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 composition or in terms of chronology. One of my main specialties is the analysis of meteorites using noble gases (He-Xe) and halogens (Cl, Br, I), and chronology studies (e.g. Ar-Ar, CRE). More recently, I have been working on overall compositional studies of meteorites at micro- and nanometer- scales
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.

Current Research Projects
I am looking for motivated graduate and undergraduate 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 an undergraduate research project, a master’s degree or PhD in my group!
Special Announcement for 2019
Funded Graduate Student Research Assistant (RA) Position in Meteorite Studies
The CCL Group at the University of Alabama Department of Geological Sciences announces the availability of a fully-funded MS or PhD position in the area of chronology studies of achondrite meteorites. The project involves the analysis of selected clasts within meteorites using multiple chronometers to improve the understanding of the impact flux in the inner Solar System.
Qualified applicants should have research experience (preferably in geochemistry) including handling of geological samples, data-handling experience, and a degree in geology, geochemistry, astrophysics or physics.
Interested candidates should email the following items to Dr. Julia Cartwright at email@example.com:
- An up-to-date resume or CV;
- A 500-word (max) research interest statement;
- A 200-word (max) career interest statement;
