I work in the software group of ASTRON in Dwingeloo (The Netherlands) which is part of NWO.
ASTRON builds radio-astronomical hardware and software. The well-known Westerbork and LOFAR telescopes are operated by ASTRON.

I am working and have worked in several projects.

• The design of the Scientific Data Processing (SDP) software for the Square Kilometre Array.
• The software development of ASTRON's LOFAR project, mainly in the development of a highly distributed version of the self-calibration and imaging software to cope with the terabyte-sized data output.
• I have done part of this work at CSIRO's Australia Telescope National Facility (Sydney) as part of the ASKAP project.
• The Casacore project, a general purpose radio-astronomical library. One of the major components is the Casacore Table Data System (CTDS) and its query language TaQL.
  This document compares the features offered by HDF5 and CTDS.
• python-casacore (pyrap) is the Python binding of Casacore. It makes use of Boost.Python

Some tutorial slides are available showing how to use casacore, pyrap, TaQL, and other tools for data inspection and handling.

• Introduction and general concepts.
• casaacore library.
• pyrap (python binding to casacore).
• TaQL (Table query language).
• Miscellaneous tools.
