Dr. Wesley Kidder is a gastrointestinal oncologist with a special interest in colon and rectal cancers as well as neuroendocrine tumors (cancer cells arising from the endocrine and nervous systems).

Kidder studies the role that the gut microbiome – the microorganisms that live in the digestive tract – plays in the development and treatment of colon and rectal cancers. His research includes examining the changes in the microbiome that occur following treatment with oral chemotherapy.

After earning a master of public health degree from the University of Southern California, Kidder earned his medical degree at the George Washington University School of Medicine and Health Sciences. He then completed a residency in internal medicine at the University of California, San Diego, where he served as chief resident. He completed a fellowship in hematology and medical oncology at UCSF, where he also served as the chief fellow for his final two years.
