Andreas Naes Aaserud was born in New York, USA, on September 10, 1987, to Norwegian parents, but grew up in Copenhagen, Denmark, where he lived until he was accepted into graduate school at UCLA in Los Angeles, USA, in August, 2011. Since October 2016, he has been a research associate (postdoc) at Cardiff University under the supervision of Professor David E. Evans.
Overview of research activities
At UCLA, Andreas’ research focussed on ergodic theory and von Neumann algebras, and especially on the use of von Neumann algebras in studying measure preserving actions of countable discrete groups. His PhD thesis was titled “Weak and approximate equivalence of group actions in the framework of ultrapower Cartan inclusions” and was based on joint work with his advisor, Professor Sorin Popa, concerning some new notions of equivalence of group actions, namely approximate versions of conjugacy and orbit equivalence that were defined using ultrapowers of von Neumann algebras. Currently, Andreas is working on a K-theoretical project with Professor David E. Evans inspired by subfactor theory.
