Since 2012, I have been working towards overcoming the significant technical and logistical challenges of using the longest baselines of the International LOFAR Telescope (ILT). With telescopes spread up to 2,000 km away from each other, the ILT is a massive telescope which can provide exquisite resolution, but calibrating the data from these distant telescopes is not easy.

I currently Chair the LOFAR VLBI (Very Long Baseline Interferometry) working group and lead the commissioning for VLBI pipelines to be used for LOFAR2.0 (an upgrade to the telescope which will expand its sensitivity).

In 2022, I led a Special Issue in Astronomy and Astrophysics which focused on sub-arcsecond resolution imaging with the ILT.  

In 2025, I led a review of A decade of sub-arcsecond resolution imaging with the International LOFAR Telescope.
