I am a mathematician working in Sendai, Japan. My speciality is Algebraic Geometry, which is a study of shapes given by polynomial equations. My recent studies are about what might be called *Arithmetic Singularities*, that is, a study of relation between singularities of such shapes and the number theory.

Keywords of my works include:

singularities, jets and arcs, motivic and p-adic integration, the McKay correspondence, rational points, higher Semple-Nash blowups and F-blowups, wild quotient singularities, counting field extensions
