    Qualification:

    Degree Name of the College/Institute and University Passing Year
    B.Sc.(Life Sciences) Himachal Pradesh University, Shimla, H.P. 1996
    M.Sc. (Biotechnology) Punjabi University, Patiala, India 1998
    Ph. D. (Biotechnology) Cochin University of Science & Technology, Kochi, India. 2009

    Research:

    My research interests are in functional genomics related to buffalo oocytes and early embryos, circulatory miRNAs associated with pregnancy. I am also focus on molecular determinants of bull fertility, coding and non-coding carriage of extracellular vesicles and their carriages in seminal plasma in relation to bull fertility and heterologous expression of buffalo sperm coat proteins.
