I am a physicist and fluid dynamicist at the Niels Bohr Institute, University of Copenhagen. My research concerns the dynamics of nonlinear and anisotropic continua, with particular interest in how microscopic structure influences macroscopic behavior. I develop mathematical models and computational methods to study polycrystalline materials, wave propagation, and geophysical flows.
A major focus of my work is the mechanics of glacier ice and other polycrystalline materials. I study how the evolving orientation and structure of individual crystals can give rise to anisotropic mechanical properties at larger scales, and develop models that connect such material evolution to the dynamics of Earth’s ice sheets and mantle. I also work on electromagnetic and elastic wave propagation in anisotropic media, using observations from ice-penetrating radar and other geophysical measurements to infer properties that cannot be measured directly.
More generally, my research involves spectral methods, nonlinear fluid dynamics, turbulence, porous media, and inverse problems. Across these areas, I am interested in developing efficient mathematical and computational approaches to broaden our understanding of how different scales interact and govern the bulk behaviour of geophysical fluids and solids.
