Sunil Krishnan, MD, FACP

Present Title & Affiliation

Primary Appointment

Professor, Department of Radiation Oncology, Division of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX

Bio Statement

As an Associate Professor on the gastrointestinal cancer service of the Department of Radiation Oncology, Dr. Krishnan is actively involved in patient care and clinical trials. Also, as the Director of Translational Research for this service, he has basic and translational science laboratory interests. His clinical effort is directed towards developing novel therapies for patients with gastrointestinal tumors. He is the principal investigator of several clinical trials focusing on radiation sensitization strategies for these tumors, especially liver, pancreatic and rectal cancers. His laboratory research interests include: 1) understanding the role of dietary botanicals as radiation modifying agents in rectal and pancreatic cancer and translating these findings into new treatment options; 2) identifying means to sensitize tumors to radiation therapy using metallic nanoparticles to generate radiation dose-enhancement and/or hyperthermia and 3) developing nanoparticle-based molecular imaging probes to facilitate image-guided therapy.
