Robertus Henricus "Robbert" Dijkgraaf, (; born 24 January 1960) is a Dutch theoretical physicist, mathematician and string theorist and former politician. He served as the Minister of Education, Culture and Science in the Netherlands from 2022 until 2024. From July 2012 until his inauguration as a minister, he had been the director and Leon Levy professor at the Institute for Advanced Study in Princeton, New Jersey, and a tenured professor at the University of Amsterdam. As of January 2025, Robbert is the president-elect of the International Science Council.
Early life and education
Robertus Henricus Dijkgraaf was born on 24 January 1960 in Ridderkerk, Netherlands. Dijkgraaf attended the Erasmiaans Gymnasium in Rotterdam, Netherlands. In 1984, he returned to Utrecht University and obtained an MSc degree in theoretical physics in 1986. He then went on to performing doctoral research under supervision of future Nobel laureate Gerard 't Hooft.
For a few years he worked as a postdoctoral researcher at the Institute for Advanced Study, working alongside Edward Witten.
From 2008 to 2012 he was president of the Royal Netherlands Academy of Arts and Sciences. He was elected as one of the two co-chairs of the InterAcademy Council for the period 2009 to 2013.
Starting in 2012, Dijkgraaf became the director of the Institute for Advanced Study, an independent academic institution located in the town of Princeton, New Jersey. On that date, he stepped down from his position as president of the Royal Netherlands Academy of Arts and Sciences.
He has served on numerous boards including at the Teylers Museum and the NEMO Science Museum. Dijkgraaf's term as minister ended on 2 July 2024, when the Schoof cabinet was sworn in.
Other activities
- Simons Foundation, Member of the Board of Directors (since 2021)
- Scholars at Risk (SAR), Member of the Ambassadors Council
Awards and honours
In 1998 Dijkgraaf was an Invited Speaker at the International Congress of Mathematicians in Berlin.
In 2003, Dijkgraaf was awarded the Spinoza Prize. In doing so he became the first recipient of the award whose advisor also was a recipient (Gerard 't Hooft received the first Spinoza Prize in 1995). He used part of his Spinoza Prize grant to set up a website targeted at children and promoting science: Proefjes.nl.
Dijkgraaf is an elected Member of the Royal Netherlands Academy of Arts and Sciences since 2003 and of the Royal Holland Society of Sciences and Humanities.
On 30 May 2012, he was elected an Honorary Member of both the Royal Netherlands Chemical Society and the Netherlands' Physical Society. On 5 June 2012, Dijkgraaf was appointed a Knight of the Order of the Netherlands Lion. In 2012, he became a Fellow of the American Mathematical Society.
He was elected an Honorary Fellow of the Royal Society of Edinburgh (HonFRSE) in the disciplines of informatics, mathematics and statistics in 2013. That same year, he was elected as Member of the American Philosophical Society.
He received honorary doctorates from the Vrije Universiteit Brussel and Leiden University in 2019. In 2019, Dijkgraaf was awarded the inaugural Iris Medal for Excellent Science Communication, presented at the Evening of Science & Society in the Ridderzaal in The Hague, by Ingrid van Engelshoven, Minister of Education, Culture, and Science, in the presence of King Willem-Alexander.
He was appointed a Foreign Member of the Royal Society in 2025.
Research
Dijkgraaf's research focuses on string theory and the interface of mathematics and physics in general. Their daughter Charlotte was born with a rare type of Leukemia and was the subject of book written by her mother Pia de Jong, Saving Charlotte: A Mother and the Power of Intuition.
