I am a mathematician working in Osaka, 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

- a new preprint On the behavior of stringy motives under Galois quasi-étale covers (joint work with Javier Carvajal-Rojas) is now on arXiv. 2021/05/12
- posted the manuscript "Greatest common divisors and plane curves". 2020/12/05
- a new preprint The wild McKay correspondence for cyclic groups of prime power order (joint work with Mahito Tanno) is now on arXiv. 2020/06/23

I signed on The Cost of Knowledge of Aug. 5, 2015. I would like to refrain from cooperating with Elsevier by publishing, refereeing or doing editorial work.
