Bio

Research

My research interests primarily focus on improved understanding and prediction of small-scale atmospheric phenomena, especially thunderstorms and their rainfall. In addition, my research focuses on thunderstorm morphological evolution. I am also researching ways to better predict winds for wind energy purposes. Finally, my interest in severe storms includes using machine-learning techniques to improve the storm reports database for estimated severe wind speeds, and exploring climate change impacts on severe weather and flooding.
