Dr. Jorge Peon obtained his bachelor’s degree in Chemistry from the National Autonomous University of México, and his Ph.D. in Physical Chemistry from The Ohio State University, USA. He also made postdoctoral studies at the California Institute of Technology USA. He joined the Institute of Chemistry of the National University of Mexico in 2003.


Studies of the dynamics of electronically excited states of molecules, including ionization phenomena, internal conversion, energy transfer, electron transfer, proton transfer, and photochemical transformations.


Graduated students: 8 BSc, 7 MSc, and 4 PhD.

Students interested in Dr. Peon's supervision for thesis (graduate and undergraduate), social work, research summer or professional practices are welcomed.


He has been an invited speaker at several international conferences, includingUltra-fast and Ultra-small: New Frontiers in AMO Physics”, “Femtochemistry 10”, and the International Conference on Photochemistry 2011”.
