The first few waves of COVID-19 slowed life across the United States, affecting everything from attending school to eating out for dinner and going on vacation. Segments of health care were also affected: Services that were not considered immediately crucial to fighting the virus were slowed or stopped during the pandemic’s first wave.
But once Penn Medicine invited patients back to resume normal health care—including preventive care, like screenings for disease—there was some lag in numbers.
“As we opened up to routine outpatient care, screening rates for situations when patients didn’t have symptoms were not returning back to normal,” said Mitchell Schnall, MD, PhD, FACR, a professor of Radiology, now the senior vice president for Data and Technology Solutions at Penn Medicine, and then the head of a team focused on the “resurgence” efforts to ease patients back into outpatient care. “Although a short delay in health screening is likely not going to cause long-term health problems, we were concerned whether screening rates would stay lower and lead to a long-term impact.”
Ongoing clinical trials have demonstrated that psychedelics like psilocybin and LSD can have rapid and long-lived antidepressant and anti-anxiety effects. A related clinical problem is chronic pain, which is notoriously difficult to treat and often associated with depression and anxiety.
This summer, Ahmad Hammo, a rising third-year student in bioengineering in the School of Engineering and Applied Science, is conducting a pilot study to explore psilocybin’s potential as a therapy for chronic pain and the depression that often accompanies it.
“There’s a strong correlation between chronic pain and depression, so I’m looking at how a psychedelic might be used for treating both of these things simultaneously,” says Hammo, who is originally from Amman, Jordan.
Hammo’s project focuses on neuropathic pain, pain associated with nerve damage. Like other forms of chronic pain, most experts believe that chronic neuropathic pain is stored in the brain.
“Neuropathic pain can lead to a centralized pain syndrome where the pain is still being processed in the brain,” Cichon says. “It’s as if there’s a loop that keeps playing over and over again, and this chronic form is completely divorced from that initial injury.”
William Danon and Luka Yancopoulos, winners of the 2022 President’s Innovation Prize, will offer a software solution to make the health care supply chain more efficient.
by Brandon Baker
William Danon and Luka Yancopoulos pose in front of College Hall in April 2022. They are co-founders of Grapevine and the winners of the 2022 President’s Innovation Prize.
William Danon and Luka Yancopoulos are best friends. They’re also business partners.
The duo, who received this year’s President’s Innovation Prize (PIP) for Grapevine, met during sophomore year, connected through Yancopoulos’ roommate. As time went on, they did everything together: cooked meals, played basketball, and read and discussed fantasy novels.
“We spent a lot of time together,” Danon says.
It was only natural, then, that when the time came to start an actual venture, they’d do it together.
“They’re like brothers, in a very good way,” says mentor David Meaney of the School of Engineering and Applied Science, who describes their working dynamic as “complementary.” “I think that will serve them well. Most of what we do in faculty is collaborative, and I see elements of that in their partnership. I give them credit for stepping out and doing something unusual and keeping at it.”
How Grapevine came to be
Grapevine is a software solution and professional networking platform that connects small-to-medium-size players in the health care supply chain. It’s a sort of two-pronged solution: It helps institutions like hospital systems connect disjointed operations like procurement and inventory management internally, but also serves as a glue between these institutions and purveyors of medical equipment.
“William and Luka are impact-driven entrepreneurs whose collaborative synergies will take them far,” says Penn Interim President Wendell Pritchett. “The software provided by Grapevine is poised to reinvent how the health care industry buys and sells medical supplies and services and, truly, could not come at a timelier moment.”
The company is the evolution of a project they began at the onset of the COVID-19 pandemic, called Pandemic Relief Supply, which delivered $20 million of health care supplies to frontline workers.
“My mom was a nurse practitioner at New York Presbyterian Hospital, the largest hospital in the United States, and she was coming home with horror stories,” recalls Yancopoulos. “In surgery or the ER, a surgeon had to put on a garbage bag because they didn’t have a gown. And they gave her one mask to use for the rest of the month, and I’m seeing on the news, ‘Don’t wear a mask for more than three days.’”
