Innovation in Action: Penn Engineering’s 2024 Senior Design Project Competition

by Ian Scheffler

BE’s award-winning team, Epilog, at the 2024 Senior Design Awards.

How do you make robotics kits affordable for children in low-income countries? Speed up the manufacturing of organs-on-a-chip? Lower the environmental impact of condiments in restaurants?

If you’re a senior at Penn Engineering, the answer is to team up with your peers in the Senior Design Project Competition, which every year draws interdisciplinary groups from across the School’s six majors to solve real-world problems. Championed by the late Walter Korn (EE’57, GEE’68), a past president of the Engineering Alumni Society (EAS), Senior Design also invites alumni back to campus to evaluate the seniors’ year-long capstone projects.

Since the program started nearly two decades ago, hundreds of alumni have shared centuries’ worth of their collective experience with soon-to-be-minted graduates in the form of constructive feedback. “Senior Design is really one of the best days at Penn Engineering,” says Bradley Richards (C’92, LPS’17), Director of Alumni Relations, who manages the program. “Faculty advisors work with students all year long to bring out the best in each group’s efforts, and the results speak for themselves.”

This year, three student teams from each of Penn Engineering’s six departments — Bioengineering (BE), Chemical and Biomolecular Engineering (CBE), Computer and Information Science (CIS), Electrical and Systems Engineering (ESE), Materials Science and Engineering (MSE), and Mechanical Engineering and Applied Mechanics (MEAM)  — presented their work to more than 60 alumni in person and online.

Judges’ Choice Award

The Judges’ Choice Award, which recognizes overall excellence, went to ESE’s VivoDisk, which developed a novel machine to manufacture organs-on-a-chip for Vivodyne, a startup launched by Dan Huh, Associate Professor in BE.

As one of the team members, Akash Chauhan (ENG’24), learned while interning for Vivodyne, assembling the stacks of organs-on-a-chip, which are collections of plastic plates containing cells that simulate organs for preclinical drug testing, is extremely finicky and time consuming.

By developing a machine that could automatically align the plates with high precision using computer vision and AI, the team reduced the disks’ manufacturing time and expense, leading Vivodyne to adopt the device for commercial use, accelerating the process of drug discovery. VivoDisk’s team members included Chauhan; Angela Rodriguez (ENG’24), Aliris Tang (ENG’24, W’24), Dagny Lott (ENG’24), Simone Kwee (ENG’24) and Vraj Satashia (ENG’24, GEN’25) and was advised by Sid Deliwala, Alfred Moore Senior Fellow and Director of Lab Programs in ESE, and Jan Van der Spiegel, Professor in ESE.

Technology and Innovation Award

One of the greatest challenges for children with epilepsy is status epilepticus, an abnormal type of long-lasting seizure that is hard to distinguish from typical seizures and that has a mortality rate of 30%. There is currently no way to perform a test for status epilepticus at home, meaning that children suspected of having the condition must be rushed to the hospital for an electroencephalogram.

Epilog, a team from BE, developed a novel, wearable headset that analyzes brainwaves to accurately determine whether or not a child suffering a seizure is actually suffering from status epilepticus. The team, composed of Rohan Chhaya (ENG’24, GEN’24), Carly Flynn (ENG’24), Elena Grajales (ENG’24), Priya Shah (ENG’24, GEN’25) and Doris Xu (ENG’24) and advised by Erin Berlew, Research Scientist in the Department of Orthopaedic Surgery and Lecturer in BE, carefully validated the device’s accuracy.

The judges recognized Epilog’s technological expertise, which ran the gamut from software to hardware, including a custom app to work with the device and carefully considered features like electrodes whose position can be adjusted to accommodate a child’s growth over time.

2024 Solomon R. Pollack Awards for Excellence in Graduate Bioengineering Research

The Solomon R. Pollack Award for Excellence in Graduate Bioengineering Research is given annually to the most deserving Bioengineering graduate students who have successfully completed research that is original and recognized as being at the forefront of their field. This year, the Department of Bioengineering at the University of Pennsylvania is proud to recognize the work of four outstanding graduates in Bioengineering: William Benman, Alex Chan, Rohan Palanki and Sunghee Estelle Park. 

