Prof. Dr. Ijaz Ahmad has served as Acting Vice Chancellor at NUR International University and currently he is Pro Vice Chancellor, Academics and Research.

He was a member of the Central Licensing and Registration Boards, Ministry of Health, Islamabad for five years. He also served as a member of the Expert Committee on Biological Drugs, Ministry of National Regulations and Services, Drug Regulatory Agency of Pakistan for three years.

He was given the “Best Teacher Award’ in 2006 by the Higher Education Commission(HEC), Islamabad. He was the first faculty member in all of the Veterinary and Agricultural Institutes of Pakistan to fulfill the ‘Model Tenure Track Process Statutes’ eligibility criteria for the selection of Trnure Track Professor since 2000 outlined by the HEC and the first HEC approved PhD supervisor (2004). He has supervised twelve MSc (Hons) / MPhil and four PhD students and was a member of the advisory committee for 7 PhD and 12 MPhil students.

He has authored / co-authored more than 62 publications in international refereed impact factor Journals and presented more than 50 papers in international conferences. His Current impact Factor is 85 and his research papers are frequently cited in International Refereed Journals and Textbooks. He received a Research Award from the Society for Theriogenology, Orlando, FL, USA in 1988.

In 2000, he was listed as a Productive Scientist of Pakistan in ‘Scientific Research in Pakistan’ published by Pakistan Council for Science and Technology and was awarded the Research Productivity Award. He has been awarded this Research Productivity Award seven times since then.

His research interests lie in the areas of sperm motility, electroporation to transfect foreign DNA into sperm and ovum; in vitro sperm capacitation; oocyte maturation, and zona-free hamster oocyte penetration assays; in vitro fertilization and micromanipulations of zygote; cryopreservation of sperm and embryos, and granulosa cell, uterine and oviduct epithelial cell cultures. He won and used purposefully seven international and three national research and development grants.
