Contributions

edit

Kechris has made contributions to the theory of Borel equivalence relations and the theory of automorphism groups of uncountable structures. His research interests cover foundations of mathematics, mathematical logic and set theory and their interactions with analysis and dynamical systems.

Kechris earned his Ph.D. at UCLA in 1972 under the direction of Yiannis N. Moschovakis, with a dissertation titled Projective Ordinals and Countable Analytic Sets. During his academic career he advised 23 PhD students and sponsored 20 postdoctoral researchers.

In 2012, he became an Inaugural Fellow of the American Mathematical Society.[1]
