Born 21 June 1974. Natasha Dobrinen is a professor of mathematics at the University of Denver.

Her research interests are in set theory and its connections with other areas of mathematics. Past work has involved Boolean algebras, combinatorial set theory, large cardinals, and recursion theory. She is currently working on classification of ultrafilters under Tukey reducibility, and also in Ramsey theory.

She received her PhD in 2001 from the University of Minnesota, under the supervision of Karel Prikry. She has held postdoc positions at The Pennsylvania State University, working with Stephen G. Simpson, and at the Kurt Goedel Research Center for Mathematical Logic in Vienna, working with Sy-David Friedman.

Natasha Dobrinen: Ramsey Theory of the Henson graphs

Abstract: A central question in the theory of ultrahomogeneous relational structures asks, How close of an analogue to the Infinite Ramsey Theorem does it carry? An infinite structure S is ultrahomogeneous if any isomorphism between two finitely generated substructures of S can be extended to an automorphism of S. continue reading…
