Professional Interests

Affiliated with the NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML) Hurricane Research Division (HRD) in Miami, Florida. I work remotely in Boulder, CO, investigating the impact of current and future observing systems, specifically uncrewed aircraft systems (UAS) data, to improve short and long-term weather forecasts of winter storms and tropical cyclones. Some of my most recent work evaluated the impact of Global Hawk UAS dropsonde observations on the prediction of winter storms and tropical cyclones in 2016 flights. Most of my research involves conducting observing system experiments (OSEs) and observing system simulation experiments (OSSEs), in which supplemental data is assimilated into a numerical forecast model. The addition of the data is compared to a simulation without the added observations, thus allowing the evaluation of the data impact for improving prediction.


In my free time, I enjoy volunteering, learning piano, playing tennis, swimming, and hiking.
