Born in Shanghai, I grew up in Zhejiang Province, China. I obtained BS (1997) and MS (1999) in chemical engineering at Tianjin University in China. My MS thesis was on riboflavin fermentation and purification (advisor Xue-Ming Zhao). I did my PhD at University of Washington (1999~2004), where my study focused on marine bioremediations (advisor Barbara Krieger-Brockett). My postdoc research was at Lawrence Berkeley National Laboratory (advisor Jay Keasling). I have worked at Washington University since 2008.
