Research Professor, Head of the Biodegradation Laboratory for Toxic Organic Compounds, Environmental Microbiology and Biodegradation Group, Department of Environmental Protection. Our research aims to understanding the reaction mechanisms of microbes mineralizing or detoxifying persistent toxic organics, such as dioxins, PCBs, explosives, pesticides, and other recalcitrant chemical compounds. We are elucidating catabolic pathways and optimize them genetically. Editorial boards of Journal of Bacteriology (2000-2011), Applied and Environmental Microbiology (2006 - 2017).
