About Daniel J. TrudnowskiDenis OsipovFelipe Wilches-BernalGraham RogersJoe H. ChowRyan T. Elliott

Graham Rogers graduated from Southampton University Hampshire UK in 1961. He had a varied career in engineering practice and teaching. In the United Kingdom he was a consultant mathematician with Associated Electrical Industries (AEI) Rugby and taught in the Electrical Engineering Department of Southampton University. He emigrated to Canada in 1978 to work in the System Planning Division of Ontario Hydro where he was Senior Engineer Specialist Control. In 1993 he retired from Ontario Hydro and formed Cherry Tree Scientific Software through which he performed consulting in power system dynamics and control and developed computer programs for power system analysis. He was an Associate Editor of IEEE Transactions on Control Technology and was on several IEEE Power Engineering Society committees. He was also an adjunct associate professor at the University of Toronto. He published 40 papers on various aspects of power system analysis and control.   Ryan T. Elliott Ph.D. received the M.S. and Ph.D. degrees in electrical engineering from the University of Washington Seattle in 2012 and 2020 respectively. From 2012 to 2015 he was a Research Scientist with the Electric Power Systems Research Department at Sandia National Laboratories in Albuquerque NM. In 2015 he returned to the University of Washington to pursue a Ph.D. working as a Research Assistant in the Renewable Energy Analysis Laboratory from 2015 to 2020. In 2020 he rejoined Sandia where he is currently a Principal Member of Technical Staff. Dr. Elliott led the development of the WECC model validation guideline for central station photovoltaic power plants in 2015. He also received an R&D 100 Award for his contributions to a real-time damping control system using PMU feedback in 2017.   Daniel J. Trudnowksi Ph.D. received the M.S. and Ph.D. degrees in electrical engineering from Montana State University Bozeman in 1988 and 1991 respectively. From 1991 through 1995 he was with Battelle at the Pacific Northwest National Laboratory where he was a Research Engineer. In 1995 he joined Montana Technological University in Butte where he is currently a Professor of Electrical Engineering. Over the past 30 years his research activities have primarily focused on problems related to power system dynamics and controls. Dr. Trudnowski is a Fellow of the IEEE and is a registered professional engineer in the state of Montana.   Felipe Wilches-Bernal Ph.D. received an M.S. degree in control systems and signal processing from Université Paris-Sud XI Orsay France and a Ph.D. in electrical engineering from Rensselaer Polytechnic Institute. He currently works as a Software Engineer at Google in Boulder CO. From 2015 to 2022 he worked at the Electric Power Systems Research Department at Sandia National Laboratories in Albuquerque NM as a Senior and then Principal Member of Technical Staff. During his work at Sandia he served as a key technical contributor and a PI/Co-PI of multiple projects in the power systems integration area. Dr. Wilches-Bernal's research interests include power system stability and control renewable energy and smart grid technologies and signal processing control techniques and machine learning applied to power systems. He was a key contributor to the team that received an R&D 100 Award in 2017 for developing a control system for active damping of inter-area oscillations. Denis Osipov Ph.D. received the B.S. and M.S. degrees in electrical engineering from the Donetsk National Technical University Donetsk Ukraine in 2004 and 2005 respectively. He received his Ph.D. degree in electrical engineering from University of Tennessee Knoxville TN USA in 2018. From 2019 through 2023 he was a research scientist at the Department of Electrical Computer and Systems Engineering in Rensselaer Polytechnic Institute Troy NY USA when he lead the RPI team to win 2021 IEEE-NASPI Oscillation Source Location Contest. Since 2023 he has been Manager Reliability Planning at the Department of System Planning and Analysis in New York Power Authority Albany NY USA.   Joe H. Chow Ph.D. is Institute Professor Emeritus in Electrical Computer and Systems Engineering at Rensselaer Polytechnic Institute. He received his B.S. degrees in Electrical Engineering and Mathematics from the University of Minnesota Minneapolis in 1974 and his M.S. and Ph.D. degrees from the University of Illinois Urbana-Champaign in 1975 and 1977. He worked in the power systems business at General Electric Company in 1978 and joined Rensselaer in 1987. He is a Life Fellow of the IEEE and a member of the U.S. National Academy of Engineering. He is a past recipient of the Donald Eckman Award from the American Automatic Control Council the Control Systems Technology Award from the IEEE Control Systems Society the Charles Concordia Power Systems Engineering Award and the Outstanding Power Engineering Educator Award from the IEEE Power and Energy Systems Society and the Herman Halperin Electric Transmission and Distribution Award from IEEE.
