Unlocking Nature’s Secrets: Sherry Gao Pushes the Boundaries of Genetic Engineering

by Ian Scheffler

Sherry (Xue) Gao, Presidental Penn Compact Associate Professor in Chemical and Biomolecular Engineering and in Bioengineering

Sherry (Xue) Gao, Presidential Penn Compact Associate Professor in Chemical and Biomolecular Engineering (CBE), always knew she had a future in the lab. “I grew up in China, and when I was little, maybe six or seven,” she recalls, “my teacher asked me, ‘What do you want to be when you grow up?’ I said, ‘I want to be a scientist!’”

Neither of her parents had studied beyond high school; when Gao finished her training as a chemical engineer, she became the first person in her family to graduate from college. “One of my greatest motivations is to help first-generation college students,” Gao says.

Now, as the newest faculty member in CBE, Gao is prepared to do just that: support the next generation of chemical engineers, while also conducting groundbreaking research in the development of small molecules to edit genes, pushing the boundaries of precision medicine.

The Presidential Penn Compact Professorships were created by former Penn President Amy Gutmann specifically to recruit and support faculty like Gao: transformative leaders working at the intersection of multiple fields with “a yen for collaboration,” as Gutmann told the Penn Gazette in 2021.

Gao joins Penn Engineering from Rice University, where she collected numerous accolades, including the 2024 BMES-CMBE Rising Star Award, a 2022 NSF CAREER Award, the 2022 Outstanding Young Faculty at Rice School of Engineering Award and the 2020 NIH MIRA R35 Award.

As a member of the Center for Precision Engineering for Health (CPE4H), Gao will partner with colleagues from across the School to develop technologies that bridge disciplines, all in the interest of advancing health care. “We are very excited to have Sherry as a new member of the Center,” says Daniel Hammer, Alfred G. and Meta A. Ennis Professor and inaugural Director of CPE4H. “Gene editing is an important new tool that can precisely alter cell behavior by deleting or redirecting cell pathways, as well as enhancing and suppressing gene expression. She will have significant interactions with other members of the Center, such as Mike Mitchell and myself, as well as the broader Penn community, especially with the CAR therapists.”

Daniel Hammer and Michael Mitchell both hold primary appointments in Bioengineering.

The Future of Medicine Rises in University City: University of Pennsylvania Opens New Multi-Disciplinary Research Labs in One uCity Square

by Holly Wojcik

One uCity Square

On September 14, Wexford Science & Technology, LLC and the University of Pennsylvania announced that the University has signed a lease for new laboratory space that will usher in a wave of novel vaccine, therapeutics, and engineered diagnostics research to West Philadelphia. Research teams from Penn are poised to move into 115,000 square feet of space at One uCity Square, the 13-story, 400,000 square foot purpose-built lab and office building within the vibrant uCity Square Knowledge Community being developed by Wexford. This is the largest lease in the building, encompassing four floors, and bringing the building to over 90% leased. The building currently includes industry tenants Century Therapeutics (NASDAQ: IPSC), Integral Molecular, Exponent (NASDAQ: EXPO), and Charles River Laboratories (NYSE: CRL).

The new University space will house Penn Medicine’s Institute for RNA Innovation and Penn Engineering’s Center for Precision Engineering for Health, underscoring the University’s commitment to a multi-disciplinary and collaborative approach to research that will attract and retain the best talent and engage partners from across the region. Penn’s decision to locate at One uCity Square reinforces uCity Square’s evolution as a central cluster of academic, clinical, commercial, entrepreneurial, and amenity spaces for the area’s innovation ecosystem, and further cements Philadelphia’s position as a top life sciences market.

Jonathan Epstein, MD, Executive Vice Dean and Chief Scientific Officer of Penn Medicine, shared his anticipation for the opportunities that lie ahead: “Penn Medicine is proud to build on its existing clinical presence in uCity Square and establish an innovative and collaborative research presence at the heart of uCity Square’s multidisciplinary innovation ecosystem. This strategic move underscores our commitment to accelerating advancements in biomedical research, industry collaboration, and equipping our talented teams with the resources they need to shape the future of healthcare.”

Locating the Penn Institute for RNA Innovation in the heart of the uCity Square community brings together researchers across disciplines who are already pursuing new vaccines and treatments, and better ways to deliver them. Their shared work will help to power the next phase of vaccine discovery and development.

