Modeling and Data Assimilation




(303) 497-6551


I am a Research Scientist II affiliated with CIRES, Univ. of Colorado working in the Atmosphere-Ocean Process team of NOAA's ESRL/PSD. I use sophisticated numerical models together with observations to improve understanding and prediction of convection and its interactions with dynamics so that society can better respond to changes in weather and climate.
