The Hughes Lab in Penn Bioengineering works to “bring developmental processes that operate in vertebrate embryos and regenerating organs under an engineering control framework” in order to “build better tissues.” Hughes’s research interest is in harnessing the developmental principles of organs, allowing him to design medically relevant scaffolds and machines. In 2020 he became the first Penn Engineering faculty member to receive the Maximizing Investigators’ Research Award (MIRA) from the National Institutes of Health (NIH), and he was awarded a prestigious CAREER Award from the National Science Foundation (NSF) in 2021. Most recently, Hughes’s work has focused on understanding the development of cells and tissues in the human kidney via the creation of “organoids”: miniscule organ models that can mimic the biochemical and mechanical properties of the developing kidney. Understanding and engineering how the kidney functions could open doors to more successful regenerative medicine strategies to address highly prevalent congenital and adult diseases.
Hughes and his fellow award recipients were recognized at the annual BMES CBME conference in Indian Wells, CA in January 2023.
Penn Bioengineering alumna Cynthia Reinhart-King, Cornelius Vanderbilt Professor of Engineering and Professor of Biomedical Engineering at Vanderbilt University, was elected the next President of the Biomedical Engineering Society (BMES), the largest professional society for biomedical engineers. Her term as president-elect started at the annual BMES meeting in October 2021.
Reinhart-King graduated with her Ph.D. from Penn Bioengineering in 2006. She studied in the lab of Daniel Hammer, Alfred G. and Meta A. Ennis Professor in Bioengineering and Chemical and Biomolecular Engineering as a Whitaker Fellow and went on to complete postdoctoral training as an Individual NIH NRSA postdoctoral fellow at the University of Rochester. Prior to joining Vanderbilt, she was on the faculty of Cornell University and received tenure in the Department of Biomedical Engineering. The Reinhart-King lab at Vanderbilt “uses tissue engineering, microfabrication, novel biomaterials, model organisms, and tools from cell and molecular biology to study the effects of mechanical and chemical changes in tissues during disease progression.”
Reinhart-King gave the 2019 Grace Hopper Distinguished Lecture, sponsored by the Department of Bioengineering. This lecture series recognizes successful women in engineering and seeks to inspire students to achieve at the highest level. She is a recipient of numerous prestigious awards, including the Rita Schaffer Young Investigator Award in 2010, an NSF CAREER Award, and the Mid-Career Award in 2018 from BMES.
“BMES is facing many challenges, like many societies, as we deal with the hurdles associated with COVID-19 and inequities across society. We must continue to address those challenges. However, we are also in a terrific window of having robust membership, many members who are eager to get involved with the society’s activities, and a national lens on science and scientists. One of my goals will be to identify and create opportunities for our members to help build the reach of the society and its member.”

Sofia Gonzalez, who graduated with both bachelor’s and master’s degrees in Bioengineering this spring, was one of a select number of Penn students to receive 2021 Student Leadership Awards. Gonzalez was awarded a Penn Alumni Student Award of Merit as well as the William A. Levi Kite & Key Society Award for Service and Scholarship. Awardees were celebrated during the university’s annual Ivy Day, “a tradition recognizing students’ leadership, service, and scholarship for nearly 150 years.”
“Sofia reflected that on countless college tours, she noticed a striking pattern: only one of the ambassadors she encountered was a female engineer, and none of them were Latinx. While the nation was reckoning with racism, Sofia was leading critical discussions about how Kite & Key could improve in areas of diversity, equity, and inclusion to mirror the Penn student body. Sofia is now graduating, confident that she took measurable strides toward breaking the cycle of underrepresentation at America’s first University. Sofia’s work leaves a lasting legacy at Penn and beyond.”
Gonzalez also served as a Senior Advisor to the Biomedical Engineering Society (BMES) and as President of the Kite and Key Society, a society which welcomes all visitors to campus, acquaints prospective students and families with the undergraduate experience, and fosters a community of students dedicated to serving the University of Pennsylvania. Having completed her degrees, Gonzalez is headed for the first year of a rotational program as a member of the Merck Manufacturing Leadership Development Program in Durham, NC.
Following her time at Merck, Gonzalez will continue her education at the MIT Sloan School of Management. Gaining admission to the M.B.A. program via the Early Admission offering, she will matriculate within the following five years.
Diabetes is one of the more common diseases among Americans today, with the American Diabetes Association estimating that approximately 9.5 percent of the population battles the condition today. Though symptoms and causes may vary across types and patients, diabetes generally results from the body’s inability to produce enough insulin to keep blood sugar levels in check. A new experimental treatment from the lab of Sha Jin, Ph.D., a biomedical engineering professor at Binghamton University, aims to use about $1.2 million in recent federal grants to develop a method for pancreatic islet cell transplantation, as those are the cells responsible for producing insulin.
