I am a physicist working mainly on the description of quantum many-body systems from a theoretical perspective, for which I use tensor networks. In particular I have been working on the positivity problem, which is the question of how to represent efficiently the positivity of an operator with a tensor network (see here or here or here). I have also been working on continuum limits of matrix product states (see here or here).

In parallel, I have also worked on a notion of universality in spin physics which is somewhat similar to the notion of universality in computer science (by which there exist universal Turing machines; see here).

I am also interested in some conceptual / philosophical aspects in physics. For a gentle introduction to various of these topics, see some of my talks. 

In the past, I worked with Prof. Hans Briegel on a proposal for artificial intelligence called Projective Simulation which has been pursued in many exciting directions (see here).
