Ph.D., University of Oklahoma Health Sciences Center

Description of Research Interests

Research interests relate to the regulation of lipid metabolism and the relationship of metabolism to food intake with relevance to both human and animal nutrition. Current areas of research relate to:

  1. Examination of alternative feed ingredients for use in swine or poultry diets
  2. Effect of dietary fat on growth performance and carcass composition
  3. Use of feed enzymes to improve nutrient availability

Courses Taught

ADSC 3300-Animal Nutrition and Metabolism
ANNU 6370-Monogastric Nutrition
ANNU 8350-Carbohydrates and Lipids in Animal Nutrition
