Karl Sigmund

Karl Sigmund (b. July 26, 1945 in Gars am Kamp, Lower Austria) is a Professor of Mathematics at the University of Vienna and one of the pioneers of evolutionary game theory.

Sigmund was schooled in the Lycée Francais de Vienne. From 1963 to 1968 he studied at the Institute of Mathematics at the University of Vienna, and obtained his Ph.D. under the supervision of Leopold Schmetterer. He spent his postdoctorate years (1968 to 1973) at Manchester ('68-'69), the Institut des Hautes Etudes in Bures sur Yvette near Paris ('69-'70), the Hebrew University in Jerusalem (1970-'71), the University of Vienna (1971-'72) and the Austrian Academy of Sciences (1972-'73). In 1972 he received habilitation.

In 1973, Sigmund was appointed C3-professor at the University of Göttingen, and in 1974 became a full professor at the Institute of Mathematics in Vienna. His main scientific interest during these years was in ergodic theory and dynamical systems. From 1977 on, Sigmund became increasingly interested in different fields of biomathematics, and collaborated with Peter Schuster and Josef Hofbauer on mathematical ecology, chemical kinetics and population genetics, but especially on the new field of evolutionary game dynamics and replicator equations. Together with Martin Nowak, Christoph Hauert and Hannelore Brandt, he worked on game dynamical approaches to questions related with the evolution of cooperation in biological and human populations.
