EPS 201 Earth History

        My research interests are broad but all involve aspects of low-temperature geochemistry.  Currently I am entrenched in the fascinating world of isotopes and desert soils.  Some might consider soils as the omega while others the alpha; and others just consider them a covering to be removed to get to the good stuff.  I consider soils to be the most challenging natural laboratory to explore transitional geochemical processes.  Talk about open system!   Please visit PublicationsandAbstractsfor highlights of past and current research.
