Research Director

Dr. Meng’wa is lecturer in Physics at Alupe University. He has been the Chair, department of Mathematics, Physics and Computer Science since Jan. 2019 to date. He also serves as Research director of Alupe University. His postgraduate studies begun in 2010 after enrollment of Master of Science program degree in Physics at University of Eldoret. At UoE, he was an MSc student, Physics Research Assistant and Tutorial fellow. He was awarded MSc (Physics) degree in 2014. He got admitted for PhD in Physics from 2016 in University of Eldoret and did sandwich PhD program between University of Eldoret and International Centre of Theoretical Physics, ICT (Trieste, Italy). He graduated with PhD (Physics) in November 2018.

My research interests are in computational material science for renewable energy applications, DFT atomistic simulations and photo/electro catalysis on nanostructured metal oxides. At the moment, my research works entail CO₂ electrocatalytic reduction at nanostructured copper oxides on TiO₂ (101) anatase surface and alloying Cu for enhanced CO₂ Electro-reduction. My collaborators are Computational Material Science group in University of Eldoret and Moi university. I also maintain contacts and working relationship with CMSP (Materials for Renewable energy) researchers in ICTP, Trieste, Italy and CMMIS.
