Next Generation Membrane Materials for Energy-Efficient Separations

School of Chemical & Biomolecular Engineering, Georgia Institute of Technology, Atlanta, GA 30332

My research work focuses on the creation of novel high performance membranes with advanced functional structures using tunable polymers and nanostructured materials for membrane-based gas separation, water purification, and renewable energy production. I completed my PhD on biofuels purification by pervaporation-based membrane process at Chinese Academy of Sciences and accepted a position as Assistant Professor in the same institute on hybrid fermentation/pervaporation integrated processes. In 2012 I joined Koros Research Group as a Laboratory Manager and Research Engineer at Georgia Institute of Technology. During my work with Professor Koros, I broadened my interests in Energy Efficiency and Environmental Sustainability but maintained a focus on advanced membrane materials for low energy intensive large scale separation processes.

Currently, I am a Research Engineer & Senior Project Manager at Koros Research Group at Georgia Tech, where I am further expanding my expertise in membrane-based gas separation by engineering tunable membrane materials. As a Laboratory Manager (Senior Project Manager after October 2014), I also provide mentorship and instruction to undergraduates, PhD students and post-doctoral fellows in a group of over 20 researchers since 2012. This position expanded my expertise from dense films and asymmetric flat-sheet membranes to high performance hollow fiber membranes, and also from membrane-based separations to combined hollow fiber sorbents adsorption and membrane-based coupled separations. Using advanced crosslinkable polymers, functionalized polymers of intrinsic microporosity (PIMs), and commercially available polymers, I have created advanced membranes for energy intensive industrial separations including natural gas purification, hydrocarbon separations, CO2 capture, and renewable energy production.

My future research will address both fundamental issues and applied research related to membrane-based gas separations, CO2 capture, and organophilic pervaporation membrane technology for renewable energy production. My knowledge of material properties enables me to engineer advanced polymer structures to produce economical high performance membranes to enable global CO2 reduction, energy conversion, and clean technology in diverse industrial applications.
