Hiraku Nakajima was born in Tokyo, Japan. He received his Ph.D. in 1991 from the University of Tokyo. Nakajima began his academic career as a research assistant at the University of Tokyo. From 1992 to 1995 he was an assistant professor at Tohoku University’s Mathematical Institute. In 1995 he returned to the University of Tokyo, where he served as an assistant professor. In 1997 he moved to Kyoto University and, in 2008, he became professor at Research Institute for Mathematical Sciences. Lastly in 2018, he became professor and principal investigator, at Kavli Institute for the Physics and Mathematics of the Universe in 2018. Nakajima received both the Geometry Prize (1997) and the Spring Prize (2000) from the Mathematical Society of Japan. He was a plenary speaker at the International Congress of Mathematicians (Beijing, 2002). He has also received the 2005 JSPS Prize of the Japan Society for the Promotion of Science, the 2014 Japan Academy Prize, and the Asahi Prize. Nakajima’s research interests include geometry, representation theory, and mathematical physics. He is particularly known for the development of the theory of quiver varieties. Other major accomplishments include his proofs of Nekrasov’s conjecture and the AGT conjecture, both geometric conjectures which originated in physics.