Likewise, anchoring the work of Penn Engineering’s Center in the One uCity Square space will allow the School’s multi-disciplinary researchers and their collaborators to advance new clinical and diagnostic methods that will focus on intelligent therapeutics, genome design, diagnostics for discovery of human biology, and engineering the human immune shield.

“Penn Engineering has made a substantial commitment to precision engineering for health, an area that is not only important and relevant to engineering, but also critical to the future of humanity,” said Vijay Kumar, Nemirovsky Family Dean of Penn Engineering. “The space in One uCity Square will add another 30,000 square feet of space for our engineers to develop technologies that will fight future pandemics, cure incurable diseases, and extend healthy life spans around the world.”

Spearheading the Penn Institute for RNA Innovation will be Drew Weissman, MD, PhD, the Roberts Family Professor for Vaccine Research, who along with Katalin Karikó, PhD, adjunct professor of Neurosurgery, discovered foundational mRNA technology that enabled the creation of vital vaccine technology, including the FDA-approved mRNA-based COVID-19 vaccines developed by Pfizer-BioNTech and Moderna.

In this new space at One uCity Square, Weissman and his research team and collaborators will further pursue their groundbreaking research efforts with a goal to develop new therapeutics and vaccines and initiate clinical trials for other devastating diseases.

In addition, two established researchers will join the Institute at One uCity Square: Harvey Friedman, MD, a professor of Infectious Diseases, who leads a team researching various vaccines. He will be joined by Vladimir Muzykantov, MD, PhD, Founders Professor in Nanoparticle Research, who focuses on several projects related to targeting the delivery of drugs, including mRNA, to create more effective, targeted pathways to deliver drugs to the vascular system, treating a wide range of diseases that impact the brain, lung, heart, and blood.

Dan Hammer, Alfred G. and Meta A. Ennis Professor in the Departments of Bioengineering and Chemical and Biomolecular Engineering in Penn Engineering and Director of the Center for Precision Engineering for Health, will oversee the Center’s innovations in diagnostics and delivery, cellular and tissue engineering, and the development of new devices that integrate novel materials with human tissues. The Center will bring together scholars from all departments within Penn Engineering and will help to foster increased collaboration with campus colleagues at Penn’s Perelman School of Medicine and with industry partners.

Joining the Center researchers in One uCity Square are Noor Momin, Sherry Gao, and Michael Mitchell. Noor Momin, who will join Penn Engineering in early 2024 as an assistant professor in Bioengineering, will leverage her lab’s expertise in cardiovascular immunology, protein engineering and pharmacokinetic modeling to develop next-generation treatments and diagnostics for cardiovascular diseases.

Puneeth Guruprasad Wins 2023 Penn Prize for Excellence in Teaching by Graduate Students

Front, from left to right: Lucy Andersen, Vice Provost for Education Karen Detlefsen, Derek Yang, Ann Ho, and Arianna James. Back, from left to right: Ritesh Isuri, Adiwid (Boom) Devahastin Na Ayudhya, Oualid Merzouga, and Puneeth Guruprasad.

Ten winners of the 2023 Penn Prize for Excellence in Teaching by Graduate Students were announced at a ceremony held April 13 at the Graduate Student Center. The recipients, who represented five of Penn’s 12 schools, were recognized among a pool of 44 Ph.D. candidates and master’s students nominated primarily by undergraduates—a quality unique to and cherished about this Prize.

“It’s a particularly authentic expression of gratitude from undergraduates, and that’s really the pleasure [of presenting these awards],” says Vice Provost for Education Karen Detlefsen, who was present to announce the winners and award them with a certificate. (They also receive a monetary award.) “I’m so proud of our students: Our undergraduates, for taking the time to recognize what it is our graduate students contribute to the student body, and the graduate students who are contributing to the life of the University.

“Students are the lifeblood of the University and without them, we wouldn’t be here.”

The Prize began in the 1999-2000 academic year under former Penn President Judith Rodin. It was spearheaded by then-doctoral-candidate Eric Eisenstein and has been issued every year since. Nominations for the Prize often mention how graduate teaching assistants were able to take a complex subject and make it relatable or craft a course like philosophy or mathematics into an enjoyable—even highly anticipated—experience for students.

“Many nominations show how much students value a TA or a graduate instructor of record who shows that they care for their learning and for them as people, and who makes themself readily available to assist,” says Ian Petrie, director of graduate student programming for the Center for Teaching and Learning, who organizes the selection committee for the Prize. “Typically, however, committee members are also interested in seeing nominations that really point to how a graduate student instructor taught or gave feedback—not just how responsive they were to emails or how many office hours they had.”

