My main research focuses on two distinct areas: physics of the early Universe and topological quantum computing. In particular, I'm trying to find out whether the dark sector of our universe can arise from some modified gravity theory and purely gravitational degrees of freedom. In the field of topological quantum computing, I am interested in what properties a certain topological quantum field theory should have in order to efficiently perform quantum computing using the device it describes.
