Research Program Overview

My program of research in nutritional physiology has focused on the molecular and biochemical characterization of functional units of nutrient transporters and enzymes, which together achieve a biochemical capacity. Because of their importance in nutrient assimilation and use, my research program has emphasized the study of tissue-, age-, diet- (including form of supplemental selenium), metabolic acidosis, ergot alkaloid-dependent expression and activity of proteins in ruminants. Based on findings from these commercially-relevant experimental models, my most recent research approaches include characterization of multiple gene and protein expression profiles, in addition to understanding how the mechanisms by which the expression and function of specific proteins is regulated. However, my broad research stratagem is not to study/characterize complete transcriptomes or proteomes but rather to understand how constitutive and inducible aspects of biochemical pathways are regulated, in response to physiological challenges of importance to production agriculture.
