[3] After a year in industry, Bediako moved to the East Coast, where he joined the laboratory of Daniel G. Nocera at the Massachusetts Institute of Technology.
Bediako eventually earned his master's degree at MIT, where he worked on mechanistic studies of water splitting electrocatalysis, and the development of metal catalysts for solar energy storage.
[5] At MIT, he also worked on devices that use electricity from photovoltaic cells to generate hydrogen than can be used in fuel cells, and was part of the team who developed the components of the artificial leaf; a device which makes use of bacteria to convert solar energy into a liquid fuel.
[2][8] After completing his doctorate, Bediako remained at Harvard University as a postdoctoral research fellow in Philip Kim's group.
[2][10] By stacking materials in such a way, and embedding lithium ions between the individual layers, Bediako showed that it was possible to engineer higher electrochemical capacities.
