Welcome to the homepage of Martin Groenewegen.

As of February 1st, 2008 I hold a permanent position at the Koninklijke Sterrenwacht van België (Royal Observatory of Belgium, ROB) in Brussels, and since September 2018 I am the head of the operational directorate "Astronomy and Astrophysics", one of the four departments of the ROB.

Between 1 Oct. 2001 and 31 Jan. 2008 I worked for the Herschel-PACS ICC (Instrument Control Centre) at the Instituut voor Sterrenkunde (IvS) of the KU Leuven in Belgium.

Between 1 Oct. 2000 and 30 Sep. 2001 I was an associate in the ESO Imaging Survey (EIS)-team.

I held a post-doc position at the MPA (Max-Planck-Institut für Astrophysik) in Garching from 1 October 1995 to 30 September 2000..

Between 1 Nov. 1993 and 30 Sep. 1995, I was a post-doc at the IAP (Institut d'Astrophysique de Paris).

I obtained my PhD on 28 September 1993 from the University of Amsterdam.

In 2021 Stanford University released a list that represented the top 2% of the most-cited scientists in the world in various disciplines. Two of the researchers who made it onto the list come from the Royal Observatory of Belgium: VĂ©ronique Dehant and myself. Here is the interview that we did for the ROB external communication service.
