Research Emphases

Applied Climatology, Gydro-Climatic Variability and Synoptic Climatology

Specific Research Endeavors

  • Examining climate variability and extremes and their impacts in the United States.
  • Assessing the use of climate information by weather-sensitive decision makers.
  • Developing climate-related decision support tools for users in climate-sensitive areas such as utilities, agribusiness, recreation, transportation and water resources.
  • The one common theme that integrates my research, teaching and service efforts at NIU involves demonstrating value in climate information to weather-sensitive decision makers.
