Dr. Dubois was recently appointed a permanent research staff member in the advanced organic materials group as the result of his internal and international scientific recognition: he is currently the author of more than 20 publications, book chapters and patents.

Dr. Géraud Dubois is a native of Sète, a French harbor located on the Mediterranean shore. He pursued his undergraduate and graduate studies at the University of Montpellier II, completing his B.Sc. in organic chemistry in 1994 and M.Sc. in heterochemistry, polymers and catalysis in 1995, both with distinction. In 1999, he obtained his Ph.D. degree summa cum laude from the same University under the supervision of Professor Robert Corriu for work on the synthesis and study of organic-inorganic hybrid materials and their application in dioxygen binding.

From 1999 to 2000, Dr. Dubois was a postdoctoral fellow in the group of Professor Roger Guilard at the University of Burgundy, where he discovered new carbon monoxide captors based on molecular metal complexes. In 2000, Dr. Dubois moved to the United States to pursue a postdoctoral work in the group of Professor Daniel Stack at Stanford University, where he developed bio-inspired catalysts for the selective epoxidation of terminal alkenes.

In 2002, Dr. Dubois joined the IBM Research Division at their Almaden Research Center in California and became the project leader for the development and implementation of new spin-on, low-k materials for 45 nm node technology and beyond. Dr. Dubois research interests focus on the synthesis of porous silicates thin-films with improved mechanical properties as well as the photo-activity of silicon containing polymers for application in nano-imprinting and photo-patterning technologies.
