Matt is the lead for the Storm Process, Analysis, Research, and Knowledge (SPARK) team in the Analysis and Understanding Branch (AUB). His research generally focuses on storm-scale processes, environments, and predictability using various techniques, including observational analysis, numerical modeling, and theory. This collaborative work features active relationships with CIWRO, SPC, and many other local and external institutions around the world. He is also an Affiliate Associate Professor in the School of Meteorology and enjoys advising graduate and undergraduate students and guest lecturing convection-related courses. Prior to joining NSSL in 2024, Matt was a Techniques Development Meteorologist at SPC (2022–2024) and postdoc/research scientist at CIWRO (2020–2022).
