Focus Groups: 
Signal Transduction
PhD, Biochemistry & Biophysics, University of North Carolina-Chapel Hill
Postdoctoral,Pharmacology & Cancer Biology, Duke University
Research Summary: 
Guanine Nucleotide Binding Proteins, pancreatic beta-cell biology, insulin secretion, diabetes pathophysiology
Research Detail: 

Dr. Kimple leads a multi-level research team whose focus is on understanding how the beta-cells of the pancreas respond to nutrient and hormonal stimulation to affect biological changes. Her group is especially interested in elucidating how dysfunctional G protein-coupled receptor signaling pathways contribute to the pathogenesis of type 1 and type 2 diabetes and in translating these insights into new and improved diabetes therapeutics. Dr. Kimple's research has been funded almost continuously from her PhD onwards by the National Institutes of Health and the Juvenile Diabetes Research Foundation, among other agencies. Her work has been featured in several university press releases and patent applications. Dr. Kimple has been the recipient of several awards, including a Preparing Future Faculty Fellowship from Duke University, where she learned the skills necessary to be a successful mentor and teacher while maintaining a top-tier research laboratory.
