Welcome to my website! I am a postdoctoral researcher at the Department of Geosciences at Princeton University. I am interested in all aspects of numerical modeling and parameter estimation that arise within geosciences or related fields. My background is in computational geophysics (PhD at ETH Zurich) and mathematics (M.Sc. at University of Basel).
My current research focuses on the design and implementation of analysis methods for vector fields on the sphere and in particular on the calculation of Earth's and Mars' crustal magnetic field from satellite data.
My PhD at ETH Zurich was in the field of near surface geophysics. In this research project I developed and implemented an adaptive algorithm for electrical resistivity tomography.
You can find more detailed information about my current and past research on my research page. My publications page contains links to pdfs of my published articles. You can download Matlab scripts to generate and use vector Slepian functions from my software page. I continuously update that page and upload new software as soon as it is ready to be published.

My solicited book chapter on using scalar and vector Slepian functions for the crustal magnetic field and gravity field estimation from satellite data that I recently submitted to the Handbook of Geomathematics, 2nd edition is now available on arXiv and on my publications page.
The figure in the background shows a tangential vector field that is bandlimited by the maximum vector spherical harmonic degree 60 and concentrated within North America. It is the 100th tangential vector Slepian function for this bandlimit and target region as is explained on my research page. Its energy focusing ratio is 99.9%. You can calculate and plot this Slepian function with the Matlab function from my software page.
