Research interests:

The goal of my research is to better understand the physical processes that govern the dynamics of ice sheets and glaciers, and to improve the representation of these processes in large-scale ice sheet models. The ice sheets of Greenland and Antarctica together hold the equivalent of 60 m of sea level increase, and understanding their dynamics is essential for projections of future sea level rise. However, many of the processes governing ice sheet dynamics are insufficiently resolved in large-scale ice sheet models. My research projects focus on identifying the main drivers of ice sheet change and deriving parametrizations of these processes suitable for continental-scale ice sheet models.

Current research project: Two-phase dynamics of temperate ice.

Temperate ice is ubiquitous in glaciers and ice sheets, forming where temperatures in the ice sheet reach the melting point. Further addition of heat to temperate ice (for example through internal deformation or warming surface temperatures), leads to the formation of melt water embedded in the ice matrix. Even though the water content within the ice matrix is typically small (a few percent at most), the presence of water drastically alters the mechanical properties of ice. Moreover, water percolating through the ice to the base of the ice sheet can facilitate sliding of the ice along the bed, leading to increased ice discharge. Despite these important implications for ice sheet dynamics, the physical properties of temperate ice are poorly understood. In collaboration with Richard Katz, Ian Hewitt and experimentalists at Iowa State University, I am investigating the interactions between ice and water to develop a two-phase, thermo-mechanical theory for temperate ice flow.
