Research/Engineering Interests
   Current Research

Use of remotely sensed data from various airborne, satellite, and handheld sensors to investigate geohazards; environmental geology; lunar field geology; patterns of spatial and temporal land cover change; and urban/peri-urban climate.

Application of visible, near-infrared, and thermal infrared remote sensing to soil development, sediment transport processes, and hillslope geomorphology of semiarid mountain ranges.

Investigation of thermal emission spectroscopy and linear deconvolution techniques for determination of mineralogy in rocks and soils.

   Prior Research

Determination of rheologic properties of ancient lavas and magmas in Chino Valley, Arizona using entrained xenolith distributions and physicochemical properties.

Characterization of the geochemistry and emplacement history of alkaline igneous rocks associated with the final intrusive stages of the White Mountains Batholith in New Hampshire.
