I am currently an assistant professor at Institute of Science and Technology Austria.
Address: Am Campus 1, 3400 Klosterneuburg, Austria
Office: I21.EG.108
My research area is geometry and topology, which is also related to mathematical physics. Current research interest: configuration space integrals, operads with a manifold structure, real and open Gromov-Witten theory.