Read more about the 2024 Solomon R. Pollack awardees and their doctoral research below.

William Benman

Dissertation: “Remote control of cell function using heat and light as inputs”

Will conducts research in the lab of Lukasz Bugaj, Assistant Professor in Bioengineering, focusing on reprogramming cells so that their basic functions can be regulated artificially using heat and/or light as inputs. The goal of this work ranges from clinical applications, such as localized activation of cell therapies within patients via application of heat, to biological manufacturing, using light to activate production of valuable biologics during key phases of a cell’s life cycle. He earned his undergraduate degree in biomedical engineering from Boston University, where he graduated summa cum laude. At BU, he worked in the lab of Wilson Wong, where he was introduced to synthetic biology. During that time, he worked to develop a genetic logic framework that would allow cells to integrate chemical signals, such that each combination of signals would lead to a different, user-defined combination of genes being expressed. Outside of the lab, Benman enjoys baking and sharing his treats with lab members. He mentored the 2021 Penn iGEM team, which recently published their work in Communications Biology. After graduation, he will start a postdoctoral fellowship in Mikhail Shapiro’s lab at Caltech, where he plans to explore electrogenetics, focusing on how to co-opt electrically active cell types to transmit biochemical information out of the body. He is interested in researching ways to get cells to talk to electronic devices and vice/versa for two way communication, especially in the context of patient monitoring and precision therapies. 

“Will’s Ph.D. work broke new ground across several fields, discovering how certain proteins sense temperature, engineering those proteins for on-demand control of human cells, and building devices to allow us to communicate with cells with precision,” says Bugaj. “He has managed these accomplishments while elevating those around him through mentorship, including of graduate students, scores of undergraduates, and even grade-school students in the community. I am immensely proud of Will and what he has accomplished and am gratified by the recognition from the Sol Pollack award.”

Alex Chan

Dissertation: “Engineering small protein based inhibitors and biodegraders for cytosolic delivery and targeting of the undruggable proteome”

Alex conducts research in the lab of Andrew Tsourkas, Professor in Bioengineering and Co-Director, Center for Targeted Therapeutics and Translational Nanomedicine (CT3N). His research focuses on developing novel cancer therapeutics by engineering protein scaffolds so that they can be efficiently delivered into cells using lipid nanocarriers. These proteins can either behave as oncogenic inhibitors or be imbued with E3 domains for targeted protein degradation. He graduated from The Pennsylvania State University in 2018 with a B.S in Biomedical Engineering. There, he conducted undergraduate research on photo-activated silver nanoparticle miRNA delivery systems and wrote his senior honors thesis on this topic. At Penn, Alex served as a wellness co-chair within GABE (the Graduate Association of Bioengineers) and was awarded a graduate research fellowship program award by the National Science Foundation (NSF GRFP). In his spare time, Chan loves to cook and explore the local restaurant scene (and he thinks Philly is one of the most vibrant food meccas in America). Post-graduation, he plans to explore Asia before starting as a Senior Scientist in the biopharma industry. He intends to continue working on novel biologics-based medicines for unmet medical needs.

“I cannot think of anyone more deserving of this award than Alex,” says Tsourkas. “He not only demonstrates all of the traits that we love to see in our most successful Ph.D. students — intelligence, hard work ethic, and perseverance — but Alex has also exhibited a level of scientific independence that is beyond his years. I cannot wait to see what Alex achieves in the future.”

Rohan Palanki

Dissertation: “Ionizable lipid nanoparticles for in utero gene editing of congenital disease”

Rohan completed his B.S. in Bioengineering from Rice University in 2019 and subsequently matriculated into the Medical Scientist Training Program (M.D./Ph.D.) at the University of Pennsylvania. He conducted his doctoral research as an NIH Ruth L. Kirschstein Pre-Doctoral Fellow in the laboratories of Michael J. Mitchell, Associate Professor in Bioengineering, and William H. Peranteau, Associate Professor of Surgery at CHOP. After defending his thesis in 2024, he returned to medical school to complete his clinical training. He plans to pursue a career as a physician-engineer, conducting translational research at the intersection of biomaterials and genomic medicine. Outside of the lab, Palanki enjoys exploring new restaurants in Philadelphia and cheering on Philadelphia sports teams.

