I am currently a Ritt assistant professor at Columbia University.

I work in representation theory, with a focus on geometric and diagrammatic techniques. I completed my PhD at Stanford University under the supervision of Zhiwei Yun. In Spring 2018, I was a Strauch postdoctoral fellow in the MSRI program in representation theory.

### Stuffs

Because this seems to confuse many people, including some of my collaborators: "Makisumi" is my last name. I usually go by "Macky," an anglicisation of my Japanese nickname "Makkī" (マッキー), which comes from the first part of my last name.

I did my undergraduate studies in math at Princeton University. Even earlier, in high school, I went to the Canada/USA Mathcamp summer program. It's awesome.
