Note that I am still at Osaka University and has no plan to move as of November, 2016.
I am a mathematician working for Department of Mathematics, Osaka University as an associate professor. My research area has been the algebraic geometry, the geometry studying shapes or spaces given by polynomial equations; namely, algebraic varieties in technical terms. In particular, singularities of such shapes have been my primary interests. In last years, I mainly worked on problems where the number theory and the singularity theory interplay. Now my interest inclines toward the Diophantine geometry.
Keywords

 jets and arcs
 motivic and padic integration
