Raymond Weitekamp leads the polySpectra team at Cyclotron Road, a startup accelerator at Lawrence Berkeley National Laboratory. His interdisciplinary work is focused on the interactions of light with polymeric materials, including block copolymer photonic crystals and photoinitiated catalysis. While his interests are diverse, the common goal of his research is to apply fundamental scientific insights to challenges in sustainability and energy.
