Biography

Biography

Dr. Jovine Kamuhabwa Emmanuel is a Senior Lecturer in Physical Chemistry at the Department of Chemistry, Mkwawa University College of Education, University of Dar es Salaam, Tanzania, a role he has held since August 2023. His expertise lies in heterogeneous catalysis using nanoparticles, materials science, and biofuel sources and production. He teaches a range of Physical Chemistry courses including chemical thermodynamics, chemical kinetics and electrochemistry, physical chemistry, fuel chemistry, and chemical separation techniques.

Dr. Emmanuel earned his Ph.D. in Chemistry from the University of Southampton, UK, in 2015, where he investigated the size effects of titania-supported gold and platinum nanoparticles in carbon monoxide oxidation under the supervision of Professor Brian Hayden in a cutting-edge high-throughput combinatorial laboratory. He also holds a Master of Science in Chemistry (2011) and a Bachelor of Science with Education in Chemistry and Biology (2007) both from the University of Dar es Salaam. His MSc research focused on metal corrosion inhibition in acidic media using natural inhibitors under Professor Joseph Buchweishaija.

Before embarking on his academic career, Dr. Emmanuel served as a Fisheries Officer II (Fish Inspector) at the Ministry of Natural Resources and Tourism in Tanzania (2007), working both at the headquarters in Dar es Salaam and in the Lake Victoria Zone in Mwanza. This experience enriched his understanding of environmental systems and resource management which continues to inform his research and teaching.

Currently, his research centers on bioenergy generation including biogas, bioethanol, and biodiesel from bio-wastes and bio-substrates with a strong emphasis on circular economy principles and nutrient recovery. Driven by a passion for sustainable development, Dr. Emmanuel seeks to enhance human health and environmental conservation through clean energy alternatives to fossil fuels.

He has authored and co-authored 30 peer-reviewed publications in areas such as metal corrosion inhibition, heterogeneous catalysis, and biofuels including a record of over 17 articles published in reputable journals in 2025. Since earning his Ph.D., he has taught extensively at Mkwawa University College of Education and supervised more than six MSc students and one Ph.D. candidate. His achievements have earned him prestigious honors including the University of Dar es Salaam’s Distinguished Innovator of the Year 2024 and First Prize in both Best Innovator and Research Excellence categories during the 10th University of Dar es Salaam Research and Innovation Week at Mkwawa University College of Education in 2025. His ORCID profile is available at https://orcid.org/0000-0002-2580-1539.
