His PhD dissertation at Dalhouse University, in Canada, dealt with quantitative analysis of geomorphic processes in the southern Central Andes. After finishing his PhD, he moved to Reno, Nevada, where he worked on projects aimed to understand the linkages between late Quaternary paleoclimate and the pace of alluvial and hillslope processes in semiarid and alpine areas of the US, Mexico and South America. His expertise includes Quaternary geochronology techniques (cosmogenic isotopes and IRSL/OSL dating).
