I’m interested in biological physics: how simple, predictive laws emerge from messy microscopic interactions. I develop theory and inference tools for networked biochemical and evolutionary systems—linking connectivity to robustness and multistability in chemical reaction networks, characterizing non-classical drift in populations with extreme reproductive variability, and inferring transmission structure from viral allele-frequency time series. I also study information flow in stochastic control networks, aiming for analytic and interpretable descriptions of neural networks.

I received my Ph.D. in Physics from Kyoto University (2013), after completing my M.Sc. (2009) and B.Sc. (2007) in Physics at the University of Tokyo. I was at RIKEN from 2014 to 2022, then held faculty positions at Kyoto University (2022–2025), and I am currently an Associate Professor at Hiroshima University (as of 2026). I was also a Visiting Researcher at UC Berkeley (Hallatschek Lab, 2018–2022).