He also emphasizes that many winners this year were not just teachers, but mentors—often helping undergraduates or new graduate students navigate not only the course but also Penn as an institution.

Puneeth Guruprasad

One of the winners, Puneeth Guruprasad, hails from Penn Bioengineering. Guruprasad is a fourth-year Ph.D. student in Bioengineering who conducts research in the lab of Marco Ruella, Assistant Professor of Medicine in the Division of Hematology/Oncology in the Perelman School of Medicine. Ruella is also a member of the Center for Cellular Immunotherapies (CCI) and the Penn Bioengineering Graduate Group.

Guruprasad studies mechanisms of resistance to chimeric antigen receptor (CAR) T cell therapy for cancer. He has served as a teaching assistant for five semesters: three for Intro to Biotransport Processes (BE 3500) taught by Alex Hughes, Assistant Professor in Bioengineering, and two for Cellular Engineering (BE 3060), taught by Daniel Hammer, Alfred G. and Meta A. Ennis Professor in Bioengineering and in Chemical and Biomolecular Engineering. Both courses are a part of the core curriculum for undergraduate bioengineering students. His doctoral thesis focuses on how a specific interaction between CAR T cells and tumor cells limits their function across a range of cancers.

“I make myself approachable outside the classroom, and I think that’s one aspect of being a TA: having responsibilities that extend beyond the classroom,” says Guruprasad. “Dozens of times, I’ve spoken to students over coffee, or over some lunch, about what direction they want to take in their life, what they want to do outside of the course, and give them my two cents of advice. I try to individualize.”

The Penn Center for Precision Engineering for Health Announces First Round of Seed Funding

by Melissa Pappas

CPE4H is one of the focal points of Penn Engineering signature initiative on Engineering Health.

The Penn Center for Precision Engineering for Health (CPE4H) was established late last year to accelerate engineering solutions to significant problems in healthcare. The center is one of the signature initiatives for Penn’s School of Engineering and Applied Science and is supported by a $100 million commitment to hire faculty and support new research on innovative approaches to those problems.

Acting on that commitment, CPE4H solicited proposals during the spring of 2022 for seed grants of $80K per year for two years for research projects that address healthcare challenges in several key areas of strategic importance to Penn: synthetic biology and tissue engineering, diagnosis and drug delivery, and the development of innovative devices. While the primary investigators (PIs) for the proposed projects were required to have a primary faculty appointment within Penn Engineering, teams involving co-PIs and collaborators from other schools were eligible for support. The seed program is expected to continue for the next four years.

“It was a delight to read so many novel and creative proposals,” says Daniel A. Hammer, Alfred G. and Meta A. Ennis Professor in Bioengineering and the Inaugural Director of CPE4H. “It was very hard to make the final selection from a pool of such promising projects.”

Judged on technical innovation, potential to attract future resources, and ability to address a significant medical problem, the following research projects were selected to receive funding.

Evolving and Engineering Thermal Control of Mammalian Cells

Led by Lukasz Bugaj, Assistant Professor in Bioengineering, this project will engineer molecular switches that can be toggled on and off inside mammalian cells at near-physiological temperatures. Successful development of these switches will provide new ways to communicate with cells, an advance that could be used to make safer and more effective cellular therapies.  The project will use directed evolution to generate and find candidate molecular tools with the desired properties. Separately, the research will also develop new technology for manipulating cellular temperature in a rapid and programmable way. Such devices will enhance the speed and sophistication of studies of biological temperature regulation.

A Quantum Sensing Platform for Rapid and Accurate Point-of-Care Detection of Respiratory Viral Infections

Combining microfluidics and quantum photonics, PI Liang Feng, Professor in Materials Science and Engineering and Electrical and Systems Engineering, Ritesh Agarwal, Professor in Materials Science Engineering, and Shu Yang, Joseph Bordogna Professor in Materials Science and Engineering and Chemical and Biomolecular Engineering, are teaming up with Ping Wang, Professor of Pathology and Laboratory Medicine in Penn’s Perelman School of Medicine, to design, build and test an ultrasensitive point-of-care detector for respiratory pathogens. In light of the COVID-19 pandemic, a generalizable platform for rapid and accurate detection of viral pathogenesis would be extremely important and timely.

