Dr. Sujay Chattopadhyay holds an M.Tech. in biotechnology from Indian Institute of Technology, Kharagpur, and Ph.D. in computational biology from Indian Association for the Cultivation of Science, Kolkata.
His research focuses on understanding diverse evolutionary mechanisms in microbes, with an emphasis on the evolution of microbial virulence. Along with his continuing research on E. coli and Salmonella, he is currently engaged in deciphering genome-wide adaptive footprints in Treponema pallidum, Bartonella bacilliformis and Helicobacter pylori. His another work, primarily in E. coli, involves genome-wide detection of high-resolution markers discriminating sub-ST (sequence type) clones, and analysis of association of those clonotypes with antimicrobial resistance and clinical manifestation.
