Interests
I study the physics and dynamics of Earth's climate and its response to external forcings, including abrupt changes in carbon dioxide concentrations, historical greenhouse gas and aerosol levels, future emission scenarios, and orbital cycles that alter incoming solar radiation. I focus on interactions among the atmosphere, ocean, cryosphere, and land across a variety of timescales ranging from days to millennia. My work spans multiple areas within climate science, with particular emphasis on the general circulation of the atmosphere and oceans, polar climate and sea ice, climate feedback mechanisms, the hydrological cycle, and energetic processes in the land, ocean, and atmosphere.
I use a range of computational tools and techniques, including comprehensive Earth system models, targeted experiments with climate models of varying complexity, mathematical conceptual models that provide simplified representations of underlying physical processes, and advanced statistical methods. These tools and techniques together allow me to develop theories that explain observed physical phenomena and the behavior of climate models.
Climate science is inherently interdisciplinary, as the atmosphere, oceans, cryosphere, and land are intimately coupled and influence Earth’s climate on a range of timescales. I enjoy working and collaborating on research questions at the intersection of these components.
