Kevin Johnson is used to forging his own path in the fields of healthcare and computer science.
A picture of Johnson as a child, from his children’s book “I’m a Biomedical Expert Now!”
If you ask him to locate his niche within these fields, Johnson, David L. Cohen and Penn Integrates Knowledge (PIK) Professor with appointments in Penn Engineering and the Perelman School of Medicine, would say “informatics.” But that doesn’t tell the whole story of the board-certified pediatrician, who has dedicated his career to innovations in how patients’ information is created, documented and shared, all with the goal of improving the quality of healthcare they receive.
Informatics, the study of the structure and behavior of interactions between natural and computational systems, is an umbrella term. Within it, there’s bioinformatics, which applies informatics to biology, and biomedical informatics, which looks at those interactions in the context of healthcare systems. Finally, there is clinical informatics, which further focuses on the settings where healthcare is delivered, and where Johnson squarely places himself.
“But you can just call it ‘informatics,’” says Johnson. “It will be easier.”
He mainly studies how computational systems can improve ambulatory care — sometimes known as outpatient care, or the kind of care hospitals give to patients without admitting them — in real time. If you’ve ever heard your doctor complain about the amount of time it takes them to input the information they get from you during your visit, or wondered why they need to capture this information during the visit in the first place, these are some of the questions Johnson is investigating.
“We’re taking care of patients but we’re getting frustrated by things that we thought these new computers should be able to fix,” says Johnson.” I think there’s a very compelling case for using engineering principles to reimagine electronic health records.”
Kevin Johnson is the David L. Cohen University of Pennsylvania Professor in the Departments of Biostatistics, Epidemiology and Informatics and Computer and Information Science.

She joins 28 early-career scientists from around the world in this year’s cohort, with each receiving support for one to two years, $100,000 in salary support per year, individualized mentoring, and a series of professional development sessions as they pivot to the next stages of their research agendas.
The fellowship is a program of Schmidt Futures, the philanthropic initiative of Eric and Wendy Schmidt that aims to tackle society’s toughest challenges by supporting interdisciplinary researchers at the start of their careers.
“Our latest group of Schmidt Science Fellows embodies our vision for this Program at its inception five years ago,” says Eric Schmidt, co-founder of Schmidt Futures and former CEO and Chairman of Google. “We find the most talented next-generation leaders from around the world and back these impressive young adults with the resources and networks they need to realize their full potential while addressing some of the big scientific questions facing the world. Congratulations to the 2022 Schmidt Science Fellows, I am excited to see where your science takes you and what you will achieve.”
Working at the intersection of materials science, biology, and applied clinical research, Zlotnick’s postdoctoral work will involve developing advanced bioprinting techniques for regenerative medicine. Such advances are necessary to recreate the multi-cellular composition of orthopedic tissues, such as those found in the knee joint. Lab-grown tissue models can then be used to broaden our understanding of how degenerative diseases progress after injury, limit the need for animal models, and serve as a platform for therapeutic discovery.
The U.S. Food and Drug Administration has expanded its approval for Kymriah, a personalized cellular therapy developed at the Abramson Cancer Center, this time for the treatment of adults with relapsed/refractory follicular lymphoma who have received at least two lines of systemic therapy. “Patients with follicular lymphoma who relapse or don’t respond to treatment have a poor prognosis and may face a series of treatment options without a meaningful, lasting response,” said Stephen J. Schuster, the Robert and Margarita Louis-Dreyfus Professor in Chronic Lymphocytic Leukemia and Lymphoma in the Division of Hematology Oncology. It’s the third FDAapproval for the “living drug,” which was the first of its kind to be approved, in 2017, and remains the only CAR T cell therapy approved for both adult and pediatric patients.
“In just over a decade, we have moved from treating the very first patients with CAR T cell therapy and seeing them live healthy lives beyond cancer to having three FDA-approved uses of these living drugs which have helped thousands of patients across the globe,” said Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in Penn’s Perelman School of Medicine and director of the Center for Cellular Immunotherapies in the Abramson Cancer Center and director of the Parker Institute for Cancer Immunotherapy at Penn. “Today’s news is new fuel for our work to define the future of cell therapy and set new standards in harnessing the immune system to treat cancer.”
Research from June, a member of the Penn Bioengineering Graduate Group, led to the initial FDA approval for the CAR T therapy (sold by Novartis as Kymriah) for treating acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.
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.”

A new feature in Chemistry World explores the history of CAR (chimeric antigen receptor)-T cell therapy, a revolutionary type of therapeutic treatment for certain types of cancer. One of the pioneers of CAR-T cell therapy is Carl June, Richard W. Vague Professor in Immunotherapy in the Perelman School of Medicine and member of the Penn Bioengineering Graduate Group. His groundbreaking research opened the door for FDA approval of the CAR T therapy called Kymriah, which treats acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.
After a year of hybrid learning, Penn Bioengineering (BE) seniors were excited to return to the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace for Senior Design (BE 495 & 496), a two-semester course in which students work in teams to conceive, design and pitch their capstone projects in bioengineering.

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 Penn Bioengineering recognizes the outstanding work of two graduate students in Bioengineering: Erin Berlew and Rhea Chitalia.
Erin Berlew, Ph.D. candidate in Bioengineering
Erin Berlew is a Ph.D. candidate in the lab of Brian Chow, Associate Professor in Bioengineering. She successfully defended her thesis, titled “Single-component optogenetic tools for cytoskeletal rearrangements,” in December 2021. In her research, she used the BcLOV4 optogenetic platform discovered/developed in the Chow lab to control RhoGTPase signaling. Erin earned a B.S. in Chemistry from Haverford College in 2015 and was an Americorps member with City Year Philadelphia from 2015-2016. “Erin is a world-class bioengineering with an uncommon record of productivity gained through her complementary expertise in molecular, cellular, and computational biology,” says Chow. “She embodies everything wonderful, both academically and culturally, about our graduate program and its distinguished history.” Erin’s hobbies outside the lab include spending time with family, reading mystery novels, enjoying Philadelphia, and crossword puzzles. In the future, she hopes to continue to teach for the BE department (she has already taught ENGR 105 and served as a TA for undergraduate and graduate courses) and to conduct further research at Penn.
Rhea Chitalia, Ph.D. candidate in Bioengineering
Rhea Chitalia is a Ph.D. candidate in Bioengineering and a member of the Computational Biomarker Imaging Group (CBIG), advised by Despina Kontos, Matthew J. Wilson Associate Professor of Research Radiology II in the Perelman School of Medicine. Rhea completed her B.S.E. in Biomedical Engineering at Duke University in 2015.
