Professional InterestsI am a Post-Doctoral Associate at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS), affiliated with the Hurricane Research Division (HRD), working remotely from Albany, NY. My research involves conducting Observing System Experiments (OSEs) in order to quantify and assess the value of different instruments on TC prediction.