“Rohan pioneered new lipid nanoparticle gene editing technology in the lab that can treat deadly childhood diseases before a child is ever born,” says Mitchell. “Rohan is extremely deserving of this award, and I cannot wait to see what he accomplishes as a physician scientist developing new biomaterial and drug delivery technologies for pediatric applications.”

Sunghee Estelle Park

Dissertation: “Engineering stem cells and organoids on a chip for the study of human health and disease”

Sunghee Estelle Park earned her BMSE and MSME from Korea University and her Ph.D. in Bioengineering at the University of Pennsylvania, graduating in July 2023. She conducted doctoral research in the BIOLines Lab of Dan Huh, Associate Professor in Bioengineering. Her Ph.D. research combined principles in developmental biology, stem cell biology, organoids, and organ-on-a-chip technology to develop innovative in vitro models that can faithfully replicate the pathophysiology of various human diseases. Her doctoral dissertation presented engineering approaches to create stem cell derived three-dimensional (3D) miniature models of human organs on a chip that mimic the physiology and function of living human tissues. Park was appointed Assistant Professor of Biomedical Engineering in the Weldon School of Biomedical Engineering at Purdue University beginning January 2024. Her research lab focuses on using engineered tissues and organoid models to understand how biomechanical and biochemical cues direct stem cell differentiation, maturation, and function during development and disease progression, with a particular emphasis on the lung and intestine. 

“With her deep knowledge, extensive experience, and leadership, Estelle led the major undertaking of harnessing the power of microengineering technologies to create more in vivo-like culture environments in my group, and she played a central role in demonstrating the proof-of-concept of generating organoid-based in vitro models that enable new capabilities for studying complex human diseases and developing new therapeutics,” says Huh. “I am extremely proud of her tremendous accomplishments as a trailblazer in this emerging area and have every confidence that her work as an independent investigator will continue to make great contributions to advancing the field.”

Building Tiny Organs

by David Levin

Dan Huh, Ph.D. (Photo credit: Leslie Barbaro)

More than 34 million Americans suffer from pulmonary diseases like asthma, emphysema and chronic bronchitis. While medical treatments can keep these ailments in check, there are currently no cures. Part of the reason, notes Dan Huh, is that it’s incredibly hard to study how these diseases actually work. While researchers can grow cells taken from human lungs in a dish, they cannot expect them to act like they would in the body. In order to mimic the real deal, it’s necessary to recreate the complex, 3D environment of the lung — right down to its tiny air sacs and blood vessels — and to gently stretch and release the tissue to simulate breathing.

Huh, Associate Professor in Bioengineering, is the cofounder of Vivodyne, a Penn Engineering biotech spinoff that is creating tissues like these in the lab. Vivodyne uses a bioengineering technology that Huh has been developing for more than a decade. While a postdoctoral fellow at Harvard’s Wyss Institute, he played a central role in creating a novel device called an “organ on a chip,” which, as the name implies, assembles multiple cell types on a tiny piece of engineered plastic to create an approximation of an organ.

“While those chips represented a major innovation,” says Huh, “they still weren’t truly lifelike. They lacked many of the essential features of their counterparts in the human body, such as the network of blood vessels running between different kinds of tissue, which are essential for transporting oxygen, nutrients, waste products and various biochemical signals.”

Penn Partners in Multi-University Research Center Supporting Healthy Pregnancies

by Andrew Smith

How does the placenta keep harmful substances away from developing babies while still providing proper nutrition?

The exact mechanisms remain unknown, which is why the University of Pennsylvania, Rutgers University, Tulane University, the University of North Carolina at Chapel Hill and the University of Rochester have joined together to launch a research center dedicated to solving this mystery and ensuring healthy pregnancies.

A $5 million grant from the National Institutes of Health (NIH) will help fund the Integrated Transporter Elucidation Center (InTEC), which will operate from the Rutgers Biomedical Health Sciences campus in Piscataway under the leadership of Lauren Aleksunes, a professor of pharmacology and toxicology at Rutgers’ Ernest Mario School of Pharmacy and resident scientist in the Environmental and Occupational Health Sciences Institute (EOHSI).

