Description of Research Expertise

RESEARCH INTERESTS:
1. Defining Mechanisms and Reducing Toxicity from Normal Tissue Damage Caused by Ionizing Radiation: These projects center on modeling the physical patterns of dose deposition by x-rays, gamma rays and charged particles and determining the mechanism(s) that lead to normal tissue toxicity. From a greater understanding of these mechanisms, these projects seek to identify and formulate potential radiation protectors and mitigators for use in human medicine.

2. Cellular Signaling and PDT cytotoxicity: This project is focused on defining the molecular mechanism by which PDT-initiated growth factor and anti-oxidant signaling leads to decreased PDT-mediated cytotoxicity in human cancer cells and tumors.

3. Clinical trials of RT and PDT: These projects involve using insights gained from pre-clinical studies to design early phase interventional trials for patients with cancers that are difficult to treat using current standard modalities.
