Andre Ellis - Research Overview
Isotope geochemistry and Low temperature geochemistry of redox active elements is a major component of my research interests. The field of the so called non-traditional isotopes has exploded in recent years, especially with the relatively newer Multi-collector ICPMS instrumentation becoming common. Along with collaborators Tom Johnson at Illinois and Tom Bullen at the USGS, I had worked on some of the early development of techniques related to measurements of chromium and selenium stable isotopes.
