Research Summary

Dr. Sorbarikor Piawah is a gastrointestinal oncologist with a particular interest in colorectal cancer. She also treats patients with sarcoma, a group of rare cancers that affect the bones and connective tissues.

Piawah has a background in public health research, particularly in health care disparities among racial and ethnic minorities and low-income patients with cancer. Her current research is focused on understanding the roles that the gut microbiome (the population of microorganisms living in the intestinal tract), diet and lifestyle play in disparities among those with colorectal cancer and on designing therapies that target these factors.

Piawah earned her medical degree at Harvard Medical School and a master of public health degree at the Harvard T.H. Chan School of Public Health. She completed a residency in internal medicine at Brigham and Women's Hospital, one of Harvard's teaching hospitals. She completed a fellowship in hematology and oncology at UCSF.

Piawah belongs to the American Society of Clinical Oncology. She has received awards for her research from the UCSF Osher Center for Integrative Medicine and UCSF Center for Aging in Diverse Communities.

In her free time, Piawah enjoys painting and learning to garden.
