Xuan Wang is a microbiologist interested in developing new microbial fermentation processes for the production of renewable bio-based chemicals. He received his BS from University of Science and Technology of China and obtained MS from Chinese Academy of Sciences (CAS) wtih CAS President Award. He obtained his PhD from University of Michigan with the support of Rackham Predoctoral Fellowship before he moved to University of Florida for his postdoc training in metabolic engineering. His lab at ASU combines genetics, experimental evolution and metabolic engineering in a concerted effort to address two great challenges in the field of applied microbiology. First, how to increase the carbon utilization efficiency of microbes when using renewable carbon sources; and second, how to optimize bacterial transport systems for bio-based production. In addition, he is also interested in altering and expanding cellular metabolisms to produce new value-added chemicals.
Education
Ph.D. Molecular, Cellular, and Developmental Biology, University of Michigan, Ann Arbor, 2008
M.S., Biochemistry, Chinese Academy of Sciences, 2003
B.S., Biological Science, Univ. of Sci. & Tech. of China, 2000
Our lab aims to design and engineer recombinant microorganisms to produce valuable chemicals from renewable sources with the potential to replace petroleum-derived counterparts. Currently we are striving to characterize and overcome metabolic constraints and transport barriers that limit microbial production. Deep understanding of microbial metabolism, experimental evolution and metabolic engineering are our tools to achieve these goals.
