I am interested in the relationships between igneous and metamorphic processes and their tectonic settings, in particular on the continental crust, and within Andean margins. I am especially interested in magmatic rocks of subduction origin, as they form from the surface to the bottom of the crust.
My main current areas of research are the central Andes, the Carpathians, southern Tibet, and the western US.
I run an quad ICP-MS geochemical and TIMS isotopic laboratory facility at Arizona, which includes a clean lab and several mass spectrometers; in it, we measure trace elemental concentrations of rocks and minerals, isotopic ratios and ages of rocks.
I hold courtesy appointments with the University of Bucharest (Romania) and the China University of Geosciences (Wuhan). I spend my summer in these places and want to be a catalyst of scientific exchange between them at Arizona.
As for teaching, I am on the rotation of undergraduate Petrology, Physical Geology and Field Camp, and I also teach Tectonics, Tectonic Petrology, and various seminars for graduate students. I am one of the associate editors of International Geology Review, and serve on a variety of departmental and outside committees.
