  • Biography

    I joined the Department of Animal and Veterinary Science at the University of Idaho in 2008, after twelve years on the faculty at Michigan State University.

    My teaching responsibilities include instruction for the Science of Animals that Serve Humanity (AVS 109), Science of Animal Husbandry (AVS 209), Live Animal and Carcass Evaluation (AVS 263), and Animal Products for Human Consumption (AVS 363). The laboratories associated with AVS 209, AVS 263, and AVS 363 provide “hands-on” experience for students in livestock husbandry practices, livestock selection, market animal and carcass evaluation and pricing, and meat processing, respectively. Ron Richard (UI Meat Lab Manager) and I team teach the AVS 263 and AVS 363 courses, and students benefit from our combined expertise. A Growth and Lactation course (AVS 463) will be offered beginning the fall of 2011, and I intend to teach the growth portion of that course as well. I provide annual guest-lectures on meats-related topics in Beef Cattle Science (AVS 474) and Introductory Animal Science (WSU, AS 101). My goal is to enthusiastically provide the best information available in a manner that will stimulate thought, inquiry, and application of knowledge.

  • Research Projects
     My research program is focused on improving beef quality. This includes both cellular research to understand the fundamental regulation of fat accumulation in subcutaneous and intramuscular adipose tissue depots, as well as applied research to measure and improve beef palatability.
    Both graduate and undergraduate students play an active role in conducting research in my laboratory. Thus, the research provides a training opportunity, as well as valuable information for industry. Our current projects examine the effects of long-chain fatty acids on the differentiation of preadipocytes from different anatomical fat depots, and explore marination strategies to improve tenderness of the beef bottom round.

  • Outreach Projects
     AVS Teaching Committee;  the Sheep Unit Advisory Committee; and I participate in a variety of activities for youth (e.g. Ag Days workshops and judging contest, FFA CDE’s) and industry (e.g. Beef 300, Lamb 300)
