Scientific Focus

Current Research and Scholarly Interests

My main clinical specialties are radiation treatment of lung cancer and head & neck cancer, and I serve as the Thoracic Radiation Oncology Program Leader.

My clinical research interests include 4-D multimodality imaging of tumor and organ motion using CT, PET, and MR; novel functional/metabolic imaging of tumor hypoxia and lymphatic drainage; and implementation and clinical trials of high-precision image-guided radiation therapy including 4-D IMRT, dynamic conformal arc radiotherapy (DCART) and volumetric modulated arc therapy (VMAT), and stereotactic ablative radiotherapy (SABR). My preclinical and translational research interests include novel functional imaging of inflammation as a mechanism of late normal tissue radiation injury, novel reconstruction and processing methods for 4-D imaging data to reduce artifacts and extract functional/physiologic information, and the radiobiology of tumor hypoxia and SABR.
