Evan's work focuses on improving numerical weather prediction models by transitioning innovations from the research community into operational systems and through his own applied research on microphysics and the planetary boundary layer. He collaborates with model developers across government labs, academia, and private industry to test and evaluate potential forecast improvements in the Hurricane Weather Research and Forecast (HWRF) system, one of NOAA's operational models for tropical cyclone prediction. He also studies the performance of physics suites in the Unified Forecast System (UFS), focusing on their representation of convective weather. He equally enjoys scientific investigation of applied research questions and software engineering work that focuses on code management and developing workflows for operational modeling systems.