“Since my time working as a community pharmacist, I have found the lack of high-quality information about the safety of everyday products on the health of a pregnancy frustrating,” says Aleksunes.  “People need to know whether the chemicals in their diet, personal care products and medications can impact their babies. Our goal at InTEC is to better understand how these chemicals travel in and out of the placenta and if they can reach the baby and influence their development.”

Aleksunes will study how transporter proteins carrying nutrients, dietary supplements, medications and toxic chemicals work during pregnancies. Some of the work will test how individual placenta cells respond to various stimuli in the laboratory. Others on the team will examine how environmental factors influence placental transporters during healthy and unhealthy or complicated pregnancies. 

Key to this work will be Dan Huh, Associate Professor in Bioengineering in Penn Engineering, who will lead a team with an innovative approach to modeling the transfer of molecules across the human placenta. 

As a pioneer of organ-on-a-chip technology, the Huh group will use a novel microengineered system in which maternal tissue engineered from a layer of primary human trophoblasts is grown adjacent to a three-dimensional network of perfusable fetal blood vessels to mimic the human placental barrier. This microphysiological system will be employed as an in vitro platform to simulate and quantitatively analyze the exchange of various substances between maternal and fetal circulation without the need for laboratory animals or placenta explants.

Estelle Sunghee Park Appointed Assistant Professor at Purdue University

Estelle Park, Ph.D.

Penn Bioengineering is proud to congratulate Sunghee Estelle Park, Ph.D. on her appointment as Assistant Professor in the Weldon School of Biomedical Engineering at Purdue University. Park earned her Ph.D. at Penn Bioengineering, graduating in July 2023. She conducted doctoral research in the BIOLines Lab of Dan Huh, Associate Professor in Bioengineering. Her appointment at Purdue will begin January 2024.

During her Ph.D. research, Park forged a unique path that combined principles in developmental biology, stem cell biology, organoids, and organ-on-a-chip technology to develop innovative in vitro models that can faithfully replicate the pathophysiology of various human diseases. Using a microengineered model of the human retina, she discovered previously unknown roles of the MAPK, IL-17, PI3K-AKT, and TGF-β signaling pathways in the pathogenesis of age-related macular degeneration (AMD), presenting novel therapeutic targets that could be further investigated for the development of AMD treatments. More recently, she tackled a significant challenge in the organoid field, the limited tissue growth and maturity in conventional organoid cultures, by designing microengineered systems that enabled organoids to grow with unprecedented levels of maturity and human-relevance. By integrating these platforms with bioinformatics and computational analyses, she identified novel disease-specific biomarkers of inflammatory bowel disease (IBD) and intestinal fibrosis, including previously unknown link between the presence of lncRNA and the development of IBD.

“The unique interdisciplinary expertise I gained from these projects has shaped me into a scholar with a strong collaborative ethos, a quality I hold in high esteem as we work towards advancing our knowledge and management of health and disease,” says Park.

Her vision as an independent researcher is to become a leading faculty who makes impactful contributions to our fundamental understanding of the factors influencing the structural and functional changes of human organs in health and disease. To achieve this, she plans to lead a stem cell bioengineering laboratory with a primary focus on tissue engineering and regenerative medicine. This will involve developing human organoids-on-a-chip systems and establishing next-generation biomedical devices and therapies tailored for regenerative and personalized medicine.

“I am grateful to all my Ph.D. mentors and lab mates at the BIOLines lab and especially my advisor Dr. Dan Huh, for his exceptional guidance, unwavering support, and invaluable mentorship throughout my Ph.D. journey,” says Park. “Dan’s expertise, dedication, and commitment to excellence have been instrumental in shaping both my research and professional development, while also training me to become an independent scientist and mentor.”

Congratulations to Dr. Park from everyone at Penn Bioengineering!

