T. Sunada\'s work covers spectral geometry, dynamical systems and graph theory. As is seen in his work on isospectral manifolds and dynamical zeta functions, he has a great interest in applications of other fields, say number theory and probability, to geometry. Member of the Editorial Bord of a Japanese mathematical magazine Have Fun with Mathematics (Nihon Hyoron-sha).
