The Beck Laboratory

Professor Warren F. Beck

We are studying photophysical and photochemical processes in photosynthetic light-harvesting proteins and relevant model systems using femtosecond multidimensional spectroscopy. Our current focus is on carotenoid-containing proteins, including the peridinin–chlorophyll a protein from dinoflagellates and the orange carotenoid protein from cyanobacteria.

1 January 2015. Installation of a new femtosecond laser system, consisting of a high-repetition rate Yb amplifier (Spectra-Physics Spirit), computer controlled noncollinear parametric amplifier (NOPA, Spectra-Physics Spirit-3H), and a pair of adaptive pulse shapers (Biophotonics Solutions FemtoJock and FemtoJockP). The system was obtained with funds provided by the Office of the Vice President for Research and Graduate Studies at Michigan State University.