OCTOPUS, an Optimized Device for Growing Mini-Organs in a Dish

by Devorah Fischler

With OCTOPUS, Dan Huh’s team has significantly advanced the frontiers of organoid research, providing a platform superior to conventional gel droplets. OCTOPUS splits the soft hydrogel culture material into a tentacled geometry. The thin, radial culture chambers sit on a circular disk the size of a U.S. quarter, allowing organoids to advance to an unprecedented degree of maturity.

When it comes to human bodies, there is no such thing as typical. Variation is the rule. In recent years, the biological sciences have increased their focus on exploring the poignant lack of norms between individuals, and medical and pharmaceutical researchers are asking questions about translating insights concerning biological variation into more precise and compassionate care.

What if therapies could be tailored to each patient? What would happen if we could predict an individual body’s response to a drug before trial-and-error treatment? Is it possible to understand the way a person’s disease begins and develops so we can know exactly how to cure it?

Dan Huh, Associate Professor in the Department of Bioengineering at the University of Pennsylvania’s School of Engineering and Applied Science, seeks answers to these questions by replicating biological systems outside of the body. These external copies of internal systems promise to boost drug efficacy while providing new levels of knowledge about patient health.

An innovator of organ-on-a-chip technology, or miniature copies of bodily systems stored in plastic devices no larger than a thumb drive, Huh has broadened his attention to engineering mini-organs in a dish using a patient’s own cells.

A recent study published in Nature Methods helmed by Huh introduces OCTOPUS, a device that nurtures organs-in-a-dish to unmatched levels of maturity. The study leaders include Estelle Park, doctoral student in Bioengineering, Tatiana Karakasheva, Associate Director of the Gastrointestinal Epithelium Modeling Program at Children’s Hospital of Philadelphia (CHOP), and Kathryn Hamilton, Assistant Professor of Pediatrics in Penn’s Perelman School of Medicine and Co-Director of the Gastrointestinal Epithelial Modeling Program at CHOP.

From left to right: Marc Singer, Kirsten Leute, D. Kacy Cullen, Dan Huh, Doug Smith, and Haig Aghajanian

Two Penn Bioengineering Professors have received awards in the 7th Annual Celebration of Innovation from the Penn Center for Innovation (PCI).

Dongeun (Dan) Huh, Associate Professor in the Department of Bioengineering, was named the 2022 Inventor of the Year. D. Kacy Cullen, Associate Professor of Neurosurgery with a secondary appointment in Bioengineering, accepted the Deal of the Year Award on behalf of his company Innervace along with Co-Scientific Founder Douglas H. Smith, Robert A. Groff Professor of Teaching and Research in Neurosurgery in the Perelman School of Medicine.

PCI is interdisciplinary center for technology commercialization and startups in the Penn community. Their 7th Annual Celebration, held on December 6, 2022 at the Singh Center for Nanotechnology, honored Penn researchers and inventors whose achievements were a particular highlight of the fiscal year.

Huh was honored in recognition of his “extraordinary innovations in bioengineering tools.” The Huh Biologically Inspired Engineering Systems Laboratory (BIOLines) Laboratory is a leader in tissue engineering and cell-based smart biomedical devices, particularly in the “lab-on-a-chip” field of devices which can approximate the functioning of organs. Their research has been featured by the National Science Foundation (NSF, video below) and Wired, and has received a competitive Chan Zuckerberg Initiative (CZI) grant. Most recently, their “implantation-on-a-chip” technology has been used to better understand early-stage pregnancy. Huh and former lab member Andrei Georgescu (Ph.D. in Bioengineering, 2021) founded the spinoff company Vivodyne to bring this organ-on-a-chip technology to the industry sector. Fast Company included Vivodyne in a list of “most innovative” companies.

Innervace, represented by Cullen and Smith, took home the Deal of the Year award in recognition of its “successful Series A funding.” Innervace is another Penn spinoff which develops “anatomically inspired living scaffolds for brain pathway reconstruction.” Innervace raised up to $40 million in Series A financing to “accelerate a new cell therapy modality for the treatment of neurological disorders.” The Cullen Lab at Penn Medicine combines neuroengineering, regenerative medicine, and the study of neurotrauma to improve understanding of neural injury and develop cutting-edge neural tissue engineering-based treatments to promote regeneration and restore function.

