Research

I conduct aging research in Dr. John Kopchick鈥檚 laboratory to understand the role of growth hormone action in aging and age-related diseases. Specifically, I work with mouse lines that have a postnatal disruption of the growth hormone receptor and study the molecular, metabolic, and lifespan alterations in these mice.
