Nature presents man with many challenges. Most natural occurrences have their biochemical bases. Prof. Chiedozie O. Ibegbulem’s approach to research is to provide biochemical explanations to as many problems he encounters as possible. He tries as much as possible to troubleshoot and interpret his findings to the best of his abilities.
