Our group believes that studying chemical and biophysical systems via single-molecule techniques is a profound and absolutely delightful way of doing science. We use single-molecule methods to study chemical reactions such as homogeneous catalysis, biophysical processes such as protein folding, and materials properties such as energetic disorder in photovoltaics. We build instruments, synthesize molecules, fabricate nanophotonic devices, and are trying to make some really exciting new measurements.
