Philipp Arras


Announcement: I left academia

I transitioned from my position at TU Munich and the Max-Planck Institute for Astrophysics to Bain & Company as a consultant. My last day at TUM/MPA was on Oct 31, 2022.

If you would like to discuss anything related to resolve, nifty or information field theory in general, please reach out to me.


I did my PhD and postdoc in computational statistics and physics. At the Max-Planck Institute for Astrophysics, I applied Bayesian statistics to imaging algorithms for radio telescopes. I aimed to squeeze out all information present in radio data sets in order to arrive at the highest resolution possible together with uncertainty quantification. To this end, I developed theoretical models for inference algorithms and tailor them for the unification of calibration and imaging, multi-spectral imaging, polarization imaging, data fusion with single dish data and Very Long Baseline Interferometry (VLBI).

These ideas are condensed into various software projects: NIFTy (a Python library for Bayesian inference of fields), resolve (my radio imaging library), vlbi_resolve (the same thing for dynamic VLBI imaging) and ducc (which includes a non-uniform FFT specialized for radio interferometry). I hold a PhD in physics and was part of Rüdiger Westermann’s group (TU Munich) and Torsten Enßlin’s information field theory group (MPA Garching).

During my masters at Heidelberg University I worked on String Theory, Quantum Field Theory and pure maths.
