Welcome to the Department of Biochemistry and Biophysics

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

Sergei Vinogradov, PhD

Sergei Vinogradov's research is focused on the development of optical probes for biological microscopy and imaging. The laboratory has long-standing interest in metalloporphyrins, which can be used as sensors for oxygen, pH, metal ions and other environmental parameters of biological systems. Two-photon phosphorescence lifetime microscopy (2PLM) of oxygen, developed by the lab, is now broadly used in neuroscience and stem cell biology. Recently, the group theoretically predicted a new class of porphyrins with exceptionally high two-photon absorption cross-sections, and using them developed probes for 2PLM with 100 times higher performance. The current focus is on exploration of higher order optical non-linearity, such as in three-photon absorption, to gain deeper insight at the energy metabolism in the brain.
