Additional Information:

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 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. 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 to 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.
