Dr. Gonzàlez received his Ph.D in Theoretical Chemistry at Wayne State University, in 1990.  He then moved in 1991 to Pittsburgh where he worked as a postdoctoral associate in Carnegie Mellon University under the supervision of Prof. John A. Pople, Nobel Laureate in Chemistry 1998.  He joined the Chemical Sciences and Technology Laboratory at the National Institute of Standards and Technology in 1997 as a Research Chemist, after spending 5 years as a Research Specialist at the Pittsburgh Supercomputing Center, Carnegie Mellon University.  Dr. Gonzàlez has extensive experience in the development and implementation of modern ab initio quantum chemical methodologies and their application to a wide variety of chemical problems.  His work leading to the development of an efficient methodology to compute minimum energy reaction paths within the Intrinsic Reaction Coordinate formalism has been widely cited in the open literature (over 2500 citations, according to the Citation Index).  Recently, Dr. Gonzàlez has founded NIST's Center for Theoretical and Computational Nanosciences, which he directs.  The Center's mission is essentially:  (1) To develop, implement and validate efficient and reliable theoretical methodologies and computational infrastructure required for understanding chemistry, physics, and biology at the nano-scale; (2) Serve as a center for collaboration with scientists in industry, academia and national labs to efficiently apply theory and simulation in the field of nanotechnology; and (3) Help industry identify and utilize effective computational solutions to problems limiting realization of the promise of nanotechnology.  Dr. Gonzàlez has published over 80 papers in the area of quantum chemistry, and is one of the co-authors of the Gaussian suite of programs, the most popular ab initio electronic structure package currently available.  Dr. Gonzàlez's research interests focus in the development and implementation of reliable and efficient quantum chemistry methodologies in the study of chemical reactivity, long-range interactions in molecules and solids, and nanotechnology.
