He holds MSc and PhD qualifications in natural product Pharmacology and toxicology from the University of Nairobi. In addition, He holds Postdoctoral qualifications from Noguchi Memorial Institute for Medical Research (NMIMR), College of Health Sciences, University of Ghana, where he pursued drug discovery against zoonotic tuberculosis from natural products of plant biodiversity. Specifically, He utilized whole cell assay and subcellular targets for lead compound identification and structural characterization of lead antimycobacterial compounds with rapid kill kinetics against latent, intracellular and active tuberculosis. These studies culminated in characterization of a new source steroidal sapogenin of spirostane type, solagenin (25S)-6α-hydroxy-5α-spirostan-3-one), with selective activity (SI index: 65) against the pathogenic Mycobacterium bovis (ATCC® 35720™) strain. These efforts led to publication of highly cited articles. Prior to the postdoctoral award by Bill and Melinda Gates Foundation (BMGF) through Noguchi Memorial Institute for Medical Research (NMIMR), Dr. Mwanzia Nguta was a doctoral and later a postdoctoral fellow at the Department of Public Health, Pharmacology and Toxicology (PHPT), University of Nairobi, under support from Carnegie supported Regional Initiative in Science and Education, African Natural Products Network (RISE-AFNNET) University of Nairobi Node, investigating medicinal plants for antiprotozoal activity. These studies led to high impact articles. Dr. Mwanzia Nguta has supervised three (3) Doctoral (PhD) students and fifteen (15) Master of Science (MSc) students to completion. These graduates serve in Industry, Academia and in government. He has published cumulatively fifty one (51) articles in leading peer reviewed journals.
