Research interests include the study of the molecular mechanisms causing tumor resistance to radiation and chemotherapy. A tumor resistant signaling network regulated by the transcription factor NF?B and a group of proteins that translocate to the mitochondrion are being investigated in an array of human cancers including breast, lung, prostate and liver.
Additional projects are related to radiation-induced adaptive response in normal tissues and in the radiation-resistant cancer stem cells. The goal of these studies is to find therapeutic targets to enhance cancer cure rates by radiotherapy.
