My academic background is in ecology and environmental science, with a specific focus on quantitative plant ecology. I am largely driven by research that uses robust quantitative methods to address ecological questions with applied conservation outcomes. My efforts at building quantitative skills stem from a growing recognition of the utility of statistical and analytical tools for solving multi-dimensional and otherwise complex environmental problems. For my master’s research, I combined my own field data collection with long-term demographic models to develop models that assess sustainability of leaf harvest from a palm species in Mexico. For my Ph.D. research, I am integrating several existing datasets with statistical models that seek to understand recent and future ecological impacts of climate change on plant species and communities in Wisconsin. Additionally, I have a professional background in collaborative natural resource management and conservation planning. Collectively, these experiences have shaped my expectations for how we can best manage and conserve our natural resources and the environment at large.
