Nikita Dutta joined the Analytical Microscopy Group at NREL as a director’s postdoctoral fellow in 2021. Her research focuses on applying cryo- and in situ transmission electron microscopy to study structural evolution and degradation in battery and photovoltaic materials during device operation. Prior to joining NREL, she completed her doctorate with Professor Craig Arnold at Princeton University, where she used cryo-electron microscopy in conjunction with other characterization techniques to study structural evolution and structure-property relationships in solution-processed optoelectronic materials. At NREL, she aims to continue investigating such relationships in energy materials and to link them to device performance by advancing novel microscopy methods to characterize dynamic material structures at high-spatial and temporal resolution. She is also involved in NREL’s energy justice work, particularly in developing frameworks to consider energy justice in early-stage research.
