Expert Summary

I obtained my doctoral degree in agriculture in 2012 from the Tshwane University of Technology (TUT) in Pretoria, South Africa. After graduating, I have served as a postdoctoral researcher at both TUT and University of South Africa (UNISA). As a postdoc, I successfully supervised postgraduate students (two Honours, six master's and two PhDs) to completion at UNISA. In 2020, I was appointed as a Lecturer at the Njala University (NU) and so far, I successfully supervised undergraduates (16) to completion in the School of Agriculture and Food Sciences and currently, 15 postgraduates, and 16 undergraduates (10 (BSc.) and 6 (HND)) are under my supervision. I published six (6) research articles in accredited journals, one (1) proceeding paper, another research paper (one) is in press and three (3) more are under review. So far, I have over 30 papers published in accredited journals -See below list of peer-reviewed research publications.
