Chloe Atreya, MD, PhD

Gastrointestinal oncologist

Dr. Chloe Atreya specializes in gastrointestinal cancer, particularly colorectal cancer, at the UCSF Helen Diller Comprehensive Cancer Center. Her research focuses on the interplay of tumor genetics and a patient's response to therapies for colorectal cancer, with the goal of improving patient outcomes by personalizing therapy.

Atreya received her medical degree and Ph.D. in pharmacology at Yale University. Subsequently, she completed her internship and residency in internal medicine at University of Washington, Seattle and fellowship in medical oncology at UCSF, where she is now assistant clinical professor. Atreya is the recipient of numerous prestigious awards, including the American Cancer Society Postdoctoral Fellowship, Conquer Cancer Foundation of the American Society of Clinical Oncology Young Investigator Award and Alliance for Clinical Trials in Oncology Foundation Investigator Award. She is a member of the American Society of Clinical Oncologists, American Association of Cancer Researchers and Alliance for Clinical Trials in Oncology, Gastrointestinal Committee.
