I'm a scientist interested in Earth's climate system as a whole. Most of my work is focussed on the oceans, their physics, biology, chemistry and variability on decadal to millennial time scales. I try to understand the causes for today's global deep overturning circulation, how and why it has changed in the past, how it may change in the future due to natural or human influences, how it impacts climate, ecosystems and biogeochemical cycles including isotopes. Click on the PROJECTS link above to find out more about current projects. I develop, improve, analyze, and use numerical (computer) models. The code I develop is available and free for everybody do download and use. Click on the MODELS link above or contact me if you're interested.

Opportunity for Post-Doctoral Research

I'm looking for a post-doctoral researches to work on a project to quantitatively understand the ocean's circulation and carbon cycling during the Last Glacial Maximum and subsequent deglaciation. More info is available here.
