Gastroenterology clinical, basic and translational research

Profile Summary

I am a physician and gastroenterologist. My clinical experience spans over 14 years and largely involves the care of patients with gastrointestinal conditions. During this time, I have also been involved in gastrointestinal cancer research within the Tropical Gastroenterology and Nutrition Group, which is the only gastroenterology research group in Zambia. I have in the past demonstrated the ability and commitment to conduct credible clinical and translational research as evidenced by my participation in all gastrointestinal cancer research at my institution. I am also a competent endoscopist, having done more than 3000 diagnostic and therapeutic gastroscopies. In addition, I have competence in the use of confocal laser endomicroscopy with a record of more than 100 successful procedures. I can give advise on study designs, data collection and analysis.
