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.
