My laboratory has worked in the areas of molecular endocrinology, molecular nutrition, gut development, and animal models of disease (reproductive and cancer). Work in the laboratory over the last ten years and continuing through the present has focused on 1) molecular mechanism(s) of action of select dietary factors and obesity in colon and breast cancers 2) molecular physiology of Malic Enzyme 1 (ME1), and 3) characterization of Krüppel-Like Factors (KLFs) in normo- and patho-physiology. Current projects use a combination of in vitro and in vivo approaches, mouse models, and human clinical specimens and are translational and collaborative. While research has been a focus of my (and my mentees) career development, I remain an active contributor to graduate and medical education and mentoring.
