Climate, Atmospheric Science & Physical Oceanography

Director, Center for Western Weather and Water Extremes (CW3E)

Research Interests

  • Precipitation – diagnosing key physical processes controlling rain and snow formation and developing new methods for precipitation monitoring and prediction
  • Hydrometeorology – exploring atmospheric and land surface conditions that drive streamflow (from weather to climate scales)
  • Water resources – developing modern tools to aid in balancing water supply and flood control in a changing climate
  • Observations – applying new observing strategies (sensors and networks) to water cycle science and prediction
  • Atmospheric chemistry – exploring the role of aerosols in clouds, precipitation and water supply
