Education and Research

Biographic summary
Dr. Masa earned a doctorate (PhD), with a distinction, in Natural Sciences (Dr. rer. nat) from Ruhr-University Bochum (Germany) in 2012 under the supervision of Prof. Dr. Wolfgang Schuhmann, a M.Sc. degree in Chemistry (2008) from Makerere University, and a B.Sc. degree, Industrial Chemistry major (2003), also from Makerere University. He was a Visiting Scholar in the Physical and Theoretical Chemistry Laboratory at the University of Oxford in the summer of 2013 and worked in the Research Group of Prof. Richard G. Compton. In January 2014, he returned to Ruhr-University Bochum as a Postdoctoral Researcher, and later rose to the position of a Senior Research Scientist and Leader of the Electrocatalysis and Energy Conversion Group in the Department of Analytical Chemistry and Center for Electrochemical Sciences (CES). He is a co-inventor of four patents, one of which was sold to Bayer - materials division (Germany). Two of these patents were selected among the best inventions at Ruhr-Universities in 2010 and 2014. His core research is in the field of electrocatalysis and energy conversion, especially the rational design of advanced low-cost catalysts and electrode materials for electrochemical energy systems, from portable applications to Grid-level energy storage, including fuel cells, electrolyzers (power to gas energy conversion), rechargeable metal-air batteries and supercapacitors. He is a co-author of two book chapters and has at least 50 peer-reviewed scientific papers in international journals, with a total of 1105 citations, H-index = 21, i10-index = 28 in google scholar records, as of 27.01.2017. He serves a regular reviewer for highly esteemed journals in Chemistry, including: Journal of the American Chemical Society, Journal of Physical Chemistry, Journal of Physical Chemistry, Angewandte Chemie International Edition, ChemSusChem, ChemCatChem, Electrochemistry Communications, Journal of Catalysis, Electrochemica Acta, Energy Technology, Journal of Solid State Letters, Journal of the Electrochemical Society, Applied Catalysis A, Carbon, Journal of Power Sources, and the Journal of Electroanalytical Chemistry, among others.
