Research

I am a research professor at Osaka University (Japan), the Graduate School of Information Science and Technology.
My research interests are: Special functions (hypergeometric, Heun, Appell, Painleve), Belyi maps, splines, algebraic geometry, Leonard pairs.
In 2014-2016, I was a researcher at Tokyo University within a JSPS project on computational algebraic statistics.
My PhD thesis (and here is Errata to it ). Written at the University of Groningen in 1995-1999.
Curriculum Vitae .
