Research Interests:

During my PhD, I studied string theory and quantum gravity, and now I am studying theoretical biology. Especially, I am interested in evolutionary dynamics and also interested in dynamics of biological network systems, such as gene regulatory networks, metabolic networks, and signal transduction networks.
