Important Note!

A number of news stories (starting with an article on Fox News) appear to have emerged that seem to suggest that the results of our recent paper ( indicate the coming of a new ice age. These articles are utterly misrepresenting our results. Our study examines the physical mechanisms that may have contributed to past glacials; it does not in any way suggest that we may presently be heading towards another ice age.

Research Interests

My research aims to improve our understanding of the dynamics of the oceans, the atmosphere, and the coupled climate system. I am particularly interested in the processes that govern the transport of heat and other constituents in the ocean. Understanding the mechanisms of these transport processes is key to our understanding of changes in the climate system during Earth’s past and future. I tackle these questions using a combination of theoretical fluid dynamics, numerical simulations and analysis of observational data.
