Biography

Dr. James C. Liao is a pioneer in Metabolic Engineering, Synthetic Biology, and Systems Biology. He received his B.S. degree from the National Taiwan University and Ph.D. from the University of Wisconsin-Madison. After working as a research scientist at Eastman Kodak Company in Rochester, N.Y., he started his academic career at Texas A&M University in 1990 and moved to UCLA in 1997. He was elected Fellow of the American Institute for Medical and Biological Engineering in 2002 and has received numerous awards including the NSF Young Investigator Award (1992), Merck Award for Metabolic Engineering (2006), FPBE Division award of American Institute of Chemical Engineers (AIChE) (2006), Charles Thom Award of the Society for Industrial Microbiology (2007), Marvin J. Johnson Award of the American Chemical Society (2009), Alpha Chi Sigma Award of AIChE (2009), James E. Bailey Award of the Society for Biological Engineering (2009), and Presidential Green Chemistry Challenge Award (2010).

Research Interest

Biomolecular & Metabolic Engineering

Our research has focused on metabolism, including its biochemistry, extension, and regulation. We use metabolic engineering,synthetic biology, and systems biology to construct microorganisms to produce next generation biofuels and to study the obesity problem in human. We also develop mathematical tools for investigating metabolism and guiding engineering design. Currently, our main projects include engineering proteins and biochemical pathways for CO2 fixation and produciton of fuels and chemicals. Our ultimate goal is to use biochemical methods to replace petroleum processing and to treat metabolic diseases.
