Dr. Gettys has a broad interest in the signaling systems which link cell surface receptors to transcriptional programs regulating the metabolic and endocrine functions of adipose tissue. An additional area of interest includes the nutrient sensing mechanisms linking modulation of specific subsets of genes by dietary macronutrients, including lipids and amino acids.
