Dr. Chowdhury earned his bachelor’s degree in Zoology with Molecular Biology as allied subject from Calcutta University, India, in 1999. In 2001, he completed his master’s degree from Calcutta University in Zoology with specialization in Endocrinology. Then in 2003, he qualified the National Eligibility Test (CSIR, Govt. of India) to be eligible for government scholarship to pursue his doctoral research. He received his Ph.D. in 2009, under the guidance of Dr. Keya Chaudhuri, from the Molecular & Human Genetics Department, Indian Institute of Chemical Biology, Kolkata, with significant contributions in the field of Molecular Biology and Toxicology. He joined Dr. Wogan's research group as a postdoctoral associate in June, 2009.

Research Interests

In his Ph.D. research, Dr. Chowdhury formulated an effective protective regimen to arsenic toxicity; the research findings were of considerable public health impact considering the millions exposed in India & Bangladesh to groundwater arsenic contamination. The antidote attenuated arsenic toxicity by chelating it from biological systems. The spectrum of his research also included demonstration of carcinogenic potential of arsenic by analysis of gene expression profiles in arsenic-exposed human subjects by microarray analysis; a novel bio-marker for arsenic toxicity was identified. He also made significant contributions in understanding the paradoxical role of arsenic in cancer therapeutics. Following his expertise in toxicology and cancer molecular biology, Dr. Chowdhury presently is working on analyzing the pleiotropic effects of nitric oxide (NO) in diverse cellular tumor micro-environments. He is in the process of characterization of NO-induced molecular events and post-translational protein modifications that can lead tumor cells to become refractory to chemotherapy facilitating cancer progression.
