I am currently a Postdoctoral Associate in Carnegie's Department of Terrestrial Magnetism working with Larry Nittler and Conel Alexander. My research concerns the study of organic matter and presolar grains, and their petrographic context in primitive meteorites. I am most interested in carbonaceous chondrites and what their organic and presolar material can tell us about meteorite formation in the early Solar System and subsequent parent body alteration.

As an undergraduate I studied Geological Sciences at the University of Durham in the north of England. I received my PhD in Cosmochemistry from the UK’s Open University in 2009, and then completed a two year Postdoctoral position at the University of Arizona followed by a year at the University of Hawai’i at Manoa. My analytical specialties include SIMS (Secondary Ionization Mass Spectrometry), EMPA (Electron Microprobe Analysis), Raman spectroscopy, and Scanning Transmission X-ray Microscopy (STXM).
