Yusuf Hamied Department of Chemistry


Research Associate

Mohammed’s research interests focus on understanding the underlying electrochemical processes in electrochemical energy storage and conversion systems. He studies interfacial, charge/mass transfer processes utilizing electrochemical methods, primarily Electrochemical Impedance Spectroscopy (EIS). He also works on developing linear and non-linear EIS techniques for characterization of various battery systems. He aims to contribute to both material development and the advancement of electrochemical energy storage and conversion applications.

Currently, he studies the interfacial processes of Na-ion battery electrodes utilizing novel electrolytes. He also investigates the charge transfer mechanisms in cathode materials of Li-ion batteries and participates in collaborative projects that research electrochemical processes and develop novel electrode materials of metal ion batteries.
