About me

A. R. OffringaHi! My name is André Offringa. I'm an astronomer and work as a tenure-track associate scientist at the Netherlands Institute for Radio Astronomy (ASTRON) since 2014. I'm interested in the Epoch of Reionisation (EoR), which is a period in the evolution of our Universe in which the first objects started to heat our universe. I am part of the management team of the of the LOFAR EoR project, an exciting project that uses the LOFAR telescope to detect signals from the early Universe.

From 2012 to 2014, I worked as post-doctoral fellow at Mount Stromlo Observatory, a research school of the Australian National University in Canberra. There, I worked on the Murchison Widefield Array interferometric telescope to make a statistical detection of the Epoch of Reionisation.

I'm also involved in the analysis and mitigation of Radio-Frequency Interference (RFI): my PhD thesis at the Kapteyn Astronomical Institute (2008-2012) was about this topic. Finally, I work on imaging & calibration algorithms. You can find articles I wrote on the publications page.

In my free time, I practise ballroom dancing. I teach ballroom at Student Society 'The Blue Toes'.

Software products & interests

For my work, I write a lot of scientific software. One of the tools I wrote is the AOFlagger, a platform to mitigate radio-frequency interference from interferometric or single-dish observations. I also wrote two interferometric imagers: a fast imager called WSClean and an interferometric imager that does not require gridding of the data in uv-space. Both are aimed at doing widefield synthesis.

Most of the time, I use the C++ programming language for developing software, of which I am a big fan. I like reading about the standardization and the C++11 / C++14 standards.
