Summary
Sayak attended medical school in Calcutta, India, and soon after joined PhD program in Biology at the University of Rochester, where his doctoral thesis focused on the role of bile acids in the molecular pathogenesis of GERD and Barrett’s Esophagus. He continued his research interests in gastrointestinal carcinogenesis, tissue engineering and gastrointestinal motility through his next few post-doctoral positions at the University of Rochester and the Mayo Clinic, Rochester. Currently, he is pursuing Anatomic Pathology residency program at the UMN. Through clinical training and research support at the program, he hopes to advance his career as a physician researcher dedicated to understanding the molecular dynamics of carcinogenesis. Sayak is also an amateur musician, and loves to spend time with his wife playing VR games, cooking, camping and travelling.