Versatile Coacervating Peptides as Carriers and Synthetic Organelles for Cell Engineering

PI Amish Patel, Associate Professor in Chemical and Biomolecular Engineering, and Matthew C. Good, Associate Professor of Cell and Developmental Biology in the Perelman School of Medicine and in Bioengineering, will design and create small proteins that self-assemble into droplet-like structures known as coacervates, which can then pass through the membranes of biological cells. Upon cellular entry, these protein coacervates can disassemble to deliver cargo that modulates cell behavior or be maintained as synthetic membraneless organelles. The team will design new chemistries that will facilitate passage across cell membranes, and molecular switches to sequester and release protein therapeutics. If successful, this approach could be used to deliver a wide range of macromolecule drugs to cells.

Towards an Artificial Muscle Replacement for Facial Reanimation

Cynthia Sung, Gabel Family Term Assistant Professor in Mechanical Engineering and Applied Mechanics and Computer Information Science, will lead a research team including Flavia Vitale, Assistant Professor of Neurology and Bioengineering, and Niv Milbar, Assistant Instructor in Surgery in the Perelman School of Medicine. The team will develop and validate an electrically driven actuator to restore basic muscle responses in patients with partial facial paralysis, which can occur after a stroke or injury. The research will combine elements of robotics and biology, and aims to produce a device that can be clinically tested.

“These novel ideas are a great way to kick off the activities of the center,” says Hammer. “We look forward to soliciting other exciting seed proposals over the next several years.”

Alexander Buffone Appointed Assistant Professor at New Jersey Institute of Technology

Alexander Buffone, Ph.D.

Penn Bioengineering is proud to congratulate Alexander Buffone, Ph.D. on his appointment as Assistant Professor in the Department of Biomedical Engineering at New Jersey Institute of Technology. His appointment began in the Spring of 2022.

Buffone got his Ph.D. in Chemical Engineering from SUNY Buffalo in Buffalo, NY in 2012, working with advisor Sriram Neelamegham, Professor of Chemical and Biological Engineering. Buffone completed previous postdoctoral studies at Roswell Park Comprehensive Cancer Center with Joseph T.Y. Lau, Distinguished Professor of Oncology in the department of Cellular and Molecular Biology. Upon coming to Penn in 2015, Buffone has worked in the Hammer Lab under advisor Daniel A. Hammer, Alfred G. and Meta A. Ennis Professor in Bioengineering and in Chemical and Biomolecular Engineering, first as a postdoc and later a research associate. Buffone also spent a year as a Visiting Scholar in the Center for Bioengineering and Tissue Regeneration, directed by Valerie M. Weaver, Professor at the University of California, San Francisco in 2019.

While at Penn, Buffone was a co-investigator on an R21 grant through the National Institutes of Health (NIH) which supported his time as a research associate. Buffone is excited to start his own laboratory where he plans to train a diverse set of trainees.

Buffone’s research area lies at the intersection of genetic engineering, immunology, and glycobiology and addresses how to specifically tailor the trafficking and response of immune cells to inflammation and various diseases. The work seeks to identify and subsequently modify critical cell surface and intracellular signaling molecules governing the recruitment of various blood cell types to distal sites. The ultimate goal of his research is to tailor and personalize the innate and adaptive immune response to specific diseases on demand.

“None of this would have been possible without the unwavering support of all of my mentors, past and present, and most especially Dan Hammer,” Buffone says. “His support in helping me transition into an independent scientist and his understanding of my outside responsibilities as a dad with two young children is truly the reason why I am standing here today. It’s a testament to Dan as both a person and a mentor.”

Daniel A. Hammer and Miriam Wattenbarger to Offer Summer Course on COVID-19

Daniel A. Hammer and Miriam Wattenbarger

As researchers hunt for a solution to the coronavirus outbreak, Daniel A. Hammer, Alfred G. and Meta A. Ennis Professor in Bioengineering and in Chemical and Biomolecular Engineering (CBE), is bringing lessons from the fight for a vaccine to the classroom.

Hammer will offer a course on COVID-19 and the coronavirus pandemic during Penn’s Summer II session, which will be held online this year. The course will be co-taught with Miriam Wattenbarger, senior lecturer in CBE.

The course, “Biotechnology, Immunology, and COVID-19,” will culminate with a case study of the coronavirus pandemic including the types of drugs proposed and their mechanism of action, as well as the process of vaccine development.

“Obviously, the pandemic has been a life-altering event, causing an immense dislocation for everyone in our community, especially the students. Between me and Miriam, who has been trumpeting the importance of vaccines for some time in her graduate-level CBE courses, we have the expertise to inform students about this disease and how we might combat it,” says Hammer.

