Honorary Postdoctoral Associate
My overall research interests include modeling the effect of human alterations on natural habitats, species distributions, and organism dispersal. The goals for my research include providing knowledge to improve management and conservation of natural habitats and biodiversity. While my research approach has included a range of techniques from field-based studies to population genetics, I have extensive GIS and statistical modeling experience as it relates to species distributions and dispersal in ecosystems altered by urbanization and agriculture.
My recent post-doctoral experience included evaluating the effects of land use and climate on wetland hydrology and productivity in the Prairie Pothole Region of North Dakota. Wetland drainage in the region has led to higher and more stable water levels in these highly productive and important wetlands, leading to lower productivity and less habitat for waterfowl and shorebirds. My PhD work involved modeling the distribution and loss of cypress (Taxodium distichum) wetlands in central Florida and to determine how urbanization has affected the spatial pattern, recruitment, and dispersal of cypress in isolated wetlands. Despite the current commonality of cypress wetlands in the region, there has been a considerable loss of cypress wetlands due to urbanization and the trees virtually cease recruitment at 20 years post-urbanization.
My current postdoctoral research will include a climate change vulnerability assessment of grassland birds. This will include using climate projections and land-use change models to develop demographically-informed species distribution models in order to estimate species-specific sensitivities and exposures to future climate change. This project will also involve building management scenarios to assist managers in evaluating the efficacy of current grassland bird management and conservation planning in the future. We will produce spatially explicit projections of population dynamics to identify regions that might become more or less suitable for grassland birds in the future.
