Biography

Jiajie Xu is a Professor at the School of Marine Sciences, Ningbo, China. He obtained his Ph.D. in 2009 from China Agricultural University, where he studied biomass conversion technology. He then worked with Professor Largus Angenent as a postdoctoral researcher at Cornell University, focusing on waste carbon recovery through chain elongation processing under anaerobic conditions. After that, he moved to Saudi Arabia and joined Professor Pascal Saikaly at KAUST, where he worked on the discovery of chain elongation microbes from special environmental conditions. Currently, his research interests primarily focus on wastewater treatment and resource recovery.
