Research in the Chen lab is centered around functional genomics of plant metabolism. Collectively plants produce a huge diversity of metabolites that are known as secondary metabolites or natural products. These metabolites play important roles in plant biology and ecology. They may be involved in plant defenses against insects and pathogens, attracting pollinators, or providing resistance to abiotic stresses. In addition, plant secondary metabolites are important for human health, where their application may range from medicines to functional food. Despite its importance, plant secondary metabolism in general remains poorly characterized. The research program in the Chen lab focuses on using an integrated genomics approach, which combines bioinformatic analysis, metabolomics, transcriptomics, and large-scale in vitro biochemical assays, to systematically discover novel genes of plant secondary metabolism. Furthermore, we are interested in using metabolic engineering to alter the production of certain secondary metabolites for crop improvement, such as to enhance plant natural defenses and improve the quality of fruits, flowers and biofuel feedstocks.
