Rajadurai Rajamahendran

(in memoriam) PhD, Professor Emeritus, Applied Animal Biology

rajadurai.rajamahendran@ubc.ca

Education

McGill University, 1976, PhD

McGill University, MSc

Ceylon, BVSc

Research

The current research interests of Dr. Rajamahendran’s group are to:

  1. investigate GnRH-R and GnRH systems in ovaries, reproductive tracts, gametes and early embryos in the bovine using molecular techniques and understand it’s role in ovarian / oviduct / uterine function, sperm function, fertilization, and early embryo development,
  2. study the reasons for reduced fertility in postpartum dairy cows by comparing in vivo and in vitro progesterone synthesis, genes associated with corpus luteum function, embryo quality, and uterine environment, of dairy heifers and lactating cows,
  3. develop reproductive technologies to advance postpartum ovarian activity, for timed artificial insemination, and to reduce early embryonic mortality in dairy cattle, and
  4. develop in-vitro tests to predict fertility of dairy bulls in the field. Research funded by Natural Sciences and Engineering Research Council of Canada, Agriculture and Agri-Food Canada, British Columbia Investment Agriculture Foundation, and Westgen Endowment Fund.
