Research Statement:

I am interested in understanding the dynamics of orogenic evolution in mountain belts and continental plateaus (e.g. Alps, Andes, Western US Cordillera and recently the western Pamirs and Tibet) by determining deformation and exhumation within the orogenic belt and sedimentation within the foreland basin. My main field of expertise is in sedimentary geology and low-T thermochronology (40Ar/39Ar and AFT). In recent years my efforts have been concentrated in applying multidisciplinary studies using emerging, together with well established, techniques that enable determination of timing and rats of exhumation, erosion and sedimentation leading to a better understanding of the mechanisms driving mountain building and sedimentary basin development. One particular field of interest is ‘detrital thermochronology’, i.e. the application of low-T-thermochronology to sedimentary rocks and sediments. I also use structural geology and basin analysis in order to unravel the kinematics of sedimentary basin formation through time.

Teaching Statement:

I enjoy teaching both at graduate and undergraduate level and I particularly enjoy advising students through continuous support and scientific discussions. I feel very involved and responsible for the future scientific preparation and the career of my students and I am confident that a solid preparation via core classes and scientific interactions will lead them to be well prepared in their field, confident and ultimately scientifically independent.
