Dr. Gradil, LMV, was drawn to the field of veterinary medicine from an early age, having grown up in Africa as the son of a large animal veterinarian involved with the preservation of wildlife—namely large mammals such as elephants and rhinos. He is the reproductive consultant, or theriogenologist, for the Cummings School of Veterinary Medicine's Hospital for Large Animals. He also teaches equine reproduction in the fall for juniors as well as large animal rotations in reproduction.
In addition to being part of the faculty at the Cummings School, Dr.Gradil is also an associate professor at the University of Massachusetts Department of Veterinary and Animal Sciences. When asked what drew him to Tufts, he says,
Easy answer—the greatest group of people that I have worked with.
Dr. Gradil's areas of clinical expertise and interests are comparative reproduction in large and small animals and wildlife. His area of research expertise include determination of PLC zeta concentration in the sperm of dogs and horses and how it relates to fertility. He finds satisfaction in his fieldwork because it creates the opportunity to produce desirable offspring, relieve infertility and resolve difficult parturition. In terms of his biggest accomplishment at Cummings,Dr. Gradil says he is proudest of building a reputable referral service in reproduction for clients and colleagues in New England.
Dr. Gradil's honors include awards from US-AID, NATO, and the Veterinary Honor Society. He has also been a Fulbright fellow and a Rockefeller Fellow.
In his spare time, he enjoys hiking, pleasure riding, biking and kayaking. He currently resides in Amherst, Massachusetts.
