My research centers on extratropical cyclones, complex weather systems where processes at the microscale and mesoscale can affect higher length scales, including the entire storm at the synoptic scale. Such an interaction also occurs in the downscaling direction, where synoptic conditions can affect meso- and micro- scales.

Past work includes employing a multi-perspective approach to diagnose the effects that latent heat release has upon extratropical cyclones. Using output from NASA's A-Train constellation of satellites as well as reanalysis data and the Weather Research and Forecasting model  to arrive at a fuller understanding of these scale linkages in a real-world case study.

My current projects aim to define these links better, and involves numerical modeling as a platform to test the sensitivity of idealized extratropical cyclones to changes to environmental characteristics, allowing a fuller picture of how these crucial mid-latitude weather systems might react to a changing climate system.
