Biography:

Prof Christopher Chintua Enweremadu attended the Odessa Technological Institute of Food Industry, (now Odessa National Academy of Food Technologies, Odessa, Ukraine) where he obtained Integrated MSc, Mechanical Engineering with specialisation in Food Processing Machines & Equipment in 1994. He lectured at the Ladoke Akintola University of Technology, Ogbomosho, Nigeria from 1995 to 2008. After obtaining PhD in Mechanical Engineering (Heat & Mass Transfer) in 2008 at the Ladoke Akintola University of Technology, he was awarded a postdoctoral research fellowship at the Tshwane University of Technology, Pretoria. On completion of the research fellowship, he was appointed as a Senior Lecturer at Vaal University of Technology, Vanderbijlpark where he worked from November 2009 to December 2011. Prof Enweremadu joined the University of South Africa in 2012.

Prof Enweremadu is an NRF C3 rated researcher who has published over 50 journal articles (in the areas of bioethanol, biodiesel, biogas, solar radiation, solar PV cleaning for soiling mitigation). He has also published over 20 papers in reputable peer-reviewed conferences and five book chapters. From 2015-2017, Prof Enweremadu served as a member of editorial board of the International Journal of Oil, Gas and Coal Technology, an ISI-indexed journal.

Prof Enweremadu is a regular reviewer for high-impact journals, reputable conference proceedings and book chapters. As a result of the quality of his reviews, he has been awarded Elsevier Certificates of Outstanding Contribution in Reviewing by the journals: Energy, Applied Energy, Energy for Sustainable Development and Journal of Cleaner Production. He has served in National Research Foundation (NRF) panels and has reviewed grant-funding and researcher rating applications for her and other international grant-awarding organisations.

Prof Enweremadu is an experienced teacher/lecturer who has taught various courses in Mechanical and General Engineering in Nigeria and Kenya (as an adjunct). He is a member of the American Society of Mechanical Engineers (ASME), South African Institution of Mechanical Engineering (SAIMECHE), World Society of Sustainable Energy Technologies (WSSET), Nigerian Society of Engineers (NSE) and a registered engineer with the Council for the Regulation of Engineering in Nigeria (COREN).
