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.”

2024 Penn Bioengineering Senior Design Projects Advance to Interdepartmental Competition

On April 17, 2024, the Department of Bioengineering held its annual Bioengineering (BE) Senior Design Presentations in the Singh Center for Nanotechnology, followed by a Design Expo in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace.

A panel of expert and alumni judges chose 3 teams to advance to the School-wide, interdepartmental competition, to be held on May 3, 2024.

Team ADONA: Jude Barakat, Allison Elliott, Daniel Ghaderi, Aditi Ghalsasi, Taehwan Kim

ADONA (A Device for the Assisted Detection of Neonatal Asphyxia)

Hypoxic-ischemic encephalopathy (HIE) is a condition that arises from inadequate oxygen delivery or blood flow to the brain around the time of birth, resulting in long-term neurological damage. This birth complication is responsible for up to 23% of neonatal deaths worldwide. While effective treatments exist, current diagnostic methods require specialized neurologists to analyze an infant’s electroencephalography (EEG) signal, requiring significant time and labor. In areas where such resources and specialized training are even scarcer, the challenges are even more pronounced, leading to delayed or lack of treatment, and poorer patient outcomes. The Assisted Detection of Neonatal Asphyxia (ADONA) device is a non-invasive screening tool that streamlines the detection of HIE. ADONA is an EEG helmet that collects, wirelessly transmits, and automatically classifies EEG data using a proprietary machine learning algorithm in under two minutes. Our device is low-cost, automated, user-friendly, and maintains the accuracy and reliability of a trained neurologist. Our classification algorithm was trained using 1100 hours of annotated clinical data and achieved >85% specificity and >90% sensitivity on an independent 200 hour dataset. Our device is now produced in Agilus 30, a flexible and tear resistant material, that reduces form factor and ensures regulatory compliance. For our final prototype, we hope to improve electrode contact and integrate software with clinical requirements. Our hope is that ADONA will turn the promise of a safer birth into a reality, ensuring instant peace of mind and equitable access to healthcare, for every child and their families.

Team Epilog: Rohan Chhaya, Carly Flynn, Elena Grajales, Priya Shah, Dori Xu

Epilog

To address the critical need for effective, at-home seizure monitoring in pediatric neurology, particularly for Status Epilepticus (SE), our team developed Epilog: a rapid-application electroencephalography (EEG) headband. SE is a medical emergency characterized by prolonged or successive seizures and often presents with symptoms too subtle to notice or easily misinterpreted as post-convulsive fatigue. This leads to delayed treatment and increased risks of neurological damage and high mortality. Current seizure detection technologies are primarily based on motion or full-head EEG, rendering them ineffective at detecting SE and impractical for at-home use in emergency scenarios, respectively. Our device is designed to be applied rapidly during the comedown of a convulsive seizure, collect EEG data, and feed it into our custom machine learning algorithm. The algorithm processes this data in real-time and alerts caregivers if the child remains in SE, thereby facilitating immediate medical decision-making. Currently, Epilog maintains a specificity of 0.88 and sensitivity of 0.95, delivering decisions within 15 seconds post-seizure. We have demonstrated clean EEG signal acquisition from eight standard electrode placements and bluetooth data transmission from eight channels with minimal delay. Our headband incorporates all necessary electrodes and adjustable positioning of the electrodes for different head sizes. Our unique gel case facilitates rapid electrode gelation in less than 10 seconds. Our most immediate goals are validating our fully integrated device and improving features that allow for robust, long-term use of Epilog. Epilog promises not just data, but peace of mind, and empowering caregivers to make informed life-saving decisions.

Team NG-LOOP: Katherine Han, Jeffrey Huang, Dahin Song, Stephanie Yoon

NG-LOOP

Nasogastric (NG) tube dislodgement occurs when the feeding tube tip becomes significantly displaced from its intended position in the stomach, causing fatal consequences such as aspiration pneumonia. Compared to the 50% dislodgement rate in the general patient population, infant patients are particularly affected ( >60%) due to their miniature anatomy and tendency to unknowingly tug on uncomfortable tubes. Our solution, the Nasogastric Lightweight Observation and Oversight Product (NG-LOOP) provides comprehensive protection from NG tube dislodgement. Physical stabilization is combined with sensor feedback to detect and manage downstream complications of tube dislodgement. The lightweight external bridle, printed with biocompatible Accura 25 and coated with hydrocolloid dressing for comfort and grip, can prevent dislodgement 100% of the time given a tonic force of 200g. The sensor feedback system uses a DRV5055 linear hall effect sensor with a preset difference threshold, coupled with an SMS alert and smart plug inactivation of the feeding pump. A sensitivity of 90% and specificity of 100% in dislodgement detection was achieved under various conditions, with all feedback mechanisms being initiated in response to 100% of threshold triggers. Future steps involve integration with hospital-grade feeding pumps, improving the user interface, and incorporating more sizes for diverse age inclusivity.

2023 PIP-Winning Team Sonura: Where Are They Now?

Members of Team Sonura: Tifara Boyce, Gabriela Cano, Gabriella Daltoso, Sophie Ishiwari, & Caroline Magro (credit: Penn BE Labs)

In April 2023, three President’s Prize-winning teams were selected from an application pool of 76 to develop post-graduation projects that make a positive, lasting difference in the world. Each project received $100,000 and a $50,000 living stipend per team member.

The winning projects include Sonura, the winner of the President’s Innovation Prize (PIP), who are working to improve infant development by reducing harsh noise exposure in neonatal intensive care units. To accomplish this, they’ve developed a noise-shielding beanie that can also relay audio messages from parents.

