Researcher biography
Dr. Mohanathas Gobikrushanth (Gobi) is a lecturer in Production Animal Medicine, with a particular interest in Production Animal Reproduction, within the School of Veterinary Science. Gobi obtained his Bachelor of Veterinary Science (Hons) degree from the University of Peradeniya, Sri Lanka in 2011. Following graduation, he worked as a Companion Animal Clinician in the university's Department of Veterinary Clinical Sciences for a year.
In 2012, Gobi moved to the USA to pursue a veterinary externship program (Research Scholar) at the College of Veterinary Medicine, University of Florida. In 2018, Gobi earned his PhD in Animal Science (Reproduction) from the University of Alberta, Canada. His doctoral research was focused on identification and evaluation of novel reproductive phenotypes for genomic selection to enhance fertility of dairy cattle through multiple-locational studies conducted in Canada and Ireland. Following his PhD, Gobi undertook a one-year postdoctoral fellowship with an array of studies involving both dairy and beef cattle reproduction at the University of Alberta, Canada.
In 2022, Gobi completed his 3-year combined clinical MS (Project-based; uterine microbiome of dairy cows) and residency in Production Animal Theriogenology at the Western College of Veterinary Medicine, University of Saskatchewan, Canada before joining the School of Veterinary Science, UQ.
Gobi's research focuses on strategies to enhance reproductive efficiency in production animals with a special interest in the bovine species.
