Our planet is shaped by the interaction of living things with their physical environment. My interests center on understanding these interactions. Since I trained as an oceanographer, my primary expertise is in how the ocean circulates and influences marine life, climate, and atmospheric chemistry. I got my Ph.D. from the MIT/Woods Hole Joint Program in Physical Oceanography and spent over fifteen years in Princeton at Princeton University and NOAA’s Geophysical Fluid Dynamics Laboratory working to develop computer models of how the planet works. In January 2011 I joined the Department of Earth and Planetary Sciences at Johns Hopkins University.
My group's research is currently focused in three major areas
1. Representing climate processes: Climate models try to faithfully represent physical and biological processs or their impacts. Areas of long-term interest include the representation of turbulence at scales ranging from centimeters to tens of kilometers, capturing the impacts of ocean color and understanding the controls on the growth of phytoplankton.
2. Understanding how these processes shape Earth's climate.I'm interested in the large scale circulation of the ocean and how it interacts with the biosphere and carbon cycle, as well as the role of aerosols such as mineral dust and black carbon.
3. Characterizing variability in the climate system. I'm interested in variability and change on a range of scales, from interannual variability associated with El Nino, to detecting biological and physical changes driven by anthropogenic climate change, to understanding multi-millennial variability in the carbon cycle.
