Zin Arai

Zin Arai is a Professor in the Department of Mathematical and Computing Science at the School of Computing, Institute of Science Tokyo (formerly Tokyo Institute of Technology). He serves as Research Supervisor for JST PRESTO's 'Mathematical Sciences for the Future' initiative. His research centers on dynamical systems using topological and computational methods, with applications spanning chemistry, biology, and engineering.

Key research areas include:

• Dynamical systems theory (Hénon maps, hyperbolic dynamics)
• Computational topology (Conley index, validated numerics)
• Interdisciplinary applications (primate social behavior, chemical reaction dynamics)

His 15 most recent publications (2007–2025) demonstrate consistent focus on rigorous computational methods, bifurcation analysis, and topological approaches to nonlinear systems. Notable tools developed include programs for parameter space analysis of Hénon maps and tangency verification.

As JST PRESTO supervisor, he oversees projects advancing mathematical sciences. No explicit lab affiliation or awards are documented, but his computational work supports broad scientific collaboration.
