I am a research scientist at NOAA's Earth System Research Laboratories (Physical Sciences Laboratory, PSL) in Boulder, Colorado. I am a member of PSL’s Attribution and Predictability Assessments Team which seeks to understand the physical factors that cause observed regional and seasonal climate trends, and high-impact weather and climate events. We place a special emphasis on understanding the large-scale drivers that influence local and regional extreme events such as floods, droughts, and heat waves.
- Understanding the role of stratospheric processes in predicting ENSO-NAO connections on subseasonal time scale
- Development of a probabilistic approach to multivariate ENSO monitoring
- Understanding the faces of ENSO teleconnections
