Ryan T. Elliott
Principal Member of Technical Staff
Biography
Ryan T. Elliott received the Ph.D. degree in Electrical and Computer Engineering in 2020 from the University of Washington, Seattle, WA, USA, where he studied in the Renewable Energy Analysis Lab (REAL). He is currently a Principal Member of Technical Staff with the Electric Power Systems Research Department at Sandia National Laboratories. In 2017, he earned an R&D 100 Award for his contributions to a real-time damping control system using phasor measurement unit (PMU) feedback. His research interests include renewable energy integration, wide-area measurement systems, and power system dynamics and control.