This is where Yancopoulos and Danon first developed an interest in the health care supply chain. Using a database Penn allows students access to that maps the import of any good in the country, they did keyword matching to identify instreams of different goods and handed off findings to New York Presbyterian procurement staff. When McKesson, the largest provider of health care products and services in the U.S., took notice of what they were doing and reached out, they realized they were onto something. In response to their success, they started a company called Pandemic Relief Supply to distribute reliable medical supplies, including items like medical-grade masks and gloves, to frontline workers in the healthcare space.
As time passed, that project evolved into something larger: Grapevine.

In short, Grapevine’s software creates a professional networking platform to resolve miscommunications between suppliers and buyers, as well as adds a layer of transparency between interactants. Suppliers on the platform display real-time data about their inventory and shipping process, with timestamps; this prohibits companies from cherry-picking data or making false claims and creates a more health-care-supply-specific space for companies to interact than, say, LinkedIn.
“Primarily, the first step is we want people to use it internally, and streamline operations, and then through that centralized operational data, you can push that externally and that’s where [Grapevine] becomes a connector,” explains Danon. “Because when you’re choosing to connect with someone, the reason you can do so way more efficiently or quickly, is that data is actual operational data.”
To accomplish this level of transparency, the beginnings of Grapevine involved lots of legwork. Last year, the duo moved to Los Angeles to take stock of what suppliers existed where, and how reliable they were. They realized that many suppliers existed around Los Angeles because of port access; many medical supplies are imported from Asia. Their time in LA made the problem feel even more tangible, they agree.
“We were able to see people were doing outdated processes—manual processes—because there’s no other option,” Danon says. “So, we said, ‘Let’s get out there and do some work to be digital and technologically innovative.”

Joseph Lance Casila, a doctoral student and Fontaine Fellow in Bioengineering, was profiled by his alma mater, the University of Guam (UOG. Casila was the first person in his family to graduate from a U.S.-accredited university and is now studying tissue engineering and regenerative medicine in the Bioengineering and Biomaterials Laboratory of Riccardo Gottardi, Assistant Professor in Bioengineering in Penn Engineering and Pediatrics in Penn Medicine and the Children’s Hospital of Philadelphia (CHOP). His research in the Gottardi lab employs “tissue engineering and drug delivery for biomedical problems relating to knees, ears, nose, and throat but specifically to pediatric airway disorders.” The article discusses Casila’s journey from valedictorian of his high school, to a first-generation undergraduate interested bioengineering, and now a graduate student studying at Penn on a full scholarship. After completing his degree, Casila hopes to bring what he’s learned back home to advance health care in Guam.
“My mentors, and especially my friends, helped me make the most of what UOG had to offer, and it paid off rewardingly,” he said. “You get what you put in.”

The University of Pennsylvania announced today that it has made a $100 million commitment in its School of Engineering and Applied Science to establish the Center for Precision Engineering for Health.
The Center will conduct interdisciplinary, fundamental, and translational research in the synthesis of novel biomolecules and new polymers to develop innovative approaches to design complex three dimensional structures from these new materials to sense, understand, and direct biological function.
“Biomaterials represent the ‘stealth technology’ which will create breakthroughs in improving health care and saving lives,” says Penn President Amy Gutmann. “Innovation that combines precision engineering and design with a fundamental understanding of cell behavior has the potential to have an extraordinary impact in medicine and on society. Penn is already well established as an international leader in innovative health care and engineering, and this new Center will generate even more progress to benefit people worldwide.”
Penn Engineering will hire five new President’s Penn Compact Distinguished Professors, as well as five additional junior faculty with fully funded faculty positions that are central to the Center’s mission. New state-of-the-art labs will provide the infrastructure for the research. The Center will seed grants for early-stage projects to foster advances in interdisciplinary research across engineering and medicine that can then be parlayed into competitive grant proposals.
“Engineering solutions to problems within human health is one of the grand challenges of the discipline,” says Vijay Kumar, Nemirovsky Family Dean of Penn Engineering. “Our faculty are already leading the charge against these challenges, and the Center will take them to new heights.”