For more than ten years, Wattenbarger has run courses and labs focused on drug delivery and biotechnology, key elements of the vaccine development process.

“I invite both researchers and industry speakers to meet with my students,” Wattenbarger says, “so that they learn the crucial role engineers play in both vaccine development and manufacturing.”

Beyond studying the interactions between the immune system and viruses — including HIV, influenza, adenovirus and coronavirus — students will cover a variety of biotechnological techniques relevant to tracking and defending against them, including recombinant DNA technology, polymerase chain reaction, DNA sequencing, gene therapy, CRISPR-Cas9 editing, drug discovery, small molecule inhibitors, vaccines and the clinical trial process.

Students will also learn the mathematical principles used to quantify biomolecular interactions, as well as those found behind simple epidemiological models and methods for making and purifying drugs and vaccines.

“We all have to contribute in the ways that we can. Having taught biotechnology to freshmen for the past decade, this is something that I can do that can both inform and build community,” says Hammer. “Never has it been more important to have an informed and scientifically literate community that can fight this or any future pandemic.”

Though these projects are all works in progress, I think it is vitally important to keep those in our broader communities informed of the critical contributions our people are making. Whether adapting current research to focus on COVID-19, investing time, technology, and equipment to help health care infrastructure, or creating new outreach and educational programs for students, I am incredibly proud of the way Penn Bioengineering is making a difference. I invite you to read more about our ongoing projects below.

RESEARCH

Novel Chest X-Ray Contrast

David Cormode, Associate Professor of Radiology and Bioengineering

Nanomedicine and Molecular Imaging Lab

Peter Noel, Assistant Professor of Radiology and BE Graduate Group Member

Laboratory for Advanced Computed Tomography Imaging

The Cormode and Noel labs are working to develop dark-field X-ray imaging, which may prove very helpful for COVID patients. It involves fabricating diffusers that incorporate gold nanoparticles to modify the X-ray beam. This method gives excellent images of lung structure. Chest X-ray is being used on the front lines for COVID patients, and this could potentially be an easy to implement modification of existing X-ray systems. The additional data give insight into the health state of the microstructures (alveoli) in the lung. This new contrast mechanics could be an early insight into the disease status of COVID-19 patients. For more on this research, see Cormode and Noel’s chapter in the forthcoming volume Spectral, Photon Counting Computed Tomography: Technology and Applications, edited by Katsuyuki Taguchi, Ira Blevis, and Krzysztof Iniewski (Routledge 2020).

Immunotherapy

Michael J. Mitchell, Skirkanich Assistant Professor of Innovation in Bioengineering

Mitchell Lab

Mike Mitchell is working with Saar Gill (Penn Medicine) on engineering drug delivery technologies for COVID-19 mRNA vaccination. He is also developing inhalable drug delivery technologies to block COVID-19 internalization into the lungs. These new technologies are adaptations of prior research published Volume 20 of Nano Letters (“Ionizable Lipid Nanoparticle-Mediated mRNA Delivery for Human CAR T Cell Engineering” January 2020) and discussed in Volume 18 of Nature Reviews Drug Discovery (“Delivery Technologies for Cancer Immunotherapy” January 2019).

Respiratory Distress Therapy Modeling

Ravi Radhakrishnan, Professor, and Chair of Bioengineering and Professor of Chemical and Biomolecular Engineering

Radhakrishnan Lab

Computational Models for Targeting Acute Respiratory Distress Syndrome (ARDS). The severe forms of COVID-19 infections resulting in death proceeds by the propagation of the acute respiratory distress syndrome or ARDS. In ARDS, the lungs fill up with fluid preventing oxygenation and effective delivery of therapeutics through the inhalation route. To overcome this major limitation, delivery of antiinflammatory drugs through the vasculature (IV injection) is a better approach; however, the high injected dose required can lead to toxicity. A group of undergraduate and postdoctoral researchers in the Radhakrishnan Lab (Emma Glass, Christina Eng, Samaneh Farokhirad, and Sreeja Kandy) are developing a computational model that can design drug-filled nanoparticles and target them to the inflamed lung regions. The model combines different length-scales, (namely, pharmacodynamic factors at the organ scale, hydrodynamic and transport factors in the tissue scale, and nanoparticle-cell interaction at the subcellular scale), into one integrated framework. This targeted approach can significantly decrease the required dose for combating ARDS. This project is done in collaboration with Clinical Scientist Dr. Jacob Brenner, who is an attending ER Physician in Penn Medicine. This research is adapted from prior findings published in Volume 13, Issue 4 of Nanomedicine: Nanotechnology, Biology and Medicine: “Mechanisms that determine nanocarrier targeting to healthy versus inflamed lung regions” (May 2017).

