Vertebrate paleontology, North American Pliocene and Pleistocene small mammal biostratigraphy and biochronology, osteology, anatomy, and systematics of squamate reptiles and turtles, Impacts of climate change on vertebrate communities
|Daniel O Breecker|
Soil biogeochemistry, calcic soils, stable isotope geochemistry
Dr. Caldwell is a hydrologist and geoscientist specializing in field investigations and numerical modeling associated with near-surface vadose zone hydrology, landscape evolution, and soil moisture/ET. His current research focuses on ecohydrology, soil moisture modeling and monitoring, restoration and characterization of disturbed lands, the characterization and scaling of soils and hydraulic parameters, near-surface geophysics, and parameter optimization and numerical methods.

|Elizabeth J Cassel|
The interactions between tectonics, climate, and erosion; Earth surface processes; tectonic geomorphology; stable isotope geochemistry and its applications to paleo-elevation, -climate, and -hydrology; fluvial and alluvial depositional environments; sediment provenance and drainage evolution through detrital mineral geochronology; sedimentology and stratigraphy; major, trace element, rare earth element, and stable isotope compositions of volcanic glass; Laramide tectonics and drainage system responses.
I am broadly interested in Earth surface system evolution, thus my research focuses on sedimentary geology, geochemistry, and paleontology. My field-based projects utilize integrative methods that include detrital zircon geochronology and provenance, carbonate isotope geochemistry, paleontology and biostratigraphy.
