Dr. Ichiro Torisu is currently an associate professor of mathematics at the University of Occupational and Environmental Health. He received Ph. D. in mathematics at Osaka University. The title of his doctoral thesis is “The determination of the pairs of two-bridge knots or links with Gordian distance one”, which concerns a central notion of low-dimensional topology. He studies 3-dimensional manifold topology, knot theory and  contact topology. He teaches geometry, topology, calculus, algebra, ordinary differential equations, statistics in classes. Furthermore in the future, he strongly hopes to combine mathematics with biology and computer science in various aspects.


Research Interest
