I am interested in the study of meteorites to better understand the formation and evolution of our Solar System. My research approach is to use multiple techniques to characterise extra-terrestrial materials either in terms of petrology, composition and chronology. One of my main specialties is the analysis of meteorites using noble gases (He-Xe) and halogens (Cl, Br, I). I also study chronology, using a number of techniques including Ar-Ar, cosmic ray exposure, U-Pb and Pb-Pb. More recently, I have been working on overall compositional studies of meteorites at micro- and nanometer- scales, to include atom probe techniques.
Current research areas include:
- The chronometry planetary regoliths, with an aim to contribute to solving important scientific questions such as: When did planetary differentiation occur in the asteroid belt? When were the major impact events in the inner Solar System, and did all bodies experience the same history? Can we characterise and identify regolithic meteoritic materials? Can secondary processes like weathering be quantitatively constrained?
- Understanding the structures and compositions of undifferentiated meteorites (chondrites) at micro- and nanometer-scales, to help determine when the first solids in the Solar System formed, and to determine what processes led to their formation.
