Current Research: My research focuses on global climate change in high latitudes resulting from local and tropical influences and is being studied using climate models and atmospheric reanalyses. Furthermore, I am involved in the Arctic System Reanalysis project that concentrates on the behavior of the coupled atmosphere-land-ocean-sea ice system of the greater Arctic which has been re-constructed since 2000 to describe and understand that rapidly changing part of our Earth. Finally, I am involved with the polar version of the regional WRF model that is being developed, tested, and applied to climate variability and change problems in both Polar Regions.
