János Kollár

For thirty years János Kollár has researched geometrically oriented algebraic geometry. Besides providing many positive results, he has worked to guide the direction of the field by locating and opening up productive new avenues of investigation. Among other areas, his work has focused on the study of minimal models and their singularities; the analysis of rational and rationally connected varieties; the study of fundamental groups and universal covering spaces of algebraic varieties; the topology of real algebraic threefolds; and compactifications of moduli spaces. He was elected to the Hungarian Academy of Sciences in 1995, the National Academy in 2005,  won the Cole Prize in 2006, the Nemmers Prize in 2016 and the Shaw Prize in 2017.
