Current position: Post-doc, University of Cape Town, South Africa. Terrestrial Ecosystem Ecology Research Laboratory: Website
Current research: My research focuses on studying the quantity and effects of anthropogenic nitrogen deposition into the natural ecosystems. Cape Town is home to one of the most diverse plant regions in the world, the Cape Floristic Region with over 9000 species of which 68% are endemic. We are trying to understand how the adjacent city is influencing plant diversity and ecosystem health. We are measuring nitrate and ammonium in rainfall and cloud condensate at 30 sites in and around the Cape Town Metropolitan Area in South Africa.
Study sites: Cape Town Metropolitan Area in South Africa

Current research: I am interested in the processes affecting molecular evolution in natural populations, and the genetic architecture and evolution of barriers to gene flow between species. My research is hypothesis driven and combines theoretical analysis, the development of statistical methods, manipulative experiments, and model-based analysis of high-throughput DNA sequence data. Although I study several biological systems, much of my empirical research is on butterflies in the genus Lycaeides. These butterflies are host plant specialist and are characterized by recent population divergence and geographically widespread hybridization. Currently, I am working with these butterflies to (i) test hypotheses regarding the relative roles of stochastic and deterministic processes in evolution, (ii) quantify the scale and determine possible causes of heterogeneity in genome divergence and introgression during speciation, and (iii) identify regions of the genome associated with morphological, behavioral, and fitness variation in natural populations.
Current research sites: Mountain ranges in western North America, including the Rocky Mountains, the Sierra Nevada, the Warner Mountains, and the White Mountains. Several of my fields sites are in Grand Teton and Yellowstone National Parks.

Current research: I work as part of a larger, collaborative project examining the capacity of forest management strategies to impart resilience and resistance of ecological processes to changing climate. I participate in research that assesses the impacts of long-term forest management regimes on forest-level responses to variations in weather and disturbance in northern Lake States and New England experimental forests.

Current position: Assistant Professor, University of Wisconsin-Madison. Department of Forest and Wildlife Ecology: Website
Current research: I am interested in the response of mammal populations and communities to human disturbance, particularly as it relates to developing effective conservation strategies. I work in diverse ecosystems and employ a variety of techniques, from traditional ones like live capture, radiotelemetry and observation to more advanced ones involving molecular markers, stable isotopes and mathematical modeling to answer questions relating to mammalian ecology and conservation.
Study sites: Islands off of the Pacific Northwest (martens), Costa Rica (sloths), northern Wisconsin (porcupines).
