Eduard Looijenga

Eduard Jacob Neven Looijenga (born 30 September 1948, Zaandam) is a Dutch mathematician who works in algebraic geometry and the theory of algebraic groups. He was a professor of mathematics at Utrecht University until his retirement in 2013.

Looijenga studied mathematics at the University of Amsterdam beginning in 1965, and earned a master's degree there in 1971. He obtained a Dutch fellowship for two years of study at the Institut des Hautes Études Scientifiques in France, and then returned to the University of Amsterdam, earning a Ph.D. in 1974 under the supervision of Nicolaas Kuiper. After postdoctoral research at the University of Liverpool, he took a faculty position at the University of Nijmegen in 1975, returned as a professor to the University of Amsterdam in 1987, and moved again to Utrecht in 1991. Since his 2013 retirement, he has also held a professorship at Tsinghua University.

In 1978, Looijenga was an invited speaker at the International Congress of Mathematicians. He became a member of the Royal Netherlands Academy of Arts and Sciences in 1995, and in 2012 he became one of the inaugural fellows of the American Mathematical Society. In 2013, a conference in honor of his retirement was held at Utrecht University.