But the catch to this new approach is that relying on healthy donors of these islet cells won’t easily meet the vast need for them in diabetic patients. Sha Jin wants to use her grants to consider the molecular mechanisms that can lead pluripotent stem cells to become islet-like organoids. Because pluripotent stem cells have the capability to evolve into nearly any kind of cell in the human body, the key to Jin’s research is learning how to control their mechanisms and signaling pathways so that they only become islet cells. Jin also wants to improve the eventual culture of these islet cells into three-dimensional scaffolds by finding ways of circulating appropriate levels of oxygen to all parts of the scaffold, particularly those at the center, which are notoriously difficult to accommodate. If successful in her tissue engineering efforts, Jin will not only be able to help diabetic patients, but also open the door to new methods of evolving pluripotent stem cells into mini-organ models for clinical testing of other diseases as well.
A Treatment to Help Others See Better
Permanently crossed eyes, a medical condition called strabismus, affects almost 18 million people in the United States, and is particularly common among children. For a person with strabismus, the eyes don’t line up to look at the same place at the same time, which can cause blurriness, double vision, and eye strain, among other symptoms. Associate professor of bioengineering at George Mason University, Qi Wei, Ph.D., hopes to use almost $2 million in recent funding from the National Institute of Health to treat and diagnose strabismus with a data-driven computer model of the condition. Currently, the most common method of treating strabismus is through surgery on one of the extraocular muscles that contribute to it, but Wei wants her model to eventually offer a noninvasive approach. Using data from patient MRIs, current surgical procedures, and the outcomes of those procedures, Wei hopes to advance and innovate knowledge on treating strabismus.
A Newly Analyzed Brain Mechanism Could be the Key to Stopping Seizures
Among neurological disorders, epilepsy is one of the most common. An umbrella term for a lot of different seizure-inducing conditions, many versions of epilepsy can be treated pharmaceutically. Some, however, are resistant to the drugs used for treatment, and require surgical intervention. Bin He, Ph. D., the Head of the Department of Biomedical Engineering at Carnegie Mellon University, recently published a paper in collaboration with researchers at Mayo Clinic that describes the way that seizures originating at a single point in the brain can be regulated by what he calls “push-pull” dynamics within the brain. This means that the propagation of a seizure through the brain relies on the impact of surrounding tissue. The “pull” he refers to is of the surrounding tissue towards the seizure onset zone, while the “push” is what propagates from the seizure onset zone. Thus, the strength of the “pull” largely dictates whether or not a seizure will spread. He and his lab looked at different speeds of brain rhythms to perform analysis of functional networks for each rhythm band. They found that this “push-pull” mechanism dictated the propagation of seizures in the brain, and suggest future pathways of treatment options for epilepsy focused on this mechanism.
Hyperspectral Imaging Might Provide New Ways of Finding Cancer
A new method of imaging called hyperspectral imaging could help improve the prediction of cancerous cells in tissue specimens. A recent study from a University of Texas Dallas team of researchers led by professor of bioengineering Baowei Fei, Ph.D., found that a combination of hyperspectral imaging and artificial intelligence led to an 80% to 90% level of accuracy in identifying the presence of cancer cells in a sample of 293 tissue specimens from 102 patients. With a $1.6 million grant from the Cancer Prevention and Research Institute of Texas, Fei wants to develop a smart surgical microscope that will help surgeons better detect cancer during surgery.
Fei’s use of hyperspectral imaging allows him to see the unique cellular reflections and absorptions of light across the electromagnetic spectrum, giving each cell its own specific marker and mode of identification. When paired with artificial intelligence algorithms, the microscope Fei has in mind can be trained to specifically recognize cancerous cells based on their hyperspectral imaging patterns. If successful, Fei’s innovations will speed the process of diagnosis, and potentially improve cancer treatments.

Michael Mitchell, PhD, Skirkanich Assistant Professor of Innovation in the Department of Bioengineering at Penn, has been honored with a Rising Star Award in Cellular and Molecular Bioengineering from the Biomedical Engineering Society (BMES). According to the BMES website, “The BMES Cellular and Molecular Bioengineering Special Interest Group brings together researchers with diverse scientific and clinical interests with a common goal of understanding and engineering molecules, cells, their interactions and microenvironments in the pursuit of controlling biological processes and improving the practice of medicine.” Dr. Mitchell received the award and delivered a lecture at the 2019 Cellular and Molecular Bioengineering Conference in San Diego, California in January, 2019.
