I am a medical gastroenterologist and faculty member of the University of Zambia School of Medicine. I am a founding fellow of the East, Central, and Southern African College of Physicians, current president of the Zambia College of Gastroenterology and Nutrition and I served as treasurer for the Zambia College of Physicians. I am also a member of the African Organisation for Research and Training in Cancer and one of the founding members of the recently formed African Oesophageal Cancer Consortium. My main research interests are in upper gastrointestinal cancers. As a faculty member of the University of Zambia School of Medicine, I intend to continue contributing towards improved research output from sub-Saharan Africa.
