For the last 16 years I have worked in the physical oceanography group in MIT‘s Department of Earth, Atmospheric and Planetary Sciences (EAPS), and have been affiliated with MIT’s Program in Atmospheres, Oceans and Climate (PAOC), the MIT-WHOI Joint Program (JP), the Climate Modeling Initiative (CMI) , the Center for Global Change Science (CGCS), the Center for Computational Engineering (CCE), and the Program in Computational Science and Engineering (CSE). I did my Ph.D. at the Max-Planck-Institute for Meteorology in Hamburg, Germany.
In the beginning of 2015 I joined the faculty at the University of Texas at Austin, with joint appointments in the Institute for Computational Engineering and Sciences (ICES), the Jackson School for Geosciences (JSG), and the Institute for Geophysics (UTIG). At ICES I am the Fellow of the W. A. “Tex” Moncrief, Jr., endowed chair III in Simulation-Based Engineering Sciences.
My main interest is understanding the general circulation of the ocean and its role in the global climate system. As part of the Estimating the Circulation and Climate of the Ocean (ECCO) consortium that originated under the National Oceanographic Partnership Program (NOPP), we are bringing together a state-of-the-art general circulation model (MITgcm) with most of the available satellite and in-situ observations to produce a best possible estimate of the time-evolving three-dimensional state of the global ocean and sea ice cover. It is now in its second phase, ECCO2.
I’ve also become interested in the cryosphere, in particular in the dynamics of Arctic sea ice and polar ice sheets. We are coupling the MITgcm to a thermodynamic/dynamic sea ice model to improve our simulations of processes in the Arctic and the Southern Ocean. Furthermore, we are investigating the polar ice sheets, their dynamics, their interaction with the ocean, and their contributions to sea level rise. I act as a co-chair of the U.S. CLIVAR working group on Greenland Ice Sheet-Ocean Interactions (GRISO WG) and am member of the newly formed NASA Sea Level Change Team (N-SLCT).
