Hi!

I am a Ph.D. research student at BM/d (Biomedical Diagnostics Lab) at the faculty of Electrical Engineering at Eindhoven University of Technology and Philips Research. My expertise is centered at the intersection of signal processing and machine learning. I have been interested in applying these techniques to a variety of applications, including medical imaging and radar.

This website serves two purposes. Beside an overview of my work, I also try to post some interesting articles on things I learned or figured out that might be useful to anyone.