This investment represents a turning point in Penn’s ability to bring creative, bio-inspired approaches to engineer novel behaviors at the molecular, cellular, and tissue levels, using biotic and abiotic matter to improve the understanding of the human body and to develop new therapeutics and clinical breakthroughs. It will catalyze integrated approaches to the modeling and computational design of building blocks of peptides, proteins, and polymers; the synthesis, processing, and fabrication of novel materials; and the experimental characterizations that are needed to refine approaches to design, processing, and synthesis.
“This exciting new initiative,” says Interim Provost Beth Winkelstein, “brings together the essential work of Penn Engineering with fields across our campus, especially in the Perelman School of Medicine. It positions Penn for global leadership at the convergence of materials science and biomedical engineering with innovative new techniques of simulation, synthesis, assembly, and experimentation.”
Examples of the types of work being done in this field include new nanoparticle technologies to improve storage and distribution of vaccines, such as the COVID-19 mRNA vaccines; the development of protocells, which are synthetic cells that can be engineered to do a variety of tasks, including adhering to surfaces or releasing drugs; and vesicle based liquid biopsy for diagnosing cancer.

With the shared vision to transform the future of oral health care, Penn Dental Medicine and Penn’s School of Engineering and Applied Sciences have united to form the Center for Innovation & Precision Dentistry (CiPD). The new Center marked its official launch on January 22 with a virtual program celebrating the goals and plans of this unique partnership. Along with the Deans from both schools, the event gathered partners from throughout the University of Pennsylvania and invited guests, including the National Institute of Dental and Craniofacial Research Director (NIDCR) Dr. Rena D’Souza and IADR Executive Director Chris Fox.
Conceived and brought to fruition by co-directors Dr. Michel Koo of Penn Dental Medicine and Dr. Kathleen Stebe of Penn Engineering, the CiPD is bridging the two schools through cutting-edge research and technologies to accelerate the development of new solutions and devices to address unmet needs in oral health, particularly in the areas of dental caries, periodontal disease, and head and neck cancer. The CiPD will also place a high priority on programs to train the next generation of leaders in oral health care innovation.
“We have a tremendous global health challenge. Oral diseases and craniofacial disorders affect 3.5 billion people, disproportionately affecting the poor and the medically and physically compromised,” says Dr. Koo, Professor in the Department of Orthodontics and Divisions of Community Oral Health and Pediatric Dentistry, in describing their motivation to form the Center. “There is an urgent need to find better ways to diagnose, prevent, and treat these conditions, particularly in ways that are affordable and accessible for the most susceptible populations. That is our driving force for putting this Center together.”
“We have united our schools around this mission,” adds Dr. Stebe, Richer & Elizabeth Goodwin Professor in the Department of Chemical and Biomolecular Engineering. “We have formed a community of scholars to develop and harness new engineering paradigms, to generate new knowledge, and to seek new approaches that are more effective, precise, and affordable to address oral health. More importantly, we will train a new community of scholars to impact this space.”
Born through Interdisciplinary Research
A serendipitous connection born through Penn’s interdisciplinary research environment itself brought Drs. Koo and Stebe together more than five years ago, an introduction that would eventually lead to creating the CiPD.
Dr. Tagbo Niepa, now assistant professor at the University of Pittsburgh, came to Penn Engineering in 2014 as part of Penn’s Postdoctoral Fellowship for Academic Diversity, an initiative from the office of the Vice Provost for Research. His studies on the microbiome led him to reach out to Dr. Stebe and Dr. Daeyeon Lee (also at Penn Engineering), and to connect them to Dr. Koo, initiating collaboration between their labs.
“Tagbo embodies what we are trying to do with the CiPD,” recalls Dr. Stebe. “He had initiative, he identified new tools and important context, and he did good science that may help us understand how to interrupt the disease process and identify new underlying mechanisms that can inspire new therapies.” Dr. Niepa worked on applying microfluidics and engineering to study the oral microbiome and better understand how the interactions between fungi and bacteria could impact dental caries.
