Biography

Jovine Kamuhabwa Emmanuel is a Senior Lecturer of Physical Chemistry since August 2023 in the Department of Chemistry at Mkwawa University College of Education of the University of Dar es Salaam, Tanzania. He specializes in heterogeneous catalysis using nanoparticles, and materials sciences. He earned his Doctorate in Chemistry from the University of Southampton, United Kingdom (2015), Master of Science and Bachelor of Science (Chemistry & Biology) with Education from the University of Dar es Salaam, Tanzania in 2007 and 2011, respectively. During his Ph.D programme, he investigated titania supported gold and platinum nanoparticles size effects in the oxidation of carbon monoxide in the State-of-the-Art High Throughput Combinatorial Laboratory for materials discovery, synthesis and optimization under Professor Brian Hayden. Besides, he has investigated the metal corrosion inhibition in acidic media using natural corrosion inhibitors at the University of Dar es Salaam during his Master of Science Programme under Professor Joseph Buchweishaija. Currently, he is working on bioenergy generation including biogas and bioethanol from bio-wastes with emphasis on circular economy. He has received several awards in his research career including the recent University of Dar es Salaam’s distinguished innovator of the year 2024. His research interests include heterogeneous catalysis, nanomaterials and nanofabrication, metal corrosion inhibition using natural corrosion inhibitors, bioenergy sources, and bioenergy generation from bio-wastes. Jovine is passionate about making a positive impact on improving human life and health through generation of clean and sustainable energy sources, an alternative to fossil fuels in addition to promoting circular economy and environmental conservation. He has widely published in metal corrosion inhibition, heterogeneous catalysis and biofuels generation (https://orcid.org/0000-0002-2580-1539).
