Research Interests

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 noble gases, halogens and chronometry of extra-terrestrial materials as tools to help us better understand the timescales and processes involved in planetary body formation and evolution. My two current research areas include:

  1. The chronometry of ancient materials and 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?
  2. The structures and compositions of ancient materials from undifferentiated meteorites, to help determine when the first solids in the Solar System formed, and to determine what processes led to their formation.

Keywords: Planetary Science, Cosmochemistry, Noble Gases, Halogens, Meteorites, Mars, Chondrites, The Asteroid Belt, Chronology.

Current Research Projects

I am new faculty at UA (Jan 2017), and I am looking for motivated students with an interest in planetary science and cosmochemistry to pursue topics in noble gases and chronology, as well as compositional studies of meteorites. Do contact me if you’re interested in pursuing a masters or PhD program in my group!
