This animal science expert witness has over 30 years of experience in animal nutrition, with a research-focused background in ruminant physiology, digestion, and metabolic function. Their work centers on evaluating the relationships between diet digestion, gut metabolism, and nutrient absorption across multiple animal classes, including beef and dairy cattle, sheep, goats, and companion animals. This foundation supports analysis in legal matters involving feeding practices, nutritional adequacy, and the physiological impact of dietary components on animal health.

Their research-driven practice includes the use of model systems to study digestion kinetics, nutrient flux, and metabolic responses to dietary inputs. Key areas of analysis involve carbohydrate and protein digestion, mineral metabolism, ruminal fermentation, and nitrogen balance, as well as the effects of dietary supplements and feed composition on large animal performance. Additional experience extends to companion animal nutrition, including digestive physiology and nutrient utilization. These areas are relevant in disputes involving feed formulation, dietary deficiencies, livestock performance, and alleged nutrition-related health outcomes.

The expert holds a Ph.D. in animal science with specialization in ruminant nutrition, supported by graduate and undergraduate study in animal nutrition. Their academic work includes extensive teaching of graduate-level courses in animal nutrition, metabolism, and research techniques, along with supervision of more than 30 advanced degree programs and postdoctoral research efforts. Research contributions include authorship of over 170 peer-reviewed scientific journal articles addressing topics such as starch digestion, gastrointestinal metabolism, and nutrient utilization in ruminants, providing a technical foundation for evaluating scientific evidence in animal nutrition matters.

Professional involvement includes participation in American Society of Animal Science and related scientific organizations, along with contributions to peer-reviewed journal activities in areas related to ruminant digestion and metabolism. Additional responsibilities have included involvement in institutional animal care and use oversight activities, reflecting familiarity with regulatory and compliance considerations in animal research environments.
