Research Interests


Our group uses genetic, genomic and biochemical approaches to understand the regulation of biosynthetic pathways of importance to flowering plants and the animals that depend on plants for sustenance. Plants synthesize an enormous number and variety of primary and specialized (‘secondary’) metabolites. Many have documented or proposed roles in homeostasis (hormones, for example), interaction with other organisms (pathogens, symbionts, and herbivores), and defense against harmful non-biological stress agents (cold, drought, light, oxidizing chemicals, etc). In addition, plants are primary sources of nutrients essential to humans and other animals (for examples: vitamins, essential amino acids, and minerals), pharmaceuticals, and phytochemicals with proposed health-promoting value (antioxidants, phytosterols, glucosinolates, etc). Recent quantum leaps in structural and functional genomics coupled with breakthroughs in mass spectrometry-based analytical chemistry have created unprecedented opportunities to rapidly increase our understanding of how plants synthesize these diverse and important compounds.
