I am quite interested in putting a firm mathematical foundation on QFT. However, I have not been able to find a professor or an institution doing such a work. Do there exist certain areas of work in which people are engaged in rigorously defining and proving the concepts and contents of QFT? I am just very curious.

Are there some efforts to add rigor to the quantum field theory?
