Research Interests: 

The main focus of my work is producing and communicating physically consistent and spatially coherent information on climate change and associated uncertainties for impacts assessment. In particular, I am interested in developing methods to characterize and quantify uncertainties in model projections by using observations and by diagnosing model imperfections. At the NACS, I am working on understanding observed and projected climatic changes in the northeast US relevant for hydrological and ecological impacts.
