My research mainly tries to understand dynamics of probabilities of complex flows. It is about turbulence, many-wave interactions, and effects of complex topography. The practical goal is to improve our ability to predict flows in Earth's oceans and atmosphere, bearing on questions that range from global climate change to local environment.

A particular focus is the Arctic:  how the Arctic works in its heat and water cycles and the role of the Arctic in global ocean and climate. This research involves dynamics of sea ice and snow as well as the liquid Arctic.

The second major theme of current work is predictability: what dynamics set limits on how far one can forecast eddy-active flows. A part of this work includes continuing research into statistical dynamics of flow- topography interactions.

A third item is past climate changes, especially the idea that global changes from cold to warm can be quite rapid whereas warm to cold is slower. From paleo records, can we tell if this story has a basis and, if so, what dynamics may account for the asymmetry?
