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.
