor in Bioengineering Alex Hughes, Ph.D., on receiving the Maximizing Investigators’ Research Award (MIRA) from the National Institutes of Health (NIH), which funds investigators to create flexible and forward-thinking research programs. Hughes is the first recipient of this award in Penn’s School of Engineering and Applied Science, marking a major accomplishment for him and his lab.
The award recognizes Hughes’ efforts to create new tools used for tissue engineering, in particular by fusing concepts from developmental biology into tissue construction efforts. Hughes believes this approach will have impacts on fundamental understanding human disease, leading to new strategies to combat them. Hughes and his lab specifically focus on kidney disease. As Hughes says, “defects in the kidney and urinary tract account for up to a third of all birth defects.” Furthermore, because kidney development involves many different kinds of cell interactions, there’s a gap in understanding exactly how these defects occur.
Unlike other grants that focus on funding projects, the MIRA prioritizes the people behind the research, giving them funding as a sign of faith in the future work they’ll choose to do. “The MIRA has allowed us significant leeway to integrate several complementary approaches here,” Hughes says. Because of this flexibility, Hughes and his lab thinks it will allow them to reach for more innovative and risky approaches in their research, in the hopes that this will lead to a better understanding of kidney defects and modes of treatment for them.
As he processed down Locust Walk the day of Commencement, Michael Wong didn’t miss a beat. He took in with pride all his interactions with friends, every cheer from the crowd, and each step on his final day as an undergraduate at Penn.
The first in his family to go to college, Wong would not only graduate that day with a degree from the Wharton School. Thanks to a President’s Innovation Prize (PIP), he’d also graduate with a full-fledged startup and significant funding in hand, ready and willing to take on his next chapter.
“The whole day of graduation I was like ‘Wow, this is amazing,’” recalls Wong. “It’s one of my favorite moments.”
Wong, from Oakland, California, founded InstaHub in 2016. Working with Dayo Adewole, a doctoral candidate in the School of Engineering and Applied Science, the pair designed a snap-on motion sensor device that attaches onto existing light switches. It is battery powered, with occupancy sensing capabilities, and is easy to install. With PIP, which awarded Wong $100,000 (plus $50,000 for living expenses), he says he’s been able to do rapid prototyping to move InstaHub forward.
Jason Burdick, Robert D. Bent Professor in the Department of Bioengineering, has been named a Fellow of the National Academy of Inventors (NAI), an award of high professional distinction accorded to academic inventors. Elected Fellows have demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development and the welfare of society.
Burdick’s research interests include developing degradable polymeric biomaterials that can be used for tissue engineering, drug delivery, and fundamental polymer studies. His lab focuses on developing polymeric materials for biomedical applications with specific emphasis on tissue regeneration and drug delivery. Burdick believes that advances in synthetic chemistry and materials processing could be the answer to organ and tissue shortages in medicine. The specific targets of his research include: scaffolding for cartilage regeneration, controlling stem cell differentiation through material signals, electrospinning and 3D printing for scaffold fabrication, and injectable hydrogels for therapies after a heart attack.
On the second floor of the Pennovation Center, Strella Biotechnology is hard at work turning their student-led startup into a full-fledged company that’s ready to make a major impact in the agricultural sector.
May graduates Katherine Sizov and Malika Shukurova, respectively the CEO and head of R&D at Strella, share a 2019 President’s Innovation Prize, which includes $100,000 of financial support, a $50,000 living stipend for both awardees, and a year of dedicated co-working and lab space at the Pennovation Center. The alumnae and their company are now poised to take on the challenge of $1 trillion worth of food waste.
Strella’s biosensors are designed to give packers real-time data on how ripe their fruits are while being stored between harvesting and selling. Using bio-inspired sensors that measure the ethylene gas produced by fruits as they ripen, Strella successfully “hacked the fruit” to create their patent-pending biosensors. Now, only six months after graduation, Strella has six paying customers and is aiming for $100,000 in sales by the end of the season.
Beyond the work needed to deploy their first paid product, Strella also has a clear view of what needs to be done for future progress of the company. This means running experiments in the lab to refine their current sensors while conducting other experiments that will help the company be able to monitor other types of fresh foods. It’s a job that Shukurova says involves a lot of multitasking and requires an “all-hands” approach to problem solving.
