Rate My Professor Sean Limesand

Dr. Limesand’s research program employs ovine models to study early-life programming of metabolic diseases, particularly intrauterine growth restriction (IUGR), placental insufficiency, and disruptions in fetal pancreatic β-cell development and insulin secretion. His investigations span molecular to whole-animal levels, exploring adrenergic signaling, catecholamine effects, and insulin action in skeletal muscle. Funded continuously by the NIH for 19 years, along with support from the Bill & Melinda Gates Foundation, USDA, and JDRF, his impactful work is evidenced by over 5,400 citations and publications including “Placental insufficiency decreases pancreatic vascularity and disrupts hepatocyte growth factor signaling in the pancreatic islet endothelial cell in fetal sheep” (Rozance et al., Diabetes, 2015), “Reductions in insulin concentrations and β-cell mass precede growth restriction in sheep fetuses with placental insufficiency” (Limesand et al., Am J Physiol Endocrinol Metab, 2013), and “Chronic fetal hypoglycemia inhibits the later steps of stimulus-secretion coupling in pancreatic β-cells” (Limesand et al., Am J Physiol Endocrinol Metab, 2007). He has earned the Research Faculty of the Year award, serves on editorial boards for the Journal of Endocrinology and Journal of Molecular Endocrinology, leads in the Perinatal Research Society, and has given invited lectures at institutions worldwide.
