My expertise is in clinical Geriatrics and the use of the nematode, Caenorhabditis elegans in aging research. I am particularly interested in the roles of metabolism in the aging process. Specific projects in the lab include: (1) examining how metabolic stress alters proteasomal function and expression, (2) exploring how mitochondrial function changes during aging via non-invasive techniques, (3) determining how amino acids can impair insulin-like signaling, and (4) testing whether oxidative stress responses are controlled by both cell autonomous and non-autonomous mechanisms.
