Biography

Dr. Cesar I. Torres is an Assistant Professor of Chemical Engineering in the School for Engineering of, Matter, Transport and Energy at Arizona State University and part of the Chemical Engineering and the Civil, Environmental and Sustainable Engineering Graduate Program faculties. Cesar is a leader in microbial electrochemical cell research, focusing on microbial kinetics of anode-respiring bacteria (ARB) and extracellular electron transport to and from solid electrodes. He has published 15 articles in peer-reviewed journals on this topic. Cesar combines biofilm modeling, electrochemical, microscopic, and analytical techniques, to characterize ARB kinetics and thermodynamics.
