Short Biography

Professor Garcia-Garibay received his B.S. degree in 1985 at the Universidad Michoacan in Mexico, and his PhD in 1988 from the University of British Columbia, in Vancouver. After working as a postdoctoral fellow at the the University of British Columbia and at Columbia University, he joined the faculty at UCLA in 1992.


Prof. Garcia-Garibay has been a Faculty member in the Department of Chemistry and Biochemistry since 1992. He came to UCLA after doing Postdoctoral research at Columbia University, which followed his PhD studies at the University of British Columbia, in Canada. The earlier portions of Dr. Garcia-Garibay's education were completed in his native, Mexico, at the Universidad Michoacana, where he did research on natural product isolation and characterization. Dr. Garcia-Garibay was promoted to full professor in the year 2000 and he has served as Vice Chair for Education in the Department of Chemistry and Biochemistry since 2005 and as chair since July 2012. Dr. Garcia-Garibay is a member of the editorial board of the Journal of the American Chemical Society and the Journal of Organic Chemistry. He has been a member of the CNSI since 2005. His current research efforts are aimed at the development of artificial molecular machinery in highly organized crystalline media, and to the development of green chemistry by taking advantage of organic reactions in molecular nanocrystals.

Research Interest

The Garcia-Garibay research group is dedicated to the study of solids and crystalline materials spanning a wide range of properties and length scales. There are four main research thrusts in the group (I) The design of reactions in crystals for both synthetic and materials applications; (II) The design of solid state materials with functions that rely on controlled mechanical changes at the molecular level, including electrooptics, ferroelectrics, etc. (III) The use of nanoparticles to control photochemical processes, and (IV) the study of structure-reactivity correlations based on solid state reaction rates and X-Ray structural analyses, including the control of reactive intermediates and a better understanding of quantum mechanical tunneling.
