IMG faculty and students are a major part of the NSF Industry/University Cooperative Research Center (I/UCRC) Planning Meeting for Multi-functional Integrated System Technology (MIST) held Nov. 19-20 at the UF Hilton Conference Center.  Led by Dr. Toshi Nishida (Director) and Dr. David Arnold (Deputy Director) and facilitated by all of the IMG faculty, over 30 representatives from companies and agencies attended the planning meeting.  Several poster presentations were given by IMG students. The MIST Center is a joint effort between UF and UCF with the mission to pioneer the "More than Moore" era by developing materials, processes, and devices that increase the functionality of integrated systems.
