I undertake research into nonlinear partial differential equations, employing a combination of analytical and numerical techniques in their study. I am particularly interested in studying free boundary problems arising from thin film flows, including investigations of rupture phenomena, moving contact lines and the effects of surface topography and driving forces upon the motion of the liquid. Such problems often yield evolution equations for the interfacial film thickness in the form of high-order degenerate parabolic equations.
I am currently Chair of the Major in Mathematical Sciences here at Waseda University.

I currently teach classes in multivariable calculus and analysis. I also teach a “reading course” in which students read parts of a popular science book (currently Chaos: Making a New Science by James Gleick) and then in class we explore the mathematics discussed in the book.
I have previously taught classes in single variable calculus, linear algebra, ordinary differential equations, partial differential equations, nonlinear dynamics, computational methods, asymptotics and perturbation methods, and fluid mechanics.
I was awarded the President’s Award for Teaching (Spring Semester 2015) by President Kamata of Waseda University.
An example lecture
In the calculus courses, we start from first principles, proving all of the important results as we progress towards increasingly more advanced concepts.
In 2019, I gave a “non-technical” introductory lecture to prospective students (and families) visiting Waseda University for an open day, as an example of the kind of material that would be presented at the very beginning of an introductory calculus course. This lecture can be found on YouTube as Mathematics in Action.
