He was promoted to Associate Professor in 1986 and Professor in 1992. His current responsibilities include teaching one undergraduate course, entitled “Dairy-Poultry Science” and one graduate course, entitled “Ovarian Physiology,” and serving as faculty coordinator for the Kansas Artificial Breeding Service Unit (KABSU).
