Research Outline

My research interests lie in chemical reaction dynamics, kinetics, and networks. I’m working on several research projects related to the development of novel methods for generating and analyzing chemical reaction networks. The details of the projects are as follows.
(a) Development of a theoretical framework for understanding complicated nonadiabatic chemical reaction dynamics from the point of view of chemical reaction networks based on phase space geometry and semiclassical mechanics
(b) Development of automated methods for generating chemical reaction networks that take dynamic effects into account based on phase space geometry and ab initio molecular dynamics
(c) Development of fast computational methods for analyzing and designing large-scale chemical reaction networks using Ising machines
(d) Development of efficient methods for generating chemical reaction networks using quantum computers, Ising machines, and reinforcement learning (under planning)
