[gravatar email=”wells@pcka.com” class=”alignleft” size=”96″ default=”https://pcka.com/wp-content/uploads/2010/08/gravatar.jpg”]J. R. Wells received the BSEE, MSEE, and PhD from the University of Illinois at Urbana-Champaign in 2000, 2003, and 2005, respectively. He is currently a Director of Engineering Services at PCKA. In this position, he serves as principal investigator and technical lead of numerous research and development efforts including simulation software development efforts as well as modeling, simulation, analysis, and design of More Electric Aircraft (MEA) power and distribution systems. In this latter role, he has developed several design changes that have markedly improved the overall performance of the systems. His research interests include modeling, simulation, and control of electric machinery and power electronics and he has authored or co-authored over 20 technical papers.
