Robert Blankenship

Robert Blankenship’s research focuses on understanding the mechanism of energy-storing reactions in photosynthetic organisms, as well as understanding the origin and early evolution of photosynthesis. His research group studies almost every group of photosynthetic organism, including both anoxygenic and oxygenic photosynthetic bacteria, algae and higher plants, as well as some nonphotosynthetic bacteria.

The chemical reactions leading to long-term energy storage in photosynthetic systems take place within the membrane-bound reaction center complex and an associated group of proteins that make up an electron transport chain. One of the central goals is to identify the molecular parameters responsible for the fact that essentially every photon absorbed by the system leads to stable products. To better understand this, his lab performs a variety of kinetic, thermodynamic and structural measurements on antenna complexes, reaction centers, electron transport proteins and isolated pigments, using a number of techniques, including ultrafast laser flash photolysis and UV-VIS, fluorescence and electron spin resonance spectroscopies, as well as biochemical and molecular biological analysis, mass spectrometry and X-ray and neutron crystallography.
