Research Interests

Algebraic combinatorics is my research area, with the focus on Jones pairs, type-II matrices and their relations to association schemes. Association schemes encode combinatorial objects such as distance regular graphs and symmetric designs. They can also be viewed as a generalization of finite abelian groups. Two families of association schemes, the Johnson schemes and the Hamming schemes, have applications in the study of designs, codes and orthogonal arrays. My interest lies in the connections of association schemes with coding theory, design theory, graph theory and knot theory.
I am also interested in algebraic graph theory, quantum walks on graphs and complex Hadamard matrices.
