  • My research activity is based on the use of 40Ar-39Ar dating method to study times and rates of geological processes.
  • Research topics dealt with over the years can be summarized in three main lines: chronological reconstruction of Italian Plio-Pleistocenic magmatism, stratigraphic applications, dating of glasses of various origins.
  • I took part to CNR, GNV, PNRA, MIUR research programs. Currently I am in charge of the IGG Unit of the Ritmare Flagship Project [SP4 (Deep Sea)-WP1], and I am part of the IGG unit in the H2020 project Descramble.
