Matthew Reynolds' research at NREL is focused on applying uncertainty quantification techniques to optimal power flow problems, especially within the context of increased penetration of renewables. 

Prior to joining NREL in 2017, he worked as a postdoc at the University of Colorado's departments of applied mathematics and aerospace engineering sciences. During this time, he worked on a variety of problems in topics such as residual atmosphere modeling, uncertainty quantification (UQ), and food science.