“We set up experiments that run for several days, and during that period we work on different tasks. I prepare for the next set of experiments, Jacob [Jordan] and Katherine travel to our customers to deploy sensors, and Zuyang [Liu]]works on IoT [Internet of Things]. At the end of the day we all come together to discuss results and future plans,” says Shukurova about their company’s work flow.
Last spring, we congratulated Penn Bioengineering graduating senior Oladunni Alomaja (BSE ’19) and her partners at Rebound Liberia on their President’s Engagement Prize. Check out the article and video below on their exciting project.

Fueled by the encouragement and support they received this spring and summer, the three Penn alumni behind Rebound Liberia are now laser-focused on carrying their mission of promoting education and empowerment straight to the basket.
The Rebound Liberia team is led by Princess Aghayere, Oladunni Alomaja, and Summer Kollie, all May Penn graduates who received the President’s Engagement Prize — a $100,000 project prize and $50,000 living stipend per team member, awarded for post-graduation projects that make a positive, lasting difference in the world. The trio, each of whom has connections to West Africa and strives to give back, proposed an NGO that would bridge the literacy gap in post-conflict Liberia between male and female youth through workshops and a basketball program for women.
On Sept. 4, after months of preparation, the team relocated to Monrovia, Liberia, and is settling in.
“I think there’s some cultural shock,” says Aghayere, musing about the adjustment. “But Penn is a great place to travel and a lot of us took advantage of opportunities to travel. I’m not surprised, because this is not my first time on the continent, but there are things unique about Liberia. Getting used to the accents, the weather, the currency — but it’s fun.”
Aghayere and Alomaja were born in Nigeria, while Kollie is from Liberia.
Their days so far, they explain, have been consistently jam-packed with meetings. At present, they’re planning an inter-school basketball tournament to introduce their program to Liberia; in recent weeks, they’ve made connections with school administrators, found their footing in the community, and worked through the logistics of organizing a tournament — which, they note, they had some practice with in 2018, creating a summer basketball clinic in Monrovia, Liberia, for girls that was hosted twice a week.
The upcoming tournament, which will include 120 female players on Nov. 22–24, represents a first step toward their larger intention to build a basketball court and program, and marry that with literacy resources. They aim to serve approximately 60 girls in their program.
“We didn’t think it would be wise to move in September and not have an event until the next June or so, so we thought [of] the tournament,” says Aghayere, explaining the origins of the tournament. “At first, we were thinking we’d have a team and foster the game amongst girls here in Monrovia, and we wanted to include a lot more girls and create this sort of league of our own while introducing ourselves as this new social enterprise in Liberia. We thought a tournament would be a launch of Rebound Liberia and introduce us to the community here.”
Positive results in first-in-U.S. trial of CRISPR-edited immune cells
Genetically editing a cancer patient’s immune cells using CRISPR/Cas9 technology, then infusing those cells back into the patient appears safe and feasible based on early data from the first-ever clinical trial to test the approach in humans in the United States. Researchers from the Abramson Cancer Center have infused three participants in the trial thus far—two with multiple myeloma and one with sarcoma—and have observed the edited T cells expand and bind to their tumor target with no serious side effects related to the investigational approach. Penn is conducting the ongoing study in cooperation with the Parker Institute for Cancer Immunotherapy and Tmunity Therapeutics.
“This trial is primarily concerned with three questions: Can we edit T cells in this specific way? Are the resulting T cells functional? And are these cells safe to infuse into a patient? This early data suggests that the answer to all three questions may be yes,” says the study’s principal investigator Edward A. Stadtmauer, section chief of Hematologic Malignancies at Penn. Stadtmauer will present the findings next month at the 61st American Society of Hematology Annual Meeting and Exposition.
Because of the opioid epidemic sweeping the nation, Moore notes that there’s a rapid search going on to develop non-addictive painkiller options. However, he also sees a gap in adequate models to test those new drugs before human clinical trials are allowed to take place. Here is where he hopes to step in and bring some innovation to the field, by integrating living human cells into a computer chip for modeling pain mechanisms. Through his research, Moore wants to better understand not only how some drugs can induce pain, but also how patients can grow tolerant to some drugs over time. If successful, Moore’s work will lead to a more rapid and less expensive screening option for experimental drug advancements.
