My research interests are primarily in paleoclimate studies and surficial processes in arid environments and using the modern analog to interpret the fossil record.  I employ several methods to address research questions in these areas, including mapping, 14C dating, and stable isotopic techniques (13C, 18O, 34S, 87Sr/86Sr).  I am currently working in northern Chile, Jordan and North America.

Possible thesis/dissertation topics

  • Soils and geomorphology of the Atacama Desert, Chile
  • Climate change and water resources in Jordan

Current/recent student research projects

  • Nasser AlQattan (M.S. 2014) Interpretation of oxygen isotopic values (18O) of North American Land Snails.
  • Gentry Catlett (M.S. 2014 ) Pluvial deposits in Mudawwara, Jordan and their implication for Mediterranean and Monsoonal precipitation in the Levant
  • Sophie Lehmann (M.S. 2013) Climate change and water resources in southern Jordan
  • Terry Workman (M.S. 2012) Climate and culture change in Jordan
  • Craig Tully (M.S. 2010) Holocene mega-droughts in the Central Atacama Desert, Chile
  • Emily Winer (M.S. 2010) Interpretation and climatic significance of late Quaternary valley-fill deposits in Wadi Hasa, Jordan
