Biography

I received my Ph.D. from Department of Zoology (Biochemistry and Molecular biology Lab), BHU, Varanasi in 2004 where I explored the mechanisms of differential gene regulation by Androgen Receptor promoter during aging in the mouse brain cortex under Prof. M.K. Thakur. Having gained experience in Molecular Neurobiology, I joined as a postdoc under Prof. V. Ravindranath at NBRC, Manesar where I studied the role of Estrogens as neuroprotectors for Parkinson’s and Alzheimer’s disease.

Thereafter, I joined as a postdoc under Prof. Pierre Chambon/Prof. Daniel Metzger at IGBMC, Strasbourg, France to work on the role of nuclear receptors in Prostate Cancer and to develop and validate mouse models that mimic the kinetics of human prostate cancer progression. Subsequently, I moved to A*STAR IMCB, as a research fellow to investigate the role of Cdks in Meiosis and epigenetic modifiers in Head and Neck and Gastric cancer and had profiled patient tumors for pre-clinical testing of chemotherapeutic agents using PDX. Thereafter I joined as an Associate Professor at YRC in 2018 to continue working on Epigenetics and Cancer Biology.