New machine learning-assisted microscope yields improved diagnostics
Researchers at Duke University recently developed a microscope that uses machine learning to adapt its lighting angles, colors, and patterns for diagnostic tests as needed. Most microscopes have lighting tailored to human vision, with an equal distribution of light that’s optimized for human eyes. But by prioritizing the computer’s vision in this new microscope, researchers enable it to see aspects of samples that humans simply can’t, allowing for a more accurate and efficient diagnostic approach.
Led by Roarke W. Horstmeyer, Ph.D., the computer-assisted microscope will diffuse light through a bowl-shaped source, allowing for a much wider range of illumination angles than traditional microscopes. With the help of convolutional neural networks — a special kind of machine learning algorithm — Horstmeyer and his team were able to tailor the microscope to accurately diagnose malaria in red blood cell samples. Where human physicians typically perform similar diagnostics with a rate of 75 percent accuracy, this new microscope can do the same work with 90 percent accuracy, making the diagnostic process for many diseases much more efficient.
Case Western Reserve University researchers create first-ever holographic map of brain
A Case Western Reserve University team of researchers recently spearheaded a project in creating an interactive holographic mapping system of the human brain. The design, which is believed to be the first of its kind, involves the use of the Microsoft HoloLens mixed reality platform. Lead researcher Cameron McIntyre, Ph.D., sees this mapping system as a better way of creating holographic navigational routes for deep brain stimulation. Recent beta tests with the map by clinicians give McIntyre hope that the holographic representation will help them better understand some of the uncertainties behind targeted brain surgeries.
More than merely providing a useful tool, McIntyre’s project also brings together decades’ worth of neurological data that has not yet been seriously studied together in one system. The three-dimensional atlas, called “HoloDBS” by his lab, provides a way of finally seeing the way all of existing neuro-anatomical data relates to each other, allowing clinicians who use the tool to better understand the brain on both an analytical and visual basis.
Implantable cancer traps reduce biopsy incidence and improve diagnostic
Biopsies are one of the most common procedures used for cancer diagnostics, involving a painful and invasive surgery. Researchers at the University of Michigan are trying to change that. Lonnie Shea, Ph.D., a professor of biomedical engineering at the university, worked with his lab to develop implants with the ability to attract any cancer cells within the body. The implant can be inserted through a scaffold placed under the patient’s skin, making it a more ideal option than biopsy for inaccessible organs like lungs.
The lab’s latest work on the project, published in Cancer Research, details its ability to capture metastatic breast cancer cells in vivo. Instead of needing to take biopsies from areas deeper within the body, the implant allows for a much simpler surgical procedure, as biopsies can be taken from the implant itself. Beyond its initial diagnostic advantages, the implant also has the ability to attract immune cells with tumor cells. By studying both types of cells, the implant can give information about the current state of cancer in a patient’s body and about how it might progress. Finally, by attracting tumor and immune cells, the implant has the ability to draw them away from the area of concern, acting in some ways as a treatment for cancer itself.
People and Places
The Philadelphia Inquirer recently published an article detailing the research of Penn’s Presidential Assistant Professor in Psychiatry, Microbiology, and Bioengineering, Cesar de la Fuente, Ph.D. In response to a growing level of worldwide deaths due to antibiotic-resistant bacteria, de la Fuente and his lab use synthetic biology, computation, and artificial intelligence to test hundreds of millions of variations in bacteria-killing proteins in the same experiment. Through his research, de la Fuente opens the door to new ways of finding and testing future antibiotics that might be the only viable options in a world with an increasing level of drug-resistant bacteria
Emily Eastburn, a Ph.D. candidate in Bioengineering at Penn and a member of the Boerckel lab of the McKay Orthopaedic Research Laboratory, recently won the Ashton fellowship. The Ashton fellowship is an award for postdoctoral students in any field of engineering that are under the age of 25, third-generation American citizens, and residents of either Pennsylvania or New Jersey. A new member of the Boerckel lab, having joined earlier this fall, Eastburn will have the opportunity to conduct research throughout her Ph.D. program in the developmental mechanobiology and regeneration that the Boerckel lab focuses on.
