 Research Activities

I’m working on singularity theory and topology. My main subject is the theory of characteristic classes for singular spaces and singular maps, which is deeply connected with the enumerative geometry from classic to modern times. It includes, e.g., CSM class , (singular) Todd class, Hirzebruch class, Schubert calculus, Thom polynomials for singularities of maps. I’m also interested in its applications and real counterpart.
