What I’m working on

Lately most of my work is about AI agents that do real work for a business, not just answer questions.

That takes three things: knowledge of the domain, a reliable place for the agent to run, and a way for people to check what it did. Several of my own projects already run this way, and so does our work at Tokuma Labs.

If you have work that could be an agent’s job, I’d like to hear about it.

Genetics and bioinformatics

Before founding anything, I spent three years at Osaka University: first at a lab bench in molecular genetics, then in bioinformatics.

My research reconstructed the 3D shape of chromatin, the way DNA folds inside a cell nucleus, from the contact data that experiments measure. A genetic algorithm searched for the shape that best explains the contacts. The paper appeared in IEEE/ACM Transactions on Computational Biology and Bioinformatics in 2019.

The code, from 2017

The contact map: which parts of the strand touch. This is what an experiment gives you.

The shape you infer from it. Drag to turn it; it refolds when you let go for a while.

Off the clock

Onsen, mountain trails, and long walks through towns I haven’t seen yet.
