Welcome to the Department of Biochemistry and Biophysics

Kristen W. Lynch, PhD
Ronen Marmorstein, PhD
Vice Chair

As one of the first departments of Biochemistry and Biophysics in the nation, we are proud of our strong tradition of combining cutting-edge technology with impactful biology. We continue to leverage this interdisciplinary approach to yield break-through discoveries in biomedicine.

Our faculty of over 30 primary and secondary members cover a broad range of research areas, with particular strengths in structural biology, chemical biology, gene regulation and protein folding. 

We are also the proud home of the Eldridge Reeves Johnson Research Foundation which offers advanced physical instrumentation and instruction to researchers across campus.

We are actively growing, with several recent hires, and our faculty are broadly engaged across campus with many joint appointments in other departments, institutes and centers.

We welcome you to learn more about our department in the following pages or contact us.

Faculty Spotlight

Rahul Kohli, MD, PhD

Rahul Kohli is a physician-scientist with appointments in both the Department of Medicine and the Department of Biochemistry and Biophysics. The Kohli lab is focused on the study of enzymes that modify and mutate DNA, given the central role that genome dynamics play in epigenetics and in host-pathogen interactions. These processes are open to interrogation by enzymology and chemical biology approaches. The lab also aims to harness the biotechnological or therapeutic potential of DNA altering enzymes and pathways, with applications that include new sequencing methodologies, targeted genome editing, and combating the evolution of antibiotic resistance. Dr. Kohli is passionate about supporting pathways that meld fundamental science and medicine, and in this spirit, also serves as an Associate Program Director for Penn’s MD/PhD program.
