About

Graduate Research Assistant and M.S. in Atmospheric Science student at the University of Oklahoma, working with Dr. Ben Schenkel and Dr. Thomas Galarneau through the Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO) and the NOAA National Severe Storms Laboratory (NSSL).

My research focuses on developing an improved radar-based hail climatology using machine learning, which aims to enhance the data relied upon by forecasters, emergency managers, insurers, and other decision makers. This work draws on my undergraduate experiences developing radar and environment-based tools for hail size classification.

Broadly, I’m interested in applying machine learning to mesoscale and convective hazards research, with an emphasis on the research to operations (R2O) process by developing trustworthy, interpretable tools that support operational needs.

Undergraduate Research Assistant

Norman, OK

11/2022 - 08/2025
  • Developed a probabilistic ML, radar-based hail size classification algorithm, utilizing C++ and Python.
  • Contributed to the development of a large dataset of storm characteristics via radar analysis, aiding CIWRO and NOAA NSSL researchers in developing an ML algorithm for tornado prediction.
  • Participated in the PERiLS, DELTA, and HAILSTONE research field campaigns with the NOAA X-POL (NOXP) mobile radar team, mobile mesonet probe team, and hail imaging probe team respectively.
  • Supported several NOAA Hazardous Weather Testbed (HWT) experiments as both a participant [Spring Forecasting Experiment (SFE) x2] and assistant [Probabilistic Hazard Information (PHI) Prototype Experiment; Radar Convective Applications (RCA) Experiment], evaluating experimental products and forecasting techniques alongside federal research partners and facilitating the assessment of warning guidance tools for severe convective hazards as one of the only undergraduates involved.
