Research Interests and Expertise
Dr. Langston is an ecologist with over 20 years of research and applied experience. Her work focuses on investigating responses of ecosystems to climate change and local disturbances, and developing strategies for promoting ecosystem resilience. She is especially interested in ecosystem turnover, changes in species ranges and distributions, and landscape scale changes in ecosystem functions in response to climate change. Dr. Langston primarily works in coastal and desert systems. She uses a variety of tools, including modeling, field observation and experimentation, and spatial analysis, to address research questions.
Prior to joining DRI, Dr. Langston was a postdoc at the Virginia Institute of Marine Science, where she developed a salt marsh accretion model to predict landscape-level responses of marsh systems in Massachusetts and Georgia to scenarios of sea level rise. She also used field data and remote sensing to compare ecosystem functions in old and newly formed marsh, investigated vegetation turnover in developing ghost forests, and analyzed red cedar responses to press-pulse disturbances (sea level rise and coastal storms) along the mid-Atlantic.
As a PhD student, Dr. Langston studied freshwater forest retreat and poleward mangrove migration along the Gulf Coast of Florida. She also worked with a rural coastal community in Florida to develop sea level rise adaptation strategies and collaborated on research with USGS evaluating the freeze tolerances of mangroves along the southeastern US.
In her applied work, Dr. Langston has managed several grant-supported conservation projects benefitting desert systems threatened by changing land use, wildfire, and recreation activities in the Mojave Desert. She has also worked in environmental consulting in California, where she conducted wetland delineations and CRAM assessments, evaluated potential impacts to natural resources from proposed projects, and prepared technical reports and permit applications in compliance with NEPA/CEQA requirements.
Dr. Langston has a PhD in environmental engineering from the University of Florida, an MS in biology from San Francisco State University, and a BS in ecology from Cal Poly, San Luis Obispo.
