Being always fascinated by molecules and the ways they shape the biology, Dr Das's research career has focused on understanding how metabolites in our body affect aging and age-associated diseases. After obtaining his PhD from Stanford University, studying enzymes in bacteria that make bioactive polyketides, Dr Das did his postdoctoral work at Harvard University, Massachusetts Institute of Technology and University of New South Wales (UNSW) under the tutelage of Prof. Leonard Guarente and Prof. David Sinclair, where he identified the role of NAD+ metabolism and H2S signaling in reversing vascular and muscle aging. He has made significant discoveries in the field and published his research in top journals including Cell, Nature Communications, Aging Cell and Redox Biology. His scientific contribution has been highlighted by eminent scientists in the field, led to many invited talks in national and international conferences, has garnered the attention of national and international media and led to many successful grants and industry collaborations. Currently, he is an Adjunct Lecturer at UNSW Sydney and an Associate Director (Research) at Tranquis Therapeutics, where he leads a team of researchers in understanding the role of immunometabolism in age-related diseases and overseeing the drug development program.
