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 The wild McKay correspondence for cyclic groups of prime power order (joint work with Mahito Tanno) is now on arXiv. 2020/06/23
- start to work at Osaka University. 2020/04/01
- put a new preprint Moduli of formal torsors II (joint work with Fabio Tonini) on arXiv. 2019/09/20

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.