Diagnostics

Sydney Shaffer, Assistant Professor of Bioengineering and Pathology and Laboratory Medicine

Syd Shaffer Lab

Arjun Raj, Professor of Bioengineering

Raj Lab for Systems Biology

David Issadore, Associate Professor of Bioengineering and Electrical and Systems Engineering

Issadore Lab

Arjun Raj, David Issadore, and Sydney Shaffer are working on developing an integrated, rapid point-of-care diagnostic for SARS-CoV-2 using single molecule RNA FISH. The platform currently in development uses sequence specific fluorescent probes that bind to the viral RNA when it is present. The fluorescent probes are detected using a iPhone compatible point-of-care reader device that determines whether the specimen is infected or uninfected. As the entire assay takes less than 10 minutes and can be performed with minimal equipment, we envision that this platform could ultimately be used for screening for active COVID19 at doctors’ offices and testing sites. Support for this project will come from a recently-announced IRM Collaborative Research Grant from the Institute of Regenerative Medicine with matching funding provided by the Departments of Bioengineering and Pathology and Laboratory Medicine in the Perelman School of Medicine (PSOM) (PI’s: Sydney Shaffer, Sara Cherry, Ophir Shalem, Arjun Raj). This research is adapted from findings published in the journal Lab on a Chip: “Multiplexed detection of viral infections using rapid in situ RNA analysis on a chip” (Issue 15, 2015). See also United States Provisional Patent Application Serial No. 14/900,494 (2014): “Methods for rapid ribonucleic acid fluorescence in situ hybridization” (Inventors: Raj A., Shaffer S.M., Issadore D.).

Penn Engineers Coax White Blood Cells to Crawl Upstream, Enabling Faster Route to Infections

When the immune system detects a foreign pathogen, a cascade of chemical signals call white blood cells to the scene. Neutrophils are the most common and abundant type of these cells and while they start accumulating at the site of an infection within minutes, they are essentially at the mercy of the circulatory system’s one-way flow of traffic to get them where they need to go.

Now, research from the University of Pennsylvania’s School of Engineering and Applied Science shows how these cells can be coaxed to fight the direction of blood flow, crawling upstream along the walls of veins and arteries.

The in vitro study suggested that this technique could get neutrophils to the sites of infections faster when they are restricted to the direction of blood flow.

Alexander Buffone and Daniel Hammer

Daniel A. Hammer, Alfred G. and Meta A. Ennis Professor in the Department of Bioengineering, and Alexander Buffone, Jr., a research associate in his lab, led the research. Nicholas R. Anderson, a graduate student in the Hammer lab, also contributed to the study.

Provost’s Award Given to Hammer for PhD Mentoring

Provost's Award
Daniel Hammer, PhD

Last night, Daniel A. Hammer, PhD, Alfred G. and Meta A. Ennis Professor of Bioengineering and Professor of Chemical & Biomolecular Engineering at the University of Pennsylvania, was recognized with the 2018 Provost’s Award For Distinguished PhD Teaching and Mentoring. This University-wide honor has been awarded annually to two Penn faculty members for the last 15 years.

With an undergraduate degree in Chemical Engineering from Princeton and a PhD from Penn, Dr. Hammer joined the faculty at Cornell in Chemical Engineering after a short postdoctoral appointment in 1988. He was awarded tenure there and came to Penn in 1996. He holds a joint appointment in Bioengineering and Chemical Engineering, and he spent almost seven years as department chair, including serving as Principal Investigator of Penn’s Whitaker Foundation Leadership-Development Award, which led to the hiring of 8 faculty members in Bioengineering and provided seed money for the construction of Skirkanich Hall.

Among Dr. Hammer’s previous honors are an NSF Presidential Young Investigator Award in 1982, election as a Fellow of the AIMBE in 1997, and the Penn SEAS Heilmeier Faculty Award for Excellence in Research in 2004. Dr. Hammer has mentored a total of 51 PhD students, many of who have become faculty members themselves, including three recipients of NSF Career Awards.

“I am deeply honored to win the PhD mentoring award, which is a testament to the quality, inventiveness, and drive of my doctoral students. I have very much enjoyed training these young people in Penn’s fertile scientific environment, and it’s been a singular joy to see their careers flourish.”
