PNNL

Bo Peng obtained his BS in chemistry from Nankai University in 2005, and his PhD in theoretical chemistry from the University of Washington in 2016. He then joined PNNL as a Linus Pauling fellow in 2016, working on the development of low-scaling coupled cluster approach and its related high-performance computing library. In 2019, he transitioned to staff scientist in the Physical and Computational Science Division. His research focuses on the developments and applications of many-body theories and their advanced computational approaches and libraries. He frequently partners with the Department of Energy Office of Science, Basic Energy Sciences program.
