Designed and conducted studies to obtain the necessary surface and subsurface geological and geophysical data for the planning, design and construction of the foundations for buildings and other structures.  Directed and trained personnel to perform soil mechanics laboratory and field-related duties.  Prepared geologic maps, cross sections and reports.  Conducted numerous investigations to evaluate landslide and earthquake ground-rupture hazard.

EXPERIENCE
RESEARCH
My research interests in Quaternary geology and geomorphology are centered in Death Valley, but I have also participated in studies of coastal dunes and the Sierra Nevada of California. My collaborations over the last 10 years have focused on the late Neogene stratigraphy, Lake Manly history, and geomorphology of Death Valley. In past studies, I and my colleagues have used a variety of geochronologic methods including tephrochronology, paleomagnetics, cosmogenic radionuclides, luminescence, radiocarbon and soil development to support geologic mapping.
