The Geochemistry/Geochemist Group at DTM has five staff members: Conel Alexander, Rick Carlson, Erik Hauri, Larry Nittler, and Steve Shirey.  With the support of chemistry lab manager, Mary Horan, mass spec lab manager, Tim Mock, and ion probe specialist, Jianhua Wang, research projects involving the staff can range from a short, informal nature to those that are long term. Research collaborations are welcome on almost any professional level: as an intern, a pre-doctoral fellow, a post-doctoral fellow, a visiting scientist, or a Tuve fellow. Most projects are NSF or NASA funded, but with the Carnegie Institution’s high level of ongoing lab support, important scientific questions can be attacked without the proposal lead-time that NSF or NASA funding requires. The most fruitful collaborations are those that align with the interests of the staff and the type of analyses suited to our facilities (see below).

Cosmochemists address the early history of the solar system, the formation and early evolution of meteorites, and the nature of the impact cratering process on Earth. Research in geochemistry combines laboratory and field studies of modern and ancient rocks from diverse geographic areas.
