Biography

Ruozhu Feng joined PNNL in 2018 as a Post-Doctorate Research Associate. Her work focuses on the development of new redox-active organic molecules for aqueous flow batteries. This research spans from synthetic methodology, fundamental electrochemistry, to the optimization of flow cell conditions and cell assembly. During her Ph.D. study under instruction by Prof. Kevin D. Moeller, her research centers on the development of new organic electrochemical methodology and understanding the mechanistic parameters that govern the success of those methods.
