Nikolaos Xafenias

Forskare at Chalmers, Biology and Biological Engineering, Industrial Biotechnology

Dr. Nikolaos Xafenias is a researcher at the Department of Biology and Biological Engineering. His research focuses on the sustainable production of valuable chemicals and fuels, and the recovery of nutrients from wastewater streams. He is mainly working with bioelectrochemical systems, devices where whole microbes are utilized to catalyze electrochemical reactions. By merging wastewater treatment, anaerobic digestion, and microbial electrosynthesis processes, the overall aim is to develop novel methods and promote biorefinery-based alternatives for the energy and chemical industries.
