I received my Ph.D. from Banaras Hindu University, where I explored the mechanisms of differential gene regulation by Androgen Receptor promoter during aging in the mouse brain cortex. Having gained experience in molecular neurobiology, I joined as a postdoc at NBRC, Manesar, for understanding the role of Estrogens as neuroprotectors of Parkinson’s and Alzheimer’s disease. After that, I joined as a postdoc in Prof. Pierre Chambon lab to work on the role of nuclear receptors in Prostate Cancer 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 and epigenetic modifiers in Head and Neck and Gastric cancer and profiled patient tumors for pre-clinical testing of chemotherapeutic responses using PDX. After that, I joined as an Associate Professor at YRC in 2018 to continue working on Epigenetics and Cancer Biology.

Research Interest/Area

Molecular Cell Biology, Cancer Biology, Epigenetics


One of the major hallmarks of Cancer is the aberrant epigenetic modifications in chromatin machinery by which the cells attain a limitless atypical replicative state potentiating cellular proliferation and tumorigenesis that metastasize to distant organs if unchecked. Cancer remains a major burden and public health problem despite the molecular understanding of the disease. The advent of new Omic technologies for profiling different tumors has led to the identification of molecular subtypes of cancers that guide robust early diagnosis and appropriate therapeutic interventions.

Main Objectives:

  • Elucidating epigenetic mechanisms driving cell cycle in different cancer types
  • Identify and validate biomarkers for early detection and diagnosis of cancer and its recurrence
  • Epigenetic role of Cdks in meiosis
  • Tissue regenerative role of Cdks
