Nathan Siegel is a senior member of the technical staff at the Sandia National Laboratories. He received a B.S. in mechanical engineering in 1998 from the California State and Polytechnic Institute at San Luis Obispo. He attended San Diego State University from 1998 until 2000, graduating with an M.S. in mechanical engineering. During that time he was employed at General Atomics in La Jolla and worked in the field of inertial confinement fusion energy, the subject of his master’s thesis. He attended Virginia Polytechic Institute and State Unviersity from 2000 until 2004, when he graduated with a Ph.D. in mechanical engineering. Dr. Siegel’s research at Virginia Tech focused on the development and validation of advanced computational models of proton exchange membrane (PEM) fuel cells. He has been employed at the Sandia National Laboratories since graduating from Virginia Tech. His research activities focus on solar interfaces for high-temperature hydrogen-producing thermochemical (TC) cycles and on the experimental validation of novel TC cycles. He has also recently been involved in PEM fuel cell research using neutron radiography to study two-phase flow within an operating fuel cell.

Alfonso Velosa III graduated from Columbia University with a B.S. in materials science engineering, from Rensselaer Polytechnic Institute with an M.S. in materials science engineering, and from Thunderbird, the Garvin School of International Management, with an M.I.M. in international management. Mr. Velosa is currently the research director for semiconductors at Gartner, Inc. In this position, he focuses on semiconductor supply chain research, with a particular focus on global manufacturing and the semiconductor consumption trends of electronic equipment manufacturers. Mr. Velosa previously worked or consulted for Intel, NASA Langley and NASA Headquarters, Mars & Company, and IBM Research.

Norman D. Winarsky is the vice president of ventures, licensing, and strategic programs at SRI International. He leads all SRI venture and license development, the SRI Commercialization Board, and nVention, SRI’s partnership with the venture capital community that develops early-stage investment opportunities. Dr. Winarsky works with SRI’s business units to identify and develop the company’s highest-value commercial market opportunities from initial concept through commercialization as a license or venture. He has helped found more than 20 ventures, published more than 50 papers, holds two patents and has one pending, and has given hundreds of invited talks, lectures, and presentations throughout the world. He is a founder of the National Information Display Laboratory (NIDL)—a center of excellence for the government in information processing and display technologies. The NIDL is known for establishing a new model for government-industry technology development and commercialization. The program grew to become the National Technology Alliance, run by the National Geospatial-Intelligence Agency and hosted at Sarnoff and SRI International. Dr. Winarsky has served on numerous boards and is currently chairing the SRI Commercialization Board and the SRI nVenture Board, and is serving as a board member of Siri, a spinoff of SRI. In addition, he volunteers as chair of the University of Chicago Visiting Committee for the Physical Sciences Division. He joined SRI in 2001 after more than 20 years with Sarnoff Laboratory, formerly the central research laboratory for the RCA Corporation. Dr. Winarsky and his team received an Emmy Award in 2000 from the National Academy of Television Arts and Sciences for outstanding achievement in the technological advancement of high-definition television (HDTV). While at RCA, Dr. Winarsky was awarded RCA’s highest honor, the Sarnoff Award for “development of the physical understanding and computer software for simulating electron trajectories in picture tube systems.” He holds a Ph.D. in mathematics from the University of Chicago.
