I'm from Milwaukee County, Wisconsin, where I became fascinated with all sorts of weather. A compelling interest in severe storms drew me to the University of Oklahoma, where I graduated with a bachelor's degree in meteorology and spent time on the club soccer and frisbee teams, doing research, and storm chasing, both for fun and as part of field work. My two primary mentors during my time at OU were James Ruppert and John Peters, both CSU grads, and I concentrated my research on the dynamics of supercell thunderstorms and tropical cyclones. Here at CSU, I'm exploring the dynamics of tropical convection through a theoretical and modeling perspective, and remain invested in understanding high-impact extreme weather across scales and geographies. Research is one of my biggest passions, in addition to running, biking, community-building, music, and working towards a better understanding of America and the world at large.
