❝
I am interested in understanding how mountains grow and how the sedimentary system responds to tectonic processes and climate. My main field of expertise is in sedimentary geology and low temperature thermochronology (in particular fission track and 40Ar/39Ar). I apply multidisciplinary approaches involving thermochronology, geochronology, basin analysis and sedimentology to constrain the timing and rates of erosion and sedimentation, mechanisms of basin formation and paleodepositional environments. I am involved in projects in the Andes, Pamir, Tibet, Nepal, North America Cordillera and Alps. I teach classes in Historical Geology, Sedimentology and Stratigraphy, Basin Analysis, Field camp, Applications in low-T thermochronology and various graduate level seminars. I like to involve both undergraduate and graduate students in research.Show Less
