Biogeography, Dendrochronology, Long-term Climate Change, Land Use, GIS

Over the years my research in climatology has melded Geographic Information Systems and Paleoclimate.  I have worked with tree-ring growth studies in Califormia, Arkansas, Virginia, and Mississippi and I currently have a tree-ring research lab on the coast campus.  My academic interests include biogeography, climate change, natural resource management, field research methods, and GIS. 

Currently I am researching landuse and recovery of the Gulf Coast post-Katrina by helping the Mississippi coastal development authorities develop a regional GIS while working with students gathering related field data.  Related work has included mapping municipal cemetaries impacted by storm surge, identifying and mapping blighted properties as a relic of Hurricane Katrina, and seeking to understand the fluvial morphology and environmental management of Turkey Creek, Gulfport, Mississippi.
