Dr. Z. Dave Sharp's lab explores novel strategies to prevent diseases while mitigating morbidities associated with aging, thereby reducing suffering and looming economic burden. 

They study how chronic mTOR inhibition prevents, delays, and/or reduces the severity of cancer while mitigating other negative effects of aging. 

Their experiments show this is possible with a novel enteric formulation of rapamycin, eRapa. Their current research goals aim to understand the mechanism of action of eRapa in the prevention of colon cancer using mouse models combined with genetic, epigenetic and protein synthesis profiling technologies.
