Univeristy of Arizona


I am a PhD candidate in the Past Landscapes Lab at the University of Arizona in the School of Geography and Development and the Laboratory of Tree-Ring Research. My research focuses on high-latitude climate variability, extreme events, and the climatic effects associated with large volcanic eruptions. I use a wide range of data and tools (tree rings, historical observations, climate model simulations, and proxy systems modeling to name a few) and specialize in high-resolution, and multivariate analyses from quantitative wood anatomy.
