Taketo Sano

I am a postdoctoral researcher at RIKEN iTHEMS since April 2022. I received my PhD in 2022 from the University of Tokyo under the supervision of Prof. Mikio Furuta.

My research field is low-dimensional topology, and particularly interested in Khovanov homology theory.

I have worked as a software engineer for 9 years, prior to entering the master's course in 2016. I am a father of an 8 year old girl.
