MATTHEW R. BEGLEY is a professor of mechanical engineering and materials at the University of California, Santa Barbara, having served previously on the faculty at the University of Connecticut (1997-2001) and the University of Virginia (2001-2009). His research focus is on theoretical mechanics and advanced simulations to guide materials development, with an emphasis on multilayered systems, interfaces, and composites. He has more than 100 archival publications, with topics that include thermal barrier coatings, environmental barrier coatings, the mechanical integrity of microelectronics, advanced simulations of virtual tests, bio-inspired composites and adhesives, novel 3D-printing strategies for two-phase materials, acoustic assembly of colloidal particles, the structural integrity of microelectronics, nano-porous gold, and the performance of microfabricated devices for biochemical diagnostics. He has also served as a consultant regarding material behavior and structural performance, for industries, including nuclear energy (Areva), fuel cell energy (FCE), solar power (Sunpower), biomedical implants (legal consulting, 4WEB), and thin films/coatings (Intel, Pratt & Whitney, Raytheon).

BRETT COMPTON is an assistant professor in the Department of Mechanical Engineering at the University of Tennessee, Knoxville. He earned his Ph.D. in 2012 from the University of California, Santa Barbara. Before joining the University of Tennessee, Knoxville, Compton did postdoctoral research at the Wyss Institute for Biologically Inspired Materials at Harvard University, and he was a materials

scientist in additive manufacturing for the Manufacturing Demonstration Facility at Oak Ridge National Laboratory. Currently, his work involves developing new high-performance materials for additive manufacturing (AM) technologies and developing the necessary fundamental understanding of AM processes to enable the application of rigorous engineering principles to AM components. This work requires establishing the link between feedstock processing parameters, deposition parameters, and the mechanical and functional properties of the resulting materials through mechanical testing, numerical simulation, and modeling. Of particular interest for his research are printable fiber-reinforced polymer and ceramic matrix composites and multi-material hybrid structures, which represent a huge area of untapped potential now accessible through AM techniques. Potential areas of application include aerospace, nuclear power, armor, wear materials, and lightweight, highly efficient structures for the transportation sector.

JOSEPH M. DESIMONE is CEO and co-founder of Carbon, Inc. As a professor at the University of North Carolina, Chapel Hill (UNC) for more than 20 years before launching Carbon in 2013, he made scientific breakthroughs in several areas, including green chemistry, medical devices, and nanotechnology, also co-founding several companies based on his research. For 3D printing, he brought together insights from diverse fields to co-invent the core technology that now drives the Carbon Platform. Powered by Digital Light Synthesis^TM (DLS^TM) technology, the Carbon Platform is enabling companies to break free of traditional polymer manufacturing methods to advance product innovation. Carbon has cracked the code on 3D printing at scale and is now a 400+ person global company defining the digital revolution in manufacturing. DeSimone studied chemistry at Ursinus College and went on to earn his Ph.D. at Virginia Tech in 1990, joining the faculty at UNC that same year. He quickly achieved international recognition as a scientist, inventor, and entrepreneur, earning major accolades, including the U.S. Presidential Green Chemistry Challenge Award and the Lemelson-MIT Prize. In 2016 President Obama awarded him the National Medal of Technology and Innovation. At UNC, he built a strong culture in his research group centered on the notion that diversity is a fundamental tenet of innovation. He mentored 80 students through Ph.D. completion, half of whom are women and other members of underrepresented groups in STEM (science, technology, engineering, and mathematics). He credits much of his laboratory’s success to this approach, frequently emphasizing how both human and disciplinary diversity accelerate progress in team problem solving. He now implements this perspective at Carbon and considers it crucial for Carbon’s position as a world-leading digital manufacturing company operating at the intersection of software, hardware, and material science. An author of more than 350 scientific publications and a named inventor on nearly 200 patents, he maintains academic appointments at both UNC and North

Carolina State University. He is a member of the National Academy of Sciences, the National Academy of Medicine, and the National Academy of Engineering.
