Phytochemistry, Metabolic Engineering



 Research Interests:


The research interests in my laboratory focus on the understanding of the structure, origination, biosynthesis and regulation of plant natural products. Currently, my lab is working on two major groups of natural products, the flavonoids and sesquiterpenoids. We are using a combinatorial approach that includes phytochemistry, metabolomics, molecular biology and biochemistry to understand their structures and biogenesis of these componds. We are applying our findings to modify plants (i.e. food and forage crops) to improve the production of important natural products or produce novel natural products through metabolic engineering. In addition, we are interested in establishing novel approaches to screen for natural anti-cancer and anti-malaria products
