-I am a radio astronomer and IT support scientist working at ([[https://www.universiteitleiden.nl/en/science/astronomy|Leiden Observatory]]), the astronomical research institute of [[https://www.universiteitleiden.nl/en|Leiden University]] in the Netherlands. My area of expertise is low-frequency [[https://en.wikipedia.org/wiki/Astronomical_interferometer|radio interferometry]], studying the Universe at radio frequencies below 1 [[https://en.wikipedia.org/wiki/Hertz|GHz]] with telescopes like the Giant Metrewave Radio Telescope ([[http://gmrt.ncra.tifr.res.in|GMRT]]) and the Very Large Array ([[https://public.nrao.edu/telescopes/vla/|VLA]]). These are technically challenging observations to process, complicated by the need to image and deconvolve hundreds of sources in a typical Field Of View ([[https://en.wikipedia.org/wiki/Field_of_view|FOV]]) of many degrees in diameter, the abundant presence of man-made Radio-Frequency Interference ([[https://en.wikipedia.org/wiki/Electromagnetic_interference|RFI]]), and the distorting effects of the Earth's [[https://en.wikipedia.org/wiki/Ionosphere|ionosphere]]. Over the course of several years, I have build and refined a set of software tools to process these observations in an efficient and reproducible way, typically yielding high-quality images. These tools are now systematically applied in many different science projects involving low-frequency radio interferometric observations.+I am a radio astronomer and IT support scientist working at [[https://www.universiteitleiden.nl/en/science/astronomy|Leiden Observatory]], the astronomical research institute of [[https://www.universiteitleiden.nl/en|Leiden University]] in the Netherlands.
