We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

I am a board-certified medical oncologist who treats patients with gastrointestinal cancers. My specialization is in primary liver cancer (hepatocellular carcinoma), pancreas, gallbladder, and bile duct tumors. As part of a multidisciplinary group, my colleagues and I offer patients a team approach to treating these cancers.

My research focuses on improving the effectiveness of cancer therapy by incorporating small novel biological molecules that target cancer into the treatment of chemotherapy-resistant gastrointestinal malignancies, particularly hepatobiliary and pancreatic cancers.
