Kevin Johnson: Informatics Evangelist

by Ebonee Johnson

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.”

Researchers Develop Technology to Keep Track of Living Cells and Tissues

SAFE Bioorthogonal Cycling

Cells in complex organisms undergo frequent changes, and researchers have struggled to monitor these changes and create a comprehensive profile for living cells and tissues. Historically researchers have been limited to only 3-5 markers due to spectral overlaps in fluorescence microscopy, an essential tool required for imaging cells. With only this small handful of markers, it is difficult to monitor protein expressions of live cells and a comprehensive profile of cellular dynamics cannot be created. However, a new study in Nature Biotechnology addresses these limitations by demonstrating a new method for comprehensive profiling of living cells.

Jina Ko, PhD

Jina Ko, Assistant Professor in Bioengineering in the School of Engineering and Applied Science and in Pathology and Laboratory Medicine in the Perelman School of Medicine, conducted postdoctoral research at Massachusetts General Hospital (MGH) and the Wyss Institute at Harvard University, and the work for this study was done under the supervision of Jonathan Carlson M.D., Ph.D. and Ralph Weissleder M.D., Ph.D. of MGH. Ko’s lab at Penn develops novel technologies using bioengineering, molecular biology, and chemistry to address diagnostic challenges for precision medicine.

To address these limitations in microscopy, the team developed a new chemistry tool which was highly gentle to cells. This “scission-accelerated fluorophore exchange (or SAFE)” method utilizes “click” chemistry, a type of chemistry that follows examples found in nature to create fast and simple reactions. This new SAFE method functions with non-toxic conditions to living cells and tissues, whereas previous methods have used harsh chemicals that would strip off fluorophores and consequently would not work with living cells and tissues.

With the development of SAFE, the authors demonstrated that researchers can now effectively perform multiple cycles of cell profiling and can monitor cellular changes over the course of their observations. Instead of the previous limitation of 3-5 markers total, SAFE allows for many more cycles and can keep track of almost as many markers as the researcher wants. One can now stain cells and quench/release fluorophores and repeat the cycle multiple times for multiplexing on living cells. Each cycle can profile 3 markers, and so someone interested in profiling 15 markers could easily perform 5 cycles to achieve this much more comprehensive cell profile. With this breakthrough in more detailed imaging of cells, SAFE demonstrates broad applicability for allowing researchers to better investigate the physiologic dynamics in living systems.

Read the paper, “Spatiotemporal multiplexed immunofluorescence imaging of living cells and tissues with bioorthogonal cycling of fluorescent probes,” in Nature Biotechnology.

This study was supported by the Schmidt Science Fellows in Partnership with the Rhodes Trust and National Institutes of Health, National Cancer Institute (K99CA256353).

Bioengineering Graduate Student Hannah Zlotnick Named Schmidt Science Fellow

by Evan Lerner

Hannah Zlotnick

Hannah Zlotnick, a graduate student in the Department of Bioengineering and a member of the McKay Orthopaedic Research Laboratory in Penn’s Perelman School of Medicine, has been named a Schmidt Science Fellow.

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.
