About the Investigator

Dr. Sharaf is a gastroenterologist with a clinical focus on the care of patients with hereditary gastrointestinal cancer syndromes. His experiences in genetics, gastroenterology, health services research, and clinical-guideline development have led to a singular career goal. Dr. Sharaf aims to become an independent health services researcher who studies the comparative effectiveness of cancer prevention and treatment strategies, refines cancer risk and prognosis estimates, and develops evidence-based practice guidelines and quality metrics. His wish is to develop particular expertise in decision analysis and Markov modeling, as it relates to cancer.
