Currently, I work in NOAA/GSL's Evaluation and Decision Support Division. My current research is developing impact-based verification tools for operational agencies and integrating weather observations and model forecasts to analyze the weather impact on air traffic.
I started my career as a supporting scientist on ensemble forecasting research activities at NOAA/PSL. In my previous job at NOAA/GSL, I worked in the Verification and Assessment Branch. During that time, my primary work was to develop a web-based verification system to evaluate model performance, and support model developments by setting up real-time and retro runs.
