Dr Muhammad Khalid was trained as a veterinarian from the College of Veterinary Sciences, Lahore and had MSc (Hons) in Animal Reproduction before he obtained his PhD from the University of Nottingham. For his PhD he worked on the control of gonadotrophins release under the supervision of Professor William Haresign. His interest in neuroendocrinology caused him to move to the University of Illinois, Urbana-Champaign, USA to work with Professor Gary Jackson on Control of GnRH release using Push-pull perfusion technique. This was followed by teaching as Assistant Professor in the College of Veterinary Sciences, Lahore for 3 years. Subsequently he joined University of Nottingham as Research Fellow to work on defective luteal function in ruminants before moving to the Royal Veterinary College (RVC) in 1999. He was a senior lecturer in animal reproduction. After twenty years at the RVC, Khalid was retired in November 2019. At the RVC, his research has expanded to include urinary incontinence in the dog along with different aspects of ruminant reproduction. Muhammad was a member of the SRF and a long-term supporter of the Society for many years. He was a Diplomat of European College of Animal Reproduction (ECAR), and a member of the editorial boards of “The International Journal of Veterinary Surgery and Medicine and “Pakistan Veterinary Journal.” We extend our sympathies to his family and his colleagues at this sad time.
