Jude A. Okolie is an Assistant Professor of Engineering Pathways at the Gallogly College of Engineering, University of Oklahoma. His research combines experimental analysis with process design and simulation, energy system modelling and life cycle assessment to address several environmental and energy challenges. Dr. Okolie has published several research articles in the area of thermochemical and biological conversion of waste biomass into biofuels. He is a recipient of several awards in the field of thermochemical conversion processes. Emmanuel Epelle is a Chancellor’s Fellow at the University of Edinburgh’s Institute for Materials and Processes. His major scientific achievements to date are in demonstrating decontamination via oxidation processes; valorisation of waste biomass and in CFD and systems modelling. He is a Chartered Engineer, an Associate Fellow of the UK Higher Education Academy and a recipient of several research and innovation awards. Alivia Mukherjee is a postdoctoral researcher in the Department of Mechanical Engineering at the University of Alberta. She was a graduate researcher in the Department of Chemical and Biological Engineering at the University of Saskatchewan. Her research focuses on thermochemical hydrogen production, activated carbon production, and applications for environmental remediation including post-combustion CO2 capture. Alaa El Din Mahmoud is Assistant Professor in the Environmental Sciences Department, Faculty of Science at Alexandria University, Vice-Chair of the National Committee of the UNESCO-MAB (Man and Biosphere) program in Egypt, and a member of the alumni professional development unit in the Faculty of Science. He received his Ph.D. from Friedrich Schiller University Jena, Germany. His research focuses on interdisciplinary environmental issues which are related to sustainability, conservation of natural resources, water/wastewater treatment, nanotechnology, and green nanotechnology.
