Biographic summary

Dr. Masa earned a doctorate (PhD), with a distinction (summa cum laude), 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 at

the Center for Electrochemical Sciences (CES) in the Department of Analytical Chemistry. He is

a co-inventor of four patents, three of which won the award for the best innovations at Ruhr-

University Bochum in 2010, 2014 and 2017. Dr. Masa was recently selected a as fellow of the

Next Einstein Forum (NEF) for the 2017-2019, a recognition of Africa’s most outstanding

scientists. 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 stationary mini-grid and grid-level energy storage, including

fuel cells, electrolyzers (power to gas energy conversion), rechargeable metal-air batteries and

redox flow batteries. He is a co-author of two book chapters and has published at least 70 peer-

reviewed scientific papers in international journals.
