Joeri van Leeuwen (born 11 January 1975) is aDutchastronomer and formerrower. He is best known for his work on the extreme environments aroundneutron stars. In particular, he works on radio-astronomical studies ofpulsars andfast radio bursts.

Academic career

[edit]

Van Leeuwen obtained his PhD at Utrecht University in 2004, on radio observations of pulsars. He was a post-doctoral fellow at theUniversity of British Columbia withIngrid Stairs, working on pulsar searches using theArecibo Telescope. As aStensen Fellow he next worked atUniversity of California, Berkeley withDonald C. Backer, to build and use theAllen Telescope Array. In 2008 he returned to The Netherlands, as astronomer atASTRON.Van Leeuwen wrote, produced and presented a number of TV programs for large audiences.These include several astronomy series[1] forHet Klokhuis, the educational show on Dutch national TV[2][3].

Research

[edit]

Van Leeuwen's research focuses on explosions around compact objects, especially those visible withradio telescopes.He discovered the first youngneutron star that is so affected by space-time curvature that it has since basically disappeared from sight[4][5].He used theWesterbork Synthesis Radio Telescope andLow-Frequency Arrayto discover thatFast Radio Bursts can be seen at low frequencies, and that their periodicity cannot be explained by simple stellar winds, as was previously thought[6].

Honors

[edit]

Van Leeuwen received a number of awards for his research from theDutch[7] andEuropean[8] Research Councils, and for his outreach from the Netherlands Astronomical Society[9].Asteroid12952 Joerivanleeuwen is named after him[10].

In sports

[edit]

Van Leeuwen is a former professionalrower. He is a two-timeworld record holder[11] with the DutchMen's Eight; he participated in threeworld rowing championships, and won one world-cup medal and multiple national championships.
