Biography

I started my research career as a M.S. student focusing on nanomaterial, carbon adsorbents and catalysts in 1997, when I was a major pioneer of photocatalysis technology in China. After 2001, my PhD research focused on bio-separation technology, especially recombinant protein purification. In 2004-2006, I developed the first three-dimensional protein (size, surface charge and hydrophobicity) characterization methods and applied this innovative method to a complex Corn extract protein. After completed my PhD study, I joined GE-Lifescience Fast Trak as lead applicant scientist, managed typical training courses about biopharmaceutical processing development, as well as lead customized biopharm downstream processes development service team in Shanghai. In 2008 March, I moved back to academic for more research freedom and innovative, and joined Microbiology department at University of Illinois as a Postdoc. In this short postdoc period, I solved multiple critical challenges in expression and purification of the new botulinum neurotoxin therapeutical delivery vehicle.

Since I joined ABE department at SDSU in Dec. 2008, multiple disciplines background and experiences enable my research more flexible in current intensively competitive environment. Since 2010, my interest started to focus on biorenewable advanced carbon materials, electrochemical energy storage devices and functional adsorbents for biofuel separation in biorefinery. Our recent biorenewable carbon materials work has led us to prepare multiple advanced carbon materials from different biomass as well as evaluated these carbon materials’ energy storage function in electrochemical supercapacitor and lithium ion batteries. Our subsequent work showed that a novel nitrogen doped 3D graphene, which demonstrated excellent electrochemical properties as electrode materials of supercapacitor, was synthesized from distiller’s dried grains with solubles (DDGS) with a facile low temperature catalytic graphenization process. In addition, we have developed multiple methods to control surface oxygen and hydrophobicity of carbon adsorbents for improving electrochemical energy storage properties, as well as enhancing adsorption selectivity for biofuel harvesting. Recently, I also started to integrate bioseparation techniques and graphene materials into a new biosensor platform, and explore next generation high selective and high conductive disposable probes of electrochemical biosensor devices.
