Jason Cooper is a research scientist at LBNL and a key member of JCAP research team. Jason’s primary focus is on understanding the electronic structure of new materials using spectroscopic and computational methods to better understand carrier physics with the goal to improve processes such as carrier recombination, transport, and energetics favorable for solar water splitting and CO2 reduction to liquid fuels.
