Biography
My interests lie in untangling the roles
accretionary and differentiation processes play the early history and evolution
of terrestrial bodies. I address questions about the nature and timing of such processes via high precision isotopic analyses using TIMS (thermal
ionization mass spectrometry) and MC-ICP-MS (multi-collector
inductively-coupled-plasma mass spectrometry), in conjunction with ion-exchange chromatography in a metal-free
clean lab.