One of six early-stage investigators from across the nation to receive the honor, Dr. Mitchell was recognized for his work on engineering delivery technologies for cancer gene therapy and immunotherapy, which is helping to lay the foundation for a new class of therapeutic strategies against hematologic cancers such as multiple myeloma and leukemia. In 2018, Dr. Mitchell was awarded the NIH Director’s New Innovator Award for this research, and received the Burroughs Wellcome Fund Career Award at the Scientific Interface) in 2016. He joined the Penn faculty in January 2018 after completing an NIH NCI postdoctoral fellowship with Dr. Robert Langer at the Koch Institute for Integrative Cancer Research at MIT.
Jason Burdick, Ph.D., who is a professor in the University of Pennsylvania’s Department of Bioengineering, has been named one of the three chairs of the 2019 annual meeting of the Biomedical Engineering Society (BMES), which be held here in Philadelphia on October 16-19. Dr. Burdick will share this position with two other Philadelphians: Alisa Morss Clyne, Ph.D., an associate professor of mechanical engineering and mechanics at Drexel University; and Ruth Ochia, Ph.D., an associate professor of instruction in bioengineering at Temple University. Drs. Burdick, Clyne, and Ochia will share the responsibility for planning the meeting and chairing it once it is in session.
“I am very happy to be appointed as a program chair for the 2019 BMES meeting in Philadelphia, along with Alisa Morss Clyne of Drexel University and Ruth Ochia of Temple University,” Dr. Burdick said when asked about the honor. “The three of us felt that it was important to represent the various biomedical engineering research and education programs within the city of Philadelphia, since the meeting will be held here. There is such a wealth of biomedical engineering efforts in Philly that provides great opportunities to engage in outreach and interaction with both the community and local industry during the meeting.”
Megan Sperry, a Ph.D. student in the Department of Bioengineering, is a recipient of a Student Design and Research Award from the Biomedical Engineering Society (BMES). Megan works in the Spine Pain Research Lab of Beth Winkelstein, Ph.D., professor of Bioengineering and Vice Provost for Education at Penn’s School of Engineering and Applied Science, as well as with Eric Granquist, DMD, MD, an oral and maxillofacial surgeon at Penn Dental Medicine.
With Drs. Winkelstein and Granquist, Megan studies temporomandibular joint (TMJ) pain and osteoarthritis, the latter of which can develop as a long-term consequence of untreated TMJ dysfunction. There’s currently no way to determine which patients will progress to TMJ osteoarthritis, so Megan’s extended abstract, which was submitted to the BMES competition, detailed a study using 18F-EF5 PET, an imaging modality used mainly in oncology. Hypothesizing that hypoxia, or low oxygen, was a key factor in the development of TMJ osteoarthritis, Megan studied the relationship between hypoxia and persistent TMJ pain and found that hypoxia preceded reorganization of the cartilage of the TMJ, part of the process culminating in TMJ osteoarthritis (see image below).
“This project has been both fun and challenging because it brings together concepts and techniques from multiple fields, including orthopedics, neuroscience, and, with the use of 18F-EF5, radiation oncology,” Megan said. “I’m excited to have the opportunity to share my work at the BMES Annual Meeting and receive feedback as we continue to move the project forward.”
Each year, BMES awards up to five graduate students the Student Design and Research Award from dozens of submissions. Congratulations to Megan for this elite recognition of her research!
The chapter of the Biomedical Engineering Society (BMES) at the University of Pennsylvania has won the Student Outreach Achievement Award from the society. This is the second time in three years that BMES at Penn has won the award, for which more than 60 other chapters compete.
The award acknowledges the efforts of Penn BMES to establish relationships with the surrounding community. For instance, Junior Beta Day, held in the spring semester, saw Penn BE students hosting approximately 60 local middle school students for a day on campus, during which they interacted with members of the faculty and engaged in activities centered on bioengineering. In addition, the Penn BMES chapter has participated in local neighborhood revitalization initiatives and acted as mentors.
“I’m very proud of our group’s outreach initiatives within the both the greater Philadelphia and campus communities,” said Sonia Bansal, who is one of the outreach chairs for the chapter. “Our partnerships with iPraxis and SPARK help us break down bioengineering concepts into approachable activities for middle school students. We hope that our programming shows students that they too can go on to be engineers and scientists, and its an incredibly rewarding experience to see students get excited about STEM.”
Founded in 1968, BMES is a 501(c)(3) nonprofit professional association acting as a lead society for 7,000 members and 115 student chapters.