“Upon meeting Michel, we became excited about the possibilities of bringing talent from the two schools together,” notes Dr. Stebe. A 2018 workshop organized by Drs. Koo and Stebe and funded by Penn’s Vice Provost of Research explored the potential for expanding cross-school research. “We invited researchers from dental medicine and engineering as well as relevant people from the arts and sciences to see if we could find a way to collaborate to advance oral and craniofacial health,” says Dr. Koo. “That was the catalyst for the Center; after the workshop, we put together a task force which would become the core members of the CiPD.”
In addition to Drs. Koo and Stebe, the CiPD Executive Committee includes Associate Directors Dr. Henry Daniell, Vice-Chair and W.D. Miller Professor, Department of Basic & Translational Sciences, Penn Dental Medicine, and Dr. Anh Le, Chair and Norman Vine Endowed Professor of Oral Rehabilitation, Department of Oral and Maxillofacial Surgery / Pharmacology, Penn Dental Medicine; as well as Dr. Andrew Tsourkas, Professor, Department of Bioengineering, Co-Director, Center for Targeted Therapeutics & Translational Nanomedicine (CT3N) and Chemical and Nanoparticle Synthesis Core, Penn Engineering; and Dr. Jason Moore, Edward Rose Professor of Informatics, Director of the Penn Institute for Biomedical Informatics. The core members of CiPD include 26 faculty from across both Penn Dental Medicine and Penn Engineering, and also from the Schools of Medicine and Arts & Sciences.

Title: “Emerging Technologies for Detection of Early Stage Bladder Cancer”
Abstract:
Bladder cancer (BC) — the 4th most common cancer in men and the most expensive cancer to treat over a patient’s lifetime — is a lifelong burden to BC patients and a significant economic burden to the U.S. healthcare system. The high cost of BC stems largely from its high recurrence rate (>50%); hence, BC management involves frequent surveillance. Unfortunately, the current in-office standard-of-care tool for BC surveillance, white light cystoscopy (WLC), is limited by low sensitivity and specificity for carcinoma in situ (CIS), a high-grade carcinoma with high potential to metastasize. Early detection and complete eradication of CIS are critical to improve treatment outcomes and to minimize recurrence. The most promising macroscopic technique to improve sensitivity to CIS detection, blue light cystoscopy (BLC), is costly, time-intensive, has low availability and a high false-positive rate. Given the limitations of WLC, we aim to change the paradigm around how BC surveillance is performed by validating new tools with high sensitivity and specificity for CIS that are appropriate for in-office use. In this seminar, I discuss our innovative solutions to improve mapping the bladder for longitudinal tracking of suspicious lesions and to create miniature tools for optical detection based on optical coherence tomography (OCT). OCT and its functional variant, cross-polarized OCT, can detect early-stage BC with better sensitivity and specificity than WLC. We discuss the critical technical innovations necessary to make OCT and CP-OCT a practical tool for in-office use, and new results from recent explorations of human bladder samples that speak to the promise of this approach to change the management of patient care.

Title: “Patients, Providers and Data: How the EMR and Data Science are Changing Clinical Care”
Abstract:
The electronic health record (EHR) is a powerful application of Systems Engineering to healthcare. It is a byproduct of a host of pressures including cost, consolidation of providers into networks, uniform drivers of quality, and the need for timely care across disparate socioeconomic and geographic landscapes within health systems. The EHR is also a fulcrum for innovation and one of the most tangible examples of how data science affects our health and health care. In this talk I will showcase projects from my lab that demonstrate the multi-disciplinary nature of biomedical informatics/data science research and translation using the EHR, and our current understanding of its potential from my perspective as a pediatrician, a researcher in biomedical informatics, a Chief Information Officer, an educator, and an advisor to local and international policy. I will describe advances in applying human factors engineering to support medical documentation and generic prescribing, approaches to improve medication safety, and innovations to support precision medicine and interoperability. I will present our efforts to integrate EHR-enabled data science into the Vanderbilt health system and provide a vision for what this could mean for our future.
