For the past 25 years, I have focused on the development of curative treatment of gastrointestinal malignancies with radiation therapy. The limitation to curative treatment of luminal gastrointestinal tumors such as rectal cancers is the tolerance dose to the gastrointestinal mucosa, which limits the doses to a palliative or adjuvant dose. I have also lead innovative dose escalation to ablative doses in liver and pancreas tumors.  Overall, I have received 4 major teaching awards, and Director, and the other currently serves as Professor and Chairman of Gastrointestinal Radiation Oncology  for16 years and Program Director of the residency program at MD Anderson for 10 years. I served as the Chairman of the Gastrointestinal Committee of the Radiation Therapy Oncology Group and more recently as the Chair of the Non-colorectal GI committee of NRG Oncology for 10 years, which makes me uniquely qualified to understand how to translate technology discovery to the community. My H-index is 90.
