During my Ph.D. years I became interested in the theory of algebraic cycles and in its interaction with the theory of motives. In particular, I worked and I am working in the emerging area of non-homotopy invariant motives, a recent development of the theory of Vladimir Voevodsky that is based on insights of Spencer Bloch, Hélène Esnault, Bruno Kahn, Moritz Kerz, Shuji Saito and others.
