Research Area(s)

  • Reproductive biology

Academic Credentials

  • DVM, University of Saskatchewan
  • MS, University of Wisconsin
  • PhD, University of Wisconsin
  • Diplomate ACT, American College of Theriogenologists

Dr. Adams teaches veterinary anatomy in the veterinary curriculum and participates in team-taught graduate courses on:

  • Advanced Physiology and Endocrinology of Reproduction in Mammals
  • Advanced Bovine Reproduction
  • Bovine Reproductive Ultrasonography and Embryo Transfer
  • Research Techniques in Endocrinology and Reproduction

He is a team member of the course Biomedical Rounds that was awarded the Provost's Prize for Innovative Practice of Teaching and Learning, University of Saskatchewan (2008). Dr. Adams also consults on theriogenology cases admitted to the WCVM Veterinary Medical Centre.

Other Appointments

  • President, International Embryo Transfer Society (2014)
  • Chair, International Congress on Animal Reproduction (2012)
  • Chair, Reproductive Science and Medicine Group, University of Saskatchewan
  • Chair, Grant Selection Committee, Natural Sciences and Engineering Research Council (NSERC)
  • Executive, Biomedical Imaging and Therapy Beam Team, Canadian Light Source
  • Associate, Obstetrics and Gynecology, Royal University Hospital, University of Saskatchewan

Research Interests

Dr. Adams has broad interests in basic and applied aspects of reproductive science and medicine, and he is recognized internationally for his work on ovarian function.

He has published classic studies of ovarian follicle development, ovulation and fertility in several species including cattle, camelids, cervids and humans. Results of studies on ovarian function in women by Dr. Adams and co-workers at the University of Saskatchewan was cited as one of the top 100 scientific discoveries of the year by Discover Magazine.

Technical applications resulting from his work include:

  • ovarian synchronization and superstimulation
  • oocyte collection
  • in vitro embryo production and transfer in cattle and camelids
  • 2- and 3-dimensional ultrasonography
  • computer-assisted image analysis

Dr. Adams' current research focuses on 1) ovulation-inducing factor in seminal plasma, 2) the establishment of a germplasm biobank for Canada’s threatened Wood Bison, 3) novel aromatase inhibitor-based method of ovarian synchronization in animals, and 4) embryonic diapause in pinnipeds.

His discoveries on "The nerve of ovulation-inducing factor" and “World's first in-vitro bison calves born at University of Saskatchewan” have been publicized widely in the popular press.
