Research interests

- Understanding the formation and evolution of planetary bodies within the inner Solar System through chemical and isotopic studies.

- High resolution chronometry based on short- (26Al-26Mg) and long-lived (U-Pb, 147Sm-143Nd, and 176Lu-176Hf) radionuclides to study the dynamics of the solar nebula, and the accretion, impact and differentiation processes and histories of asteroids and terrestrial planets.

- Stable and radiogenic isotope and trace element studies to unravel the bulk composition, differentiation of major reservoirs, and impact histories of terrestrial planets.

- Development of new geochemical approaches and cutting edge laboratory techniques.

---

Analytical and instrumentation experience

- Mass spectrometry: expertise in U-Pb, Al-Mg, Lu-Hf, and Sm-Nd radiogenic systems and isotope analyses by Multi-Collector ICP-MS (VG Elemental Plasma 54 and Thermo Finnigan Neptune). Experience with Rb, Sr, Sm, Nd, U and Pb isotope analyses by TIMS (Fisons VG Sector 54-30 and 54E), and Laser Excimer coupled with Neptune MC-ICPMS. Trace element analyses by quadripole ICP-MS (VG Elemental Plasmaquad 2+ and Thermo-Optek X7 CTT).

- Analytical developments in clean lab for ultra-low blank purification procedures for Pb-Pb, Al-Mg, Lu-Hf, and Sm-Nd dating of meteorites. Rb-Sr, Sm-Nd, Lu-Hf, and U-Pb separation techniques for terrestrial igneous rock and mineral isotope studies.

- Electron microprobe and scanning electron microscopes for petrographic studies.

- Mineral and inclusion separation techniques for meteorites and terrestrial igneous rocks.
