My long-term research goals are to understand how photosynthetic energy conversion works, how it is regulated, and how it might be improved to help meet the world’s needs for food and fuel. We use a wide array of experimental organisms and interdisciplinary approaches to investigate fundamental questions about assembly, regulation, and dynamics of photosynthesis. Current lab members study the biosynthesis and function of photosynthetic pigments, assembly and repair of photosynthetic reaction centers, structure and dynamics of the photosynthetic membrane, mechanisms involved in sensing excess light, singlet oxygen signaling, transcriptional regulation of photosynthesis and photoprotection by light and carbon, and regulation of photosynthetic light harvesting in saturating light. By comparing how photosynthesis works in diverse organisms, we hope to uncover general design principles of natural photosynthesis as well as unique adaptations to different environments.
