Our Research
Our research centers on microorganisms capable of extracellular electron transfer, allowing them to interact with electricity in unique ways. By studying these microbes — such as cable bacteria — we aim to harness their properties for applications in environmental sustainability, including pollution mitigation, carbon sequestration, and restoration of ecosystems.
Microbial Fuel Cells
Microbial Fuel Cells (MFCs) are bio-electrochemical systems that drive electric current by using bacteria as a catalyst to oxidize organic and inorganic matter. Our research focuses on advancing the efficiency and applicability of MFCs in sustainable energy generation.
A Benthic Microbial Fuel Cell (BMFC) is a specialized design deployed in the benthic zone of aquatic environments, enabling long-term, sustainable power generation for underwater applications.

Cable Bacteria: Living Wires Electrify the Mud
Cable bacteria are long filamentous bacteria capable of conducting electrons over centimeter distances. We study their ecology and potential applications in environmental bioremediation and energy harvesting from sedimentary environments.
