I am broadly interested in geophysical fluid dynamics, that is, the behavior and attributes of stratified flow in shallow layers on the surface of the rotating Earth. A large part of ocean dynamics can be described as either wave-like, such as surface and internal tides, or eddying, such as the mesoscale circulations, and I am interested in the interactions of these dynamics insofar as they influence coastal sea level or can be measured by satellite altimeters. I am also interested in the problems associated with ocean prediction, in which our theoretical understanding of the ocean and its interactions with other climate systems is applied to forecast future ocean sea level, currents, temperatures, etc. Ocean monitoring and forecasting are likely to be of growing societal relevance as changes in the coastal zones increasingly interact with our economic infrastructure.
Scientists with NASA’s Oceans Melting Greenland mission are probing deep below the island’s warming coastal waters to help us better predict the rising seas of the future.
As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise contribution.

At this year's American Geophysical Union (AGU), researchers are highlighting how an ice-measuring mission is helping to understand aspects of our home planet far beyond what it was intended to do.
Launched on a Falcon 9 rocket Nov. 21, the U.S.-European satellite will measure the world's ocean with unprecedented accuracy.
High-tide flooding is an increasing fact of life for U.S. coastal areas. A new tool developed with NASA funding projects its annual frequency for 97 U.S. cities and how it will change over time. (Image credit: B137, CC BY-SA 4.0, via Wikimedia Commons)
