Research Profile

Dr. Subrata Deb,
B.Pharm, M.Pharm, PhD

I am interested in elucidating the potential mechanisms of vitamin D deficiency and metabolic drug interactions with a focus on prostate cancer/breast cancer and liver disorders. My research is focused on the application of absorption, distribution, metabolism, excretion and toxicity (ADMET)-based principles to understand the disposition of vitamin D and therapeutic agents in hormonal cancers and liver disorders. My work on cytochrome P450-related interactions of drugs and natural products with endobiotics and xenobiotics has highlighted the vital role of metabolic interactions in disease pathophysiology and experimental therapeutics. I am currently utilizing in silico tools such as simulation of ADMET and their associated interactions in pharmacokinetic and pharmacodynamic (PK-PD) modeling. Along with the laboratory research models, I also work with the health and nutritional databases to identify potential biomarkers and to provide mechanistic analyses in hepatic dysfunction and its related drug interactions.  I have keen interest in applying pharmacogenomic concepts in unraveling drug interaction and drug action outcomes in patients.
