Research Summary

Early plants began colonizing the terrestrial earth approximately 450 million years ago. Their success on land has been attributed to the evolution of elaborate specialized metabolic systems from core metabolic pathways, the former yielding a panoply of functionally diverse chemicals to cope with a myriad of biotic and abiotic ecological pressures.

Our lab has broad interests in understanding the origin and evolution of plant specialized metabolism at enzyme, pathway, and systems levels, as well as how plants exploit discrete small molecules to interact with their surrounding biotic and abiotic environments. Our work in plant metabolic evolution impacts a fundamental question in biology - how do complex traits evolve in a Darwinian fashion? In addition, we actively seek opportunities to utilize plant as a unique model system to study human diseases, including metabolic syndromes and protein-misfolding diseases. In the long run, we also aim at elucidating the molecular mechanisms underlying the "matrix effect" known from many traditional herbal remedies used for thousands of years. We believe that basic scientific research motivated by curiosity will be key to address the societal challenges of tomorrow.

Current topics of interest for the lab include:

  • Hormone metabolism, biased ligands, and complex signaling
  • Structural, energetic, and mechanistic determinants of enzyme evolvability
  • Molecular mechanisms associated with protein misfolding in plants
  • Personalized cocktail medicine inspired by traditional herbal remedies
