Personal profile

Profile information

I am an Associate Professor in Bio and Circular Economy. My research group focuses on circular economy innovation by developing low-carbon clean technologies for waste management and carbon-neutrality based on multidisciplinary sciences in environmental and energy engineering, thermochemical and physicochemical processes, chemical reaction engineering, materials design and applied catalysis. I have been exploring energy-efficient processes, technologies, and catalysts for energy conversion and nutrients recycling of sewage sludge, sustainable disposal of municipal solid wastes, bio-refinery of biomass wastes, and technology-critical elements recovery from hyperaccumulators in terms of fundamental sciences, key reaction processes, industrial applications and commercialization. I have made innovative contributions to sewage sludge treatment pertaining to cleaner energy production, nutrients (e.g., nitrogen and phosphorus) recovery, stabilization of heavy metals. Our research was awarded 2015 Applied Energy Award and the relevant article has been listed as ESI highly cited paper every year thereafter.
