Dr. Karthikeyan Rengasamy is a staff scientist in the Bose lab. He received his Ph.D., in microbial electrochemical technology from the Central Electrochemical Research Institute in India. He has acquired experience in the characterization of electroactive biofilms using various electrochemical analytical techniques to understand microbial electron transfer. Currently, Dr. Rengasamy is working on various novel aspects of photosensitive microbes with charged electrodes. His research focuses on understanding electromicrobiology under different environments including light, dark, freshwater, seawater, and various wetland soils. Dr. Rengasamy is interested to study the mechanism of bio-interfaces wherein microbial respiration and metabolic reactions are occurring at the electrode/mineral surfaces in a micro-sized bio-electrochemical system.
