Dr. Sathya Velmurugan obtained her B. V. Sc. from Madras Veterinary College, TANUVAS, Chennai. For M. V. Sc., she specialized in Animal Reproduction, Gynaecology and Obstetrics at the College of Veterinary Science, Punjab Agricultural University (now GADVASU), Ludhiana. She obtained her Ph. D. in Biomedical Sciences (Neuroendocrinology) from the University of Edinburgh, UK, where she studied actions of appetite peptides (leptin, secretin and NPY) on hypothalamic oxytocin and vasopressin neurons in rats using in vivo electrophysiology. She did her postdoctoral research at Rush University Medical Center, Chicago (2009-11) and Rosalind Franklin University of Medicine and Science, North Chicago (2011-13) in the field of Physiology. She joined the National Institute of Animal Biotechnology in August 2013.

Research Interests:

Infertility disorders, such as repeat breeding and anoestrus, remain as a major problem in cattle and buffaloes even in organized farms. These disorders warrant understanding reproductive physiology at the molecular, cellular and systemic level so as to design novel therapeutic strategies. She is interested in the regulation of reproductive axis and ovarian activity by the newly discovered hypothalamic neuropeptide, kisspeptin. Kisspeptin research in cattle and buffaloes has immense potential in treatment strategies for advancing puberty, oestrus induction in anoestrous animals and improving conception in repeat breeders. Male fertility constitutes half of the success rate in conception. Hence, it is imperative to ensure that the semen quality is at its best in an artificial insemination regimen. The ultimate test for semen quality is fertility itself. However, in vitro semen function tests are also handy in estimating the quality, especially when robust tests are used with advanced technologies such as confocal microscopy and flow cytometry. In addition, mitochondrial bioenergetics and respiratory chain activities also determine the quality of spermatozoa. She is interested in studying these functions and correlating them with fertility. To delve into basic research, she would like to establish an electrophysiology lab to study the hypothalamic neurons involved in reproduction in vivo as well as in brain slices.
