Sushant Kumar, Ph.D.

Sushant Kumar, Ph.D.
Postdoctoral fellow, Du Laboratory


Dr. Kumar earned his B.S. in agriculture from G.B. Pant University of Agriculture and Technology, India and M.S. in life sciences from Jawaharlal Nehru University, India. From 2011-17, he pursued his Ph.D. in molecular biophysics from Indian Institute of Science (IISc), Bangalore, India. His graduate work focused on studying the structure of DNA damage-inducing protein 1 from protozoans using x-ray crystallography and studying their interactions with inhibitors. Dr. Kumar also worked to understand the strain and pH-dependent structural changes in rotaviral enterotoxin NSP4. He characterized a Zn-bound single-chain camelid antibody raised against a secondary active transporter NorC from Methicillin-resistant Staphylococcus aureus and determined the X-ray structure of the transporter in complex with the camelid antibody. In 2021, he joined Van Andel Institute as a postdoctoral fellow in the lab or Dr. Juan Du.
