Matei "Matt" Georgescu is a Post-doctoral Scholar in the Center on Food Security and the Environment. His general research focuses on the use of mesoscale numerical modeling to study the interaction(s) between the land and overlying atmosphere.  Human alteration of the earth's surface has changed (and continues to change) the manner in which solar radiation is absorbed by the surface and in turn modifies the fluxes of energy and water back into the atmosphere, with significant implications for weather and climate.

Specifically, he is interested in the regional climatic impact of changing landscapes, due to, for example, altered agricultural practices or urbanization. At Stanford, his main goal will be to quantify how local and regional climate responds to landscape change resulting from increased biofuel production.

Dr. Georgescu completed his Ph.D. at Rutgers University in May, 2008. His current work at Stanford is a direct extension of his work at Rutgers, where he investigated, using a numerical modeling approach, the climatic effect of one of the most rapidly urbanizing areas in the United States - the Greater Phoenix region. A recipient of a NASA Earth System Science Fellowship, his work showed the significant impact of anthropogenic landscape modification, in a semi-arid region, on regional climate.

Tom is Co-Principal Investigator for the Nuclear Threat Initiative (NTI) Developing Spent Fuel Strategies (DSFS) project coordinating international cooperation on issues at the back end of the nuclear fuel cycle with emphasis on spent fuel management and disposal in Pacific Rim countries. Participants include senior nuclear officials from Japan, Korea, China, Taiwan, Canada, and the United States.

Tom advises national nuclear waste programs on facility siting, communications, stakeholder engagement, and public trust and confidence. He has worked with the Canadian Nuclear Waste Management Organization (NWMO) for 15 years.

Tom was recently named as the Chair of the recently formed Experts Team to support Southern California Edison  at the San Onofre Nuclear Generating Station.

Previously Tom was a Consulting Professor at CISAC, lead advisor to the Blue Ribbon Commission on America’s Nuclear Future, Member of the National Academy of Sciences Nuclear and Radiation Studies Board, Director of Planning at Lawrence Livermore National Laboratory, and long time senior executive at the Department of Energy where he led the siting of Yucca Mountain as the nation’s candidate site for a geologic repository.

He has degrees in Engineering, Applied Physics, and Chemical Engineering from Harvard University and the University of Pennsylvania.

Jan Stupl is an affiliate and a former postdoctoral fellow at CISAC.  He is currently a Research Scientist with SGT, a government contractor, and works in the Mission Design Division at NASA Ames Research Center (Mountain View, CA). In the Mission Design Division, Jan conducts research on novel methods for laser communication and space debris mitigation and supports concept development for space missions.

Before his current position, Jan was a postdoctoral fellow at the Center for International Security and Cooperation (CISAC) at Stanford University until 2011, investigating technical and policy implications of high power lasers for missile defense and as anti-satellite weapons (ASAT), as well as the proliferation of ballistic missiles. The research on laser ASATs focuses on damage mechanisms, the potential sources and countries of origin of laser ASATs and ways to curb their international proliferation. Before coming to CISAC, Jan was a Research Fellow at the Institute of Peace Research and Security Policy (IFSH) at the University of Hamburg, Germany. His PhD dissertation was a physics-based analysis of future of High Energy Lasers and their application for missile defense and focused on the Airborne Laser missile defense system. This work was jointly supervised by the IFSH, the Institute of Laser and System Technologies at Hamburg University of Technology and the physics department of Hamburg University, where he earned his PhD in 2008. His interest in security policy and international politics was fuelled by an internship at the United Nations in New York in 2003.
