Todd Aguilera, M.D.

Todd Aguilera, M.D., Ph.D.
Assistant Professor
Radiation Oncology

Research Interest: Understanding and effectively targeting factors that render tumors and metastases resistant to the immune system and conventional therapy is critical to improving long-term outcomes in cancer patients. We study gastrointestinal cancers to develop new therapeutic approaches to improve anti-tumor immune responses and then aim to translate approaches to clinical trials. This approach combined with deep assessment of patient tissues could result in discoveries and improved outcomes that are much needed.
