Cyril has been employed with CSU since October 2010. He initially served as a Senior Theriogenology Clinician at the Veterinary Clinical Centre, and later accepted his current position of Lecturer in Veterinary Reproduction at CSU.

Cyril graduated with a degree in Veterinary Science (BVSc) from Kerala Agricultural University (India), and subsequently worked as a Veterinarian for the State Government of Kerala (India) for over 10 years. During this time, he was in-charge of various veterinary institutions with clinical, regulatory and administrative duties. In 2006, Cyril moved to Canada and was accepted into a competitive doctoral residency program in Theriogenology (DVSc) at the Ontario Veterinary College (University of Guelph, Canada). Cyril successfully completed his DVSc program in 2010 and was immediately recruited as a Theriogenologist at the Atlantic Veterinary College, University of Prince Edward Island (Canada). After working here for a short while, Cyril moved to Australia and joined CSU where he is currently employed.

In addition to his doctoral degree in veterinary science, Cyril has also successfully completed the American Specialty Board Certification Exam and is a Diplomate of the American College of Theriogenologists. He is also an associate member of the Australian and New Zealand College of Veterinary Scientists. Since 2012, Cyril has been serving as a Category A member (Veterinary Experience) of the CSU Animal Care and Ethics Committee (ACEC).

His main clinical interests include management of reproduction in equine, bovine and companion animals, infertility, obstetrics, embryo transfer, and transcervical insemination in dogs. Research interests include canine, bovine and equine reproduction.
