Discovered two enzymes involved in the repair of damaged DNA:

  • Formamido-pyrimidine DNA glycosylase that removes damaged 7-methylguanine from DNA (1979).[3]
  • DNA cyclase that recloses imidazole rings of guanine and adenine damaged by x-irradiation (1985)[4].

  • Assitant Professor, Associate Professor, Full Professor, University of Michigan, 1972-1983
  • Professor of Biochemistry, University of Zimbabwe, 1983-1986

  • Pro Vice Chancellor, University of Zimbabwe, (1991-1993)[1]
  • Director General, Scientific and Industrial Research and Development Center, Zimbabwe, 1993-2003[2]
