David Mark Kramer

David Mark Kramer is the Hannah Distinguished Professor in the Department of Biochemistry & Molecular Biology and the MSU-DOE Plant Research Laboratory at Michigan State University. He is affiliated with the Molecular Plant Sciences Program and focuses on understanding how plants convert light energy into usable forms for life, balancing photoprotection with photochemical efficiency, and adapting to extreme environments.

Education:

• Ph.D. in Biophysics (1990), University of Illinois
• M.S. in Cell Biology (1986), University of Dayton
• B.S. in Biology, University of Dayton

His research investigates the energetics and control of photosynthesis reactions, emphasizing electron and proton transfer mechanisms, reactive oxygen generation, and the role of proton motive force in ATP synthesis and photoprotection. Techniques include spectroscopy (absorption, fluorescence, circular dichroism, EPR) applied to isolated membranes, organelles, and intact plants.

Scientific Awards:

• Hannah Distinguished Professor

The Kramer Lab develops novel spectroscopic tools to monitor photosynthesis in vivo, aiming to validate molecular models under natural conditions and advance applications in plant breeding and precision farming. His work bridges molecular mechanisms with ecological and agricultural impacts.
