He then went on to performing doctoral research under supervision of future Nobel laureate Gerard 't Hooft.

[4] The original arrangement was that only one of the trio would work on string theory, but all three ended up writing their thesis on this subject.

[citation needed] His thesis was titled A Geometrical Approach to Two Dimensional Conformal Field Theory.

This bill would allow colleges and universities to limit the number of foreign students they accept, and it would enforce stricter regulations on using the Dutch language in academic studies.

He used part of his Spinoza Prize grant to set up a website targeted at children and promoting science: Proefjes.nl.

[19] He was elected an Honorary Fellow of the Royal Society of Edinburgh (HonFRSE) in the disciplines of informatics, mathematics and statistics in 2013.

[2] He is best known for his work on topological string theory and matrix models, and his name has been given to the Dijkgraaf-Witten invariants and the Witten-Dijkgraaf-Verlinde-Verlinde formula.

[25] Dijkgraaf has co-authored and published more than 70 research articles in the field of string theory and physics, with many other researchers including: Cumrun Vafa, Lotte Hollands, Erik Verlinde, Herman Verlinde, Hirosi Ooguri, Gregory Moore, Rajesh Gopakumar, Sergei Gukov, Miranda Cheng, and others.
