Ferguson Research Profile

Andrew Ferguson is an NREL Senior Scientist in the Chemistry & Nanoscience Center and Group Leader for Spectroscopy and Photoscience, and serves as a reMIND Associate Director. As part of reMIND, he will lead cross-cutting transient and in-situ spectroscopy studies and will facilitate interfacing between REMIND and NREL management and EH&S.

Research

Andrew Ferguson’s expertise is in the spectroscopic characterization of dynamic processes in electronic materials, including development and application of non-contact techniques to probe transport phenomena. In recent years, he has also focused on applying chemical redox doping approaches to control charge transport for energy conversion, as well as on developing novel chemical/material systems for optical and electrical switching phenomena relevant to neuromorphic computing.
