Message:

I participated in the 28th International Chemistry Olympiad (honorable mention in Organic Chemistry) in Moscow, Russia and in the Iberoamerican Chemistry Olympiad (Gold Medal) in Cocoyoc, Mexico. I graduated with a PhD degree in May of 2005 under the supervision of Robert H. Grubbs and William A. Goddard. I enjoy fast cars (600HP 2.7TT Audi S4), faster bikes (GSXR 750), and traveling to remote places. I like to listen to Rush, Soda Stereo, Enanitos Verdes, die Arzte, Zemfira, and Camaron de la Isla.
