Godfrey Sikha

Research Assistant Professor

Dr. Sikha's research interests are directed towards the understanding of electrochemical power sources (batteries, fuel cells, capacitors) through mathematical modeling and experimental analyses. His recent research involves identification of suitable parallel/series combination of different electrochemical power sources (hybrid system) to suit the power and energy requirements of specific applications. His research also involves theoretical studies on Electrochemical Impedance Spectroscopy (EIS) and its utility as a tool to identify and understand reaction mechanisms, transport processes and material degradation in electrochemical systems.
