Research Interests: Microbial ecology, nutrition composition of indigenous fruits, drug-drug interaction,
DNA damage and repair/Carcinogenesis.

Professor Chetsanga joined the Biochemistry Department in 1983 as a Senior Lecturer. Previously, he worked at the University of Michigan as a Full Professor of Biochemistry and Molecular Biology. He is interested in research focused on chemical carcinogenesis. This involves an analysis of both DNA damage caused by chemical carcinogens and enzymology of the damage repair. Professor Chetsanga has retired from active research activities.
