Dr. Kalina'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 planetary boundary layers. 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 the prediction of tropical cyclone track, intensity, and structure. 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.
