Research Interests

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.

Current Research

  • 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


El Niño is a naturally occurring climate pattern associated with warming of the ocean surface temperatures in the central and eastern tropical Pacific Ocean, which can significantly influence weather patterns, ocean conditions, and marine fisheries worldwide. Image: NOAA
