My research utilizes a wide range of climate observations and climate model output to analyze observed variations and extremes in the earth’s climate system on timescales ranging from sub-seasonal to multidecadal. I am particularly interested in investigating the causal mechanisms, regional manifestations, prediction, and impacts of drought and heat waves. In addition, I undertake diagnostic analyses of both regional and large-scale changes in the future climate based on coupled climate model projections. I am also interested in quantifying the impacts of climate variations and climate change in various sectors of society, including energy, agriculture and water resources. I have a growing interest in exploring relationships between climate extremes and energy use, demand and generation both in terms of the current climate and climate change projections.
