The University of California Board of Regents named Paul Alivisatos director of Berkeley Lab on Nov. 19, 2009. Alivisatos has served as interim director since January 21, 2009, replacing former laboratory Director Steve Chu, who was sworn in as U.S. Energy Secretary. Before becoming interim director, Alivisatos was the deputy director of Berkeley Lab, serving as the lab’s chief research officer, overseeing the discretionary research budget, key research initiatives and technology transfer functions. In addition, he assisted the director in developing the overall strategic direction and institutional planning for the laboratory. Alivisatos is a leader of Berkeley Lab’s Helios solar research initiative, where he directs ground-breaking research on artificial photosynthesis and photovoltaic technology through the creation of nano-inspired devices.

From 2005-2007, prior to being named deputy director of Berkeley Lab, Alivisatos was associate laboratory director for physical sciences. From 2002-2008 he was director of the materials sciences division and from 2001-2005 he was director of the Molecular Foundry at Berkeley Lab. Alivisatos has been a member of the faculty at UC Berkeley since 1988. He is currently the Samsung Distinguished Chair in Nanoscience and Nanotechnology and a professor in the departments of materials science and chemistry.

Alivisatos is a scientific founder of Quantum Dot Corp. and Nanosys Inc., and a board member of Solexant Inc. He is the founding editor of Nano Letters, a publication of the American Chemical Society.

Alivisatos has published widely and is the recipient of numerous awards and honors, including the Ernest Orlando Lawrence Award, the Wolf Prize in Chemistry, the Eni Italgas Prize for Energy and Environment, the Rank Prize for Optoelectronics Award, the Wilson Prize, the Coblentz Award for Advances in Molecular Spectroscopy, and the Department of Energy’s (DOE) Awards for Sustained Outstanding Research in Materials Chemistry and Outstanding Scientific Accomplishment in Materials Chemistry. He has held fellowships with the American Association for the Advancement of Science, the American Physical Society, the American Chemical Society and the Alfred P. Sloan Foundation. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences.

Alivisatos attended the University of Chicago and received a Bachelor's degree in Chemistry with Honors in 1981. He continued his graduate studies at the University of California, Berkeley. In 1986, he went to AT&T Bell Labs where he worked as a postdoctoral, and it was at this time that he first became involved in research related to Nanotechnology. In 1988, he joined the faculty of the University of California, Berkeley and became a principal investigator at Berkeley Lab. His research has earned him recognition as a leading authority on colloidal nanocrystal science.

Horst Simon, an internationally recognized expert in computer science and applied mathematics, was named Berkeley Lab's Deputy Director on September 13, 2010. Simon joined the Lab in early 1996 as director of the newly formed National Energy Research Scientific Computing Center (NERSC), and was one of the key architects in establishing NERSC at its new location in Berkeley. Under his leadership NERSC enabled important discoveries for research in fields ranging from global climate modeling to astrophysics. Simon was also the founding director of Berkeley Lab's Computational Research Division, which conducts applied research and development in computer science, computational science, and applied mathematics.

In his prior role as Associate Lab Director for Computing Sciences, Simon helped to establish Berkeley Lab as a world leader in providing supercomputing resources to support research across a wide spectrum of scientific disciplines. He has also served as an adjunct professor in the College of Engineering at the University of California, Berkeley, working to bring the Lab and the campus closer together and developing a designated graduate emphasis in computational science and engineering. In addition, he has worked with project managers from the Department of Energy, the National Institutes of Health, the Department of Defense and other agencies, helping researchers define their project requirements and solve technical challenges.

Simon’s research interests are in the development of sparse matrix algorithms, algorithms for large-scale eigenvalue problems, and domain decomposition algorithms for unstructured domains for parallel processing. His algorithm research efforts were honored with the 1988 and the 2009 Gordon Bell Prize for parallel processing research. He was also member of the NASA team that developed the NAS Parallel Benchmarks, a widely used standard for evaluating the performance of massively parallel systems. He is co-editor of the biannual TOP500 list that tracks the most powerful supercomputers worldwide, as well as related architecture and technology trends.

He holds an undergraduate degree in mathematics from the Technische Universtät, in Berlin, Germany, and a Ph.D. in Mathematics from the University of California at Berkeley.
