Ram Deivanayagam, Ph.D.
Battery Materials Researcher | Experimental Electrochemist
I'm a battery materials researcher and a lead scientist at Wildcat Discovery Technologies. I hold a Ph.D. from the University of Illinois Chicago in mechanical engineering with a focus on materials development for lithium-ion and beyond-lithium-ion batteries. My Ph.D. research at the NanoEngineering Lab dealt with developing solid polymer composite electrolytes for lithium and magnesium batteries and evaluating their performance in lab scale.
Before my Ph.D., I worked at the Nanomaterials and Energy Devices Lab of the Indian Institute of Science Education and Research, Thiruvananthapuram, where I completed my Master's thesis on nanostructured transition metal oxide electrode materials for lithium-ion and sodium-ion batteries.
