Philosophy of Care

I believe in a team-based approach for the development of a personalized treatment plan.

Clinical Interests

A researcher as well as a surgical oncologist, Dr. Bold is an expert in pancreatic and hepatobiliary cancers, breast cancer and the application of minimally invasive surgical techniques for patients with cancer. He has implemented a variety of minimally invasive surgical techniques to treat patients with benign or malignant tumors. These include the sentinel lymph-node biopsy procedure for women with breast cancer and a variety of laparoscopic procedures for abdominal tumors, including laparoscopic adrenalectomy, splenectomy and pancreatectomy.

Research/Academic Interests

Dr. Bold is a key member of a multidisciplinary breast cancer research team involving experts from radiology, nuclear medicine, and biomedical engineering working to improve breast cancer detection and better guide surgical intervention. He also oversees an active basic-science laboratory investigating mechanisms of resistance to traditional chemotherapy as well as testing new treatments for detecting and treating cancer.

Dr. Bold has published extensively in the areas of apoptosis, metastasis, and the cellular biology of pancreatic and lung cancers. He is an integral member of the Clinical Trials Group at the UC Davis Comprehensive Cancer Center.
