Research Interests

My research interest in the past concerned the studies of conformal quantum field theory by operator algebraic methods, and in particular their representation theory and end relations to noncommutative geometry and K-theory. Moreover, I dealt with super-KMS properties for graded quantum systems, and again potential relations o noncommutative geometric invariants.

In the current two-years project I would like to intensify the K-theoretic relationships in the case of currents algebra conformal field theories, which connects to the research interests of other members of the Mathematical Physics groups of the School. Moreover, I will deal with quantum stochastic aspects of conformal field theory and noncommutative geometry.
