Experience: 

Scientist, Met Office Hadley Centre, UK, 2012 to 2015
Postdoctoral Researcher, Oxford University, UK, 2010 to 2012
NASA Summer Internship, NASA GISS, New York, 2006 to 2007

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.
