HEC Approved Supervisor
Prof. Dr. Nasim Ahmad graduated in Veterinary Medicine (DVM) in 1981 and received his Master’s degree (MSc Hons) in Animal Reproduction in 1984, from the College of Veterinary Sciences, Lahore and in 1996 PhD in Reproductive Physiology from West Virginia University, USA. Dr. Ahmad is presently Professor (TTS) of Theriogenolgy and Dean Faculty of Life Sciences and Business Management. He earlier served as Dean, Faculty of Veterinary Science, Chairman of Department, Director Research, Director External Linkages at the University of Veterinary and Animal Sciences, Lahore. His research interests are improving fertility through enhancing post-thaw semen quality and optimizing protocols of estrus synchronization and ovulation. Earlier, he directed male infertility laboratory (for human) in New York. He is credited in introducing the use of ultrasonography in Animal Reproduction research, training and extension in Pakistan. Prof. Dr. Ahmad is author of more than sixty publications in high impact factor journals. He is a regular reviewer for Theriogenology and Animal Reproduction Science. He has won competitive research grants as PI worth more than Rs. 28 million and development projects of more than Rs. 52 million. He has supervised or co-supervised fifty six Master’s and two Doctoral students. He is the current President of Society for Animal Reproduction of Pakistan. He remained Honorary Secretary of Society of Prevention of Cruelty of Animals, Punjab. In recognition of his research work and he has been awarded “PARC Scientist of the year: 1999”, Research Productivity Allowance three times from PCST, ‘Best University Teacher’ Award for the year 2007 from HEC and Sitare-e-Imtiaz 2008, Presidential Civil Award.