‘Organ-on-a-Chip’ Device Provides New Insights into Early-Stage Pregnancy

by Scott Harris

Dan Huh’s BIOLines Lab develops several different kinds of organ-on-a-chip systems, such as this blinking-eye-on-a-chip.

If you’d read about it in a science fiction novel, you might not have believed it. Human organs and organ systems — from lungs to blood vessels to blinking eyes — bio-miniaturized and stored on a plastic chip no larger than a matchbook.

But that’s the breathing, blinking reality at the Biologically Inspired Engineering Systems (BIOLines) Laboratory in the Department of Bioengineering in the School of Engineering and Applied Sciences at the University of Pennsylvania, a bona fide pioneer of what is now widely known as “organ-on-a-chip” technology. Proponents hope these devices can one day help scientists around the world learn more about the body’s inner workings and ultimately improve disease prevention and treatment.

“The century-old practice of cell culture is to grow living cells isolated from the human body in hard plastic dishes and keep them bathed in copious amounts of culture media under static conditions, and that is drastically different than the complex, dynamic environment of native tissues in which these cell reside,” said Dan Dongeun Huh, Ph.D., BIOLines’ principal investigator and an associate professor of Bioengineering in Penn’s School of Engineering and Applied Science. “What makes this organ-on-a-chip technology so unique and powerful is that it enables us to reverse-engineer living human tissues using microengineered devices and mimic their intricate biological interactions and physiological functions in ways that have not been possible using traditional cell culture techniques. This represents a major advance in our ability to model and understand the inner workings of complex physiological systems in the human body.”

Generally speaking, organ-on-a-chip devices are made of clear silicone rubber — the same material used to make contact lenses — and can vary in size and design. Embedded within are microfabricated three-dimensional chambers lined with different human cell types, arranged and propagated to ultimately form a structure complex enough to actually mimic the essential elements of a functioning organ.

With partners at the Perelman School of Medicine, BIOLines recently developed a newer variation of the organ-on-a-chip: one that replicates the interface between maternal tissue and the cells of the placenta at the critical moments in early pregnancy when the embryo is implanting in the uterus. Huh and Penn Medicine physicians led a study using the “implantation-on-a-chip” to observe things that would otherwise have been virtually unobservable.

The study findings appeared this spring in the journal Nature Communications.

Bionegineering Spin-off Vivodyne on Fast Company’s ‘Most Innovative’ List

Andrei Georgescu (left) and Dan Huh developed several organ-on-a-chip platforms in Huh’s lab. Their spin-off company, Vivodyne, aims to use the technology as a scalable alternative to animal testing in the pharmaceutical industry.

With Vivodyne, Associate Professor in the Department of Bioengineering Dan Huh is translating the organs-on-chips technology into a promising industry venture. Using microfluidic structures that mimic aspects of human physiology, organs-on-chips allow scientists to test therapies on lab-grown human cells. Vivodyne specifically focuses on designing organs-on-chips to create a scalable alternative for pharmaceutical drug testing on animals.

Last year, the company raised $4 million dollars in seed money. This year, it’s topping influential lists of small companies making big impacts.

Fast Company now lists it as one of “the 10 most innovative companies with fewer than 10 employees,”  saying “Vivodyne is helping major pharmaceutical companies like GlaxoSmithKline quickly adopt viable alternatives for testing drugs on monkeys.”

Vivodyne, launched in 2021, has created a platform that allows fully automated, complex studies at a far larger scale and lower cost than would be possible with manual experimentation, so pharmaceutical companies can actually test lab-made organs instead of animals in their drug-development processes. When done by hand, only 20 to 40 living tissue samples can be managed in parallel; Vivodyne’s instrument can cultivate, dose, and image more than 2,000 living tissues at once. The company, which raised $4 million in seed funding last year, says its instruments currently play pivotal roles in clinical drug testing for respiratory diseases, cancer treatment, vaccine development, diabetes therapies, and maternal medicine. GlaxoSmithKline, one of Vivodyne’s clients, estimates that for some projects the lab-grown tissues may displace as much as 80% of its animal testing. The company’s ultimate goal? “To supplant the vast majority of animal testing within the next decade,” says CEO Andrei Georgescu.
