Fabian I. Ezema is a Professor at the University of Nigeria, Nsukka. He obtained a PhD and MSc in Physics and Astronomy from the University of Nigeria, Nsukka, and a BSc from the then Anambra State University of Science and Technology, Enugu. His researches are on several areas of Materials Science: synthesis and characterizations of particles and thin films materials through chemical routes with emphasis on energy applications. He is interested in materials for thin film solar cells fabrication and nanoparticle synthesis. For the last 15 years, he has been working on the nano/submicron-sized materials for energy conversion and storage (cathodes, anodes, supercapacitors, thin film solar cells, DSSC, etc.), including novel methods of synthesis, characterization, and evaluation of the electrochemical and optical properties. He was a CV Raman Fellow at the Shivaji University, Kolhapur, India, in 2011 and MIF Fellow at Tokyo University of Science, Japan, in 2013. He is avisiting professor to NRSEMT (MATECSS UNESCO Chair) in Varennes, Quebec, Canada, and iThemba Labs, South Africa. He is also a Fellow of UNESCO-UNISA South Africa Chair in Nanosciences and Nanotechnology (U2ACN2). He was awarded the University of South Africa (UNISA) visiting researcher program (VRP). Fabian is a senate representative to National Center for Energy Research and Development (NCERD), University of Nigeria, and due to his commitment to research and international visibility was appointed Pioneer Acting Director, International Office of the University of Nigeria after the approval of the office by the University Senate. He has served as Coordinator, Natural Science Unit, School of General Studies, UNN. He is the Coordinator of Nano Research Group, University of Nigeria, Nsukka. He is the pioneer Dean, Faculty of Natural and Applied Sciences, Coal City University Enugu, Nigeria.
