My laboratory based research focuses on developing strategies of improving the radiation response, using agents that modify the tumor microenvironment and alter cellular signaling. In particular we have focused on the PI3K/mTOR pathway, which is upregulated in many human cancers. Our research suggest that inhibition of this pathway can increase the intrinsic sensitivity of tumor cells to radiation and also decrease tumor oxygenation.
