Sergio Ulloa is a condensed matter theorist with recent research interests in correlated electron systems in low-dimensions. He was born and raised in Mexico City, and completed his BS studies at the National University of Mexico (UNAM) in 1979. After a PhD at the State University of New York at Buffalo in 1984, he held a postdoctoral position at Simon Fraser University until 1986, when he joined the faculty at Ohio University; he is now Professor of Physics. He teaches at all levels (from physics for poets to advanced graduate courses), and enjoys daily interactions with the broadly international faculty and graduate student groups at Ohio. He has been Director of the Condensed Matter and Surface Sciences Program and founding member of the Nanoscale and Quantum Phenomena Institute, strongly interdisciplinary research groups on campus. Ulloa's APS experience includes being member and chair of the Committee on Minorities, and Member-at-Large of the FIP, as well as manager of FIP's journal exchange program. He served as President of the National Society of Hispanic Physicists (NSHP) 2006-2007. Ulloa greatly values and thoroughly enjoys the international aspects of physics. He has spent numerous research and sabbatical leaves abroad, which include the Max Planck Institute in Stuttgart and the University of Munich (LMU) in Germany; ETH in Zürich, Switzerland; PUC-Rio, Brazil; Universidad Nacional de Bogotá, Colombia, as well as IFUNAM, CCMC, and IFUAP in Mexico. Ulloa maintains collaborations in Europe, Asia and Latin America, including groups in Argentina, Brazil, Chile, and Mexico. He has organized (or co-organized) different workshops and conferences in condensed matter physics in Latin America, including PASI schools in Costa Rica and Mexico. Ulloa was fellow of the Alexander von Humboldt Foundation in 1994, and was elected Corresponding Member of the Mexican Academy of Sciences in 2005, and APS Fellow in 2007.
The international character of physics is ever more evident in its daily practice. Over the years, FIP has implemented several successful programs and activities to foster awareness of international scientific issues and to enhance cooperation among colleagues the world over. Collaborations reach across countries and continents as Internet communication continues to make those interactions better and more efficient. However, the use of many of these communication advances is not as prevalent, partly due to the lack of diffusion among us all of their advantages and potential. Although various agencies have placed emphasis in the use of these communication tools, the FIP could contribute to this effort by organizing educational projects through its website and newsletters that inform and encourage its members to take advantage of the new technology. This would be particularly useful in the case of researchers in developing countries, where travel budgets are restricted if not prohibitive. It would also be important to continue exploring and welcoming new ideas to further foster international cooperation. As I have personally benefitted a great deal from international collaborations and enjoyed tremendously the synergy they provide, I believe it is important to continue the FIP tradition of furthering international physics interactions in the US, as well as with and among our near and distant neighbors. I would welcome the opportunity to make a contribution for future generations of internationally aware researchers.