Sonura, a bioengineering quintet, developed a beanie that shields newborns from the harsh noise environments present in neonatal intensive care units (NICUs)—a known threat to infant wellbeing—and also supports cognitive development by relaying audio messages from their parents.

Since graduating from the School of Engineering and Applied Science, the team of Tifara Boyce, Gabriela Cano, Gabriella Daltoso, Sophie Ishiwari, and Caroline Magro, has collaborated with more than 50 NICU teams nationwide. They have been helped by the Intensive Care Nursery (ICN) at the Hospital of the University of Pennsylvania (HUP), which shares Sonura’s goal of reducing NICU noise. “Infant development is at the center of all activities within the HUP ICN,” note Daltoso and Ishiwari. “Even at the most granular level, like how each trash can has a sign urging you to shut it quietly, commitment to care is evident, a core tenet we strive to embody as we continue to grow.” 

An initial challenge for the team was the inability to access the NICU, crucial for understanding how the beanie integrates with existing workflows. Collaboration with the HUP clinical team was key, as feedback from a range of NICU professionals has helped them refine their prototype.

In the past year, the team has participated in the University of Toronto’s Creative Destruction Lab and the Venture Initiation Program at Penn’s Venture Lab, and received funding from the Pennsylvania Pediatric Device Consortium. “These experiences have greatly expanded our perspective,” Cano says.

With regular communication with mentors from Penn Engineering and physicians from HUP, Children’s Hospital of Philadelphia, and other institutes, Sonura is looking ahead as they approach the milestone of completing the FDA’s regulatory clearance process within the year. They will begin piloting their beanie with the backing of NICU teams, further contributing to neonatal care.

Riccardo Gottardi Recognized for Airway Research

Matthew Aronson (left), Ph.D. student in Bioengineering, and Riccardo Gottardi, Assistant Proessor in Bioengineering and Pediatrics.

Riccardo Gottardi, Assistant Professor in Pediatrics in the Perelman School of Medicine and in Bioengineering in the School of Engineering and Applied Science, has been named a “Young Innovator of Cellular and Molecular Bioengineering” by Cellular and Molecular Bioengineering, the official journal of the Biomedical Engineering Society (BMES). Gottardi is Chief Scientist in the Pediatric Airway Frontier Program at the Children’s Hospital of Philadelphia (CHOP). He leads the Bioengineering and Biomaterials (Bio2) Lab, and was recognized here for his research to prevent subglottic stenosis in children.

Gottardi’s work in subglottic stensosis, a severe narrowing of the airway in response to intubation, was recently profiled in CHOP’s Cornerstone Blog. CHOP’s award press release describes Gottardi’s innovative treatment:

“Prior studies by Dr. Gottardi’s lab used in vitro models to demonstrate that incorporating AMPs into polymer-coated tubes can inhibit bacterial growth and modulate the upper-airway microbiome. In a recent study in Cellular and Molecular Engineering, led by [Bioengineering] PhD student Matthew Aronson of the Gottardi Lab, the researchers went a step further and used both ex vivo and in vivo models to show how their patent-pending antimicrobial peptide-eluting endotracheal tube (AMP-ET) effectively targeted the local airway microbiota, reducing inflammation and resolving stenosis.

‘I am honored to be recognized by Cellular and Molecular Engineering for this exciting and notable award,” Dr. Gottardi said. “We are hopeful that our airway innovation will show similar success in human trials, so that we can improve outcomes for intubated pediatric patients.’”

Penn Bioengineers Create Non-invasive Cartilage Implants for Pediatric Subglottic Stenosis

by Emily Shafer

Paul Gehret and Riccardo Gottardi accept the International Society for Biofabrication New Investigator Award onstage at the international conference.
Paul Gehret (left) and Riccardo Gottardi, PhD, at Biofabrication 2022, the International Conference on Biofabrication.

Bioengineering researchers at Children’s Hospital of Philadelphia are developing a less invasive and quicker method to create cartilage implants as an alternative to the current treatment for severe subglottic stenosis, which occurs in 10 percent of premature infants in the U.S.

Subglottic stenosis is a narrowing of the airway, in response to intubation. Severe cases require laryngotracheal reconstruction that involves grafting cartilage from the rib cage with an invasive surgery. With grant support from the National Institutes of Health, Riccardo Gottardi, PhD, who leads the Bioengineering and Biomaterials (Bio2) Lab at CHOP, is refining a technology called Meniscal Decellularized scaffold (MEND). Working with a porcine model meniscus, the researchers remove blood vessels and elastin fibers to create pathways that allow for recellularization. Dr. Gottardi and his team then harvest ear cartilage progenitor cells (CPCs) with a minimally invasive biopsy, combine them with MEND, and create cartilage implants that could be a substitute for the standard laryngotracheal reconstruction.

This work and similar work on the tympanic membrane earned Paul Gehret, a doctoral student in the Gottardi Lab, the International Society for Biofabrication New Investigator Award and the Wake Forest Institute for Regenerative Medicine Young Investigator Award.  Gehret and Dr. Gottardi accepted the awards at Biofabrication 2022, the International Conference on Biofabrication, in Pisa Italy.

While laryngotracheal reconstruction in the adult population has a success rate of up to 96%, success rates in children range from 75% to 85%, and children often require revision surgery due to a high incidence of restenosis. The procedure also involves major surgery to remove cartilage from the rib cage, which is more difficult for childrens’ smaller bodies.

“Luckily not many children suffer from severe subglottic stenosis, but for those who do, it is really serious,” said Dr. Gottardi, who also is assistant professor in the Department of Pediatrics and Department of Bioengineering at CHOP and the University of Pennsylvania. “With our procedure, we have an easily accessible source for the cartilage and the cells, providing a straightforward and noninvasive treatment option with much potential.”
