John Parrish grew up in Fresno California and obtained a BS in Animal Science from California State University Fresno in 1997 (summa cum laude), a Ph.D. in Animal Science and Physiology from Cornell University in 1984 and was a postdoctoral scientist in the Department of Meat and Animal Science at UW-Madison from 1983 – 1988. In 1988 he was hired as an Assistant professor, promoted to Associate Professor in 1995, and Professor in 2000. The department has undergone name changes from Meat and Animal Science, Animal Sciences and now Animal Sciences and Dairy Science.
In his research role, Dr. Parrish’s focus has been on male physiology. In that role, he has worked on bovine sperm capacitation, in vitro fertilization, intracellular regulation of sperm biochemistry, male fertility, imaging approaches to evaluate sperm, the impact of heat stress on bovine and porcine spermatogenesis, and role of human inflammatory bowel disease and treatment on human sperm fertility. Among Dr. Parrish’s major accomplishments are 2 papers that are among the most ever cited in reproductive biology dealing with capacitation of bovine sperm and in vitro fertilization in the bovine having 1611 and 1328 citations respectively.
In his teaching role, Dr. Parrish has been instrumental in reinitializing the use of large domestic animals in the Animal Science teaching program, integration of web-based design into a blended class delivery, websites that allow access to teaching material on general reproduction and equine reproduction used by thousands of individuals each year around the world. On-campus and national level, he has provided leadership in teaching improvement, teaching as a scholarly activity, and integration of technology in teaching.
Dr. Parrish has a wealth of experience in different animal species from the domestic livestock species of cattle (dairy and beef), water buffalo, pigs, horses, llama, camel, chickens, turkeys, the rodents and laboratory species of mouse, rat, hamster, guinea pig, rabbit, the pet species of dog and cat, the fish rainbow trout and flathead minnow, and also in the human.
