Research interests

I am currently employed as a PhD student at the department of Geoscience at Aarhus University in Denmark. Most of my research focuses on the numerical study of glacier and landscape evolution but my research interests are much more broad,

  • High viscosity fluid flows
  • Numerical solvers
  • Glacial hydrology
  • High-performance computing
  • GPGPU computing
  • Big data
  • Landscape evolution and glacial erosion

My current research focuses on developing a graphical processing unit (GPU) based numerical solver for the integrated Second-Order Shallow Ice Equations (iSOSIA) (Egholm, 2012). The glacial flow problem is very computationally expensive. In particularly when investigating landscape evolution where large mountain ranges are simulated for millions of years. With the newest advances in high-performance computing we have been able to reduce this computational time from weeks to days. This either allows for a faster “turn over time” between different model parameters or the possibility to increase the complexity of the models.
