Alexander Taveira Blomenhofer, postdoc

Alexander’s research interest lies in tensor decomposition, for which he applies techniques from algebraic geometry and semidefinite optimization. Recently, he derived new bounds on the ranks needed to represent general tensors in various structured tensor decomposition models, which are invariant under a group action.

Alexander received a master’s and a doctorate from the University of Konstanz, Germany, where he was supervised by Markus Schweighofer and co-supervised by Mateusz Michalek.

Alexander then spent 18 months at the Centrum Wiskunde & Informatica in Amsterdam, working with Monique Laurent on sums of squares representations and hierarchies for polynomial optimization on the sphere. He recently turned towards quantum information theory.

In Copenhagen, he will work with Matthias Christandl at the QMATH Centre. You can meet Alexander in Vibenshuset, Lyngbyvej 2.
