Dr. Ruiz is an electrical engineer and economist with over ten years of experience in electric power markets and systems design, analysis and research. He specializes in renewable power integration and the modeling and analysis of transmission systems and wholesale electricity markets.

Dr. Ruiz is also an associate research professor at Boston University, where he served as the principal investigator for the DOE ARPA-E Topology Control Algorithms project. Currently, he is leading the design of gas balancing markets as part of the DOE ARPA-E Gas Electric Coordination project. Dr. Ruiz co-founded NewGrid, Inc., a software start-up developing transmission topology optimization software.

Dr. Ruiz has published journal articles and has presented papers at international conferences on wind integration and uncertainty management, power flow analysis, voltage stability, operating reserve requirements, transmission expansion, transmission topology optimization and unit commitment.

Prior to joining Brattle, Dr. Ruiz was an associate principal at Charles River Associates (CRA) and a Power Systems Engineer at AREVA T&D. He has held research and teaching assistant positions at the University of Illinois and at Universidad Tecnológica Nacional, Argentina. Dr. Ruiz holds a Ph.D. in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign.
