Dr. Zarchy's major areas of research interest are outcome studies regarding use of colonoscopy and sigmoidoscopy for finding advanced colon neoplasms; inflammatory bowel disease in low socioeconomic populations. Currently he is a Principal Investigator in an IRB approved study of the utility of rectal bleeding, +FOBT and iron deficiency anemia as indications of colonoscopy versus analysis of demographics and genetics of Roybal and IBD patients with regard to Crohns vs. UC and the severity of UC.
Dr. Zarchy earned his medical degree from George Washington University. He performed his residency at Veterans Administration Hospital and Georgetown University Hospital. He stayed on to complete his Gastroenterology and Hepatology Fellowship.
