Joris' Research Page


This page is - like the research itself - in a continuing state of evolution and may therefore neither be complete, not up-to-date. Please do feel welcome to contact me with any questions or when I need a nudge to update anything.


I am currently a Marie-Curie post-doctoral researcher at the Max-Planck-Institute for Radio Astronomy in Bonn, Germany, where I use the Effelsberg 100-m radio telescope to search and time millisecond pulsars (MSPs) within the wider framework of the European Pulsar Timing Array .

Before moving back to Europe, I was a post-doc for a year at West Virginia University in the U.S.A. and before that still, I did a PhD as part of the Parkes Pulsar Timing Array (PPTA) project, in Swinburne University of Technology and the Australia Telescope National Facility (ATNF) in Australia. My thesis "Long-Term Timing of Millisecond Pulsars and Gravitational Wave Detection", can be downloaded from astro-ph.

Recent and Ongoing Research Topics

As always, a couple of research projects are going on in parallell. In order of prioritisation, these are the things I am working on as of January 2010.

(Note I provide this information voluntarily and in good faith, assuming stealing projects & ideas as well as agressive scooping do not occur amongst civilised people. Please don't disappoint me!)

Then there are a few projects that are on the back burner for now, but which I am hoping to get finished in the not-too-distant future. Note that I am not necessarily the lead investigator for all the following projects.

Past Research in Astronomy

Brief Professional History

1998-2000: I was a member of the Urania Public Observatory, Antwerp, Belgium and took a few introductory evening courses in astronomy there.

2003-2004: The "Master of Science in Advanced Techniques in Radio Astronomy and Space Science" was my real start in (radio) astronomy. The follow-up programme currently being organised at Chalmers University in Göteborg, Sweden, provides the same strong basis that got me started. Another useful link in this context is the Alumni Organisation that I founded together with some of my classmates. My Master's Thesis Satellite Interferometry Simulations can be found here

2004-2005: My first experience in Australia was the ATNF Summer Vacation Programme, where I reduced some ATCA H I data of dwarf irregular galaxy UGCA 438, under supervision of Jürgen Ott.

2005-2009: I worked on my Ph.D. thesis "Long-Term Timing of Millisecond Pulsars and Gravitational Wave Detection" at Swinburne University of Technology in Melbourne, Australia, under supervision of Prof. Matthew Bailes. I was also co-supervised at the Australia Telescope National Facility (ATNF) in Sydney, Australia, by Dr. Richard Manchester and with much help and (both moral and scientific) support from Dr. George Hobbs. I was lucky enough to spend many days, nights and - everything added together - quite a few kilohours observing at the Parkes Radio Telescope.

2009: I worked as a postdoctoral research associate at West Virginia University in Morgantown, U.S.A. Because my stay was only short, I focussed on a few simulation-based statistical analyses of the pulsar population. One of these deals with parallax biases and has been published (see above), the other one relates to the pulsar spectral index distribution and is still ongoing.
