nies Do Bad Things, and China’s Futures. He publishes and lectures widely and served as a script consultant on the films “The Minority Report,” “Deep Impact,” “Sneakers,” and “War Games.” Mr. Schwartz received a B.S. in aeronautical engineering and astronautics from Rensselaer Polytechnic Institute.


Nathan Siegel is a senior member of the technical staff at 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 this 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 Tech 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 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 research director for semiconductors at Gartner. 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 for or consulted to Intel, NASA Langley and NASA headquarters, Mars & Co., and IBM Research.
