Krishna Katuri, Ph.D.

Research Scientists

Senior Research Scientist

Research Interests

​Dr. Katuri’s research focuses on “underpinning anaerobic microbial oxidations for sustainable resource recovery (H2 and water) from wastewaters, based on electron transfer between electroactive biofilms and carbon surfaces”. His interdisciplinary microbial-mediated resource recovery research links microbiology, electrochemistry, molecular microbial ecology and membrane science with applications in engineered electrochemical membrane biofilm reactors.
