Freek Roelofs

Center for Astrophysics
Postdoctoral Researcher


Freek Roelofs obtained his PhD degree at Radboud University in the Netherlands in 2020. His general research interests include simulation and analysis of Event Horizon Telescope (EHT) data and of future Very Long Baseline Interferometry (VLBI) array concepts. He is an expert in geometric modeling, time domain analysis, and imaging. He has developed software to simulate EHT observations as realistically as possible. He also developed a novel Space VLBI mission concept aimed at obtaining ultra-high resolution images of black hole shadows. He is actively involved in the Next-Generation Event Horizon Telescope (ngEHT) project, where he leads the Analysis Challenges, in which participants analyze simulated datasets as best they can. This process helps improving both the array concept and the analysis algorithms.
