Overview
Personal Profile
Rebecca joined NLR as an intern with the Thermal Sciences Group in 2018. She works on algorithms to determine canting error of heliostats. Before coming to NLR she did her dissertation research in dynamical systems in the Department of Applied Mathematics at the University of Colorado , Boulder, investigating mixing of two-dimensional fluids. Her other areas of interest include machine learning and data analytics.
