RESEARCH INTERESTS

My research interest is resource management and I have built simple models that focus on resource users’ behavior or decision-making. For sustainable resource use, it is important to foster cooperative behavior because people (resource users or stakeholders)’s response can make difference in resource use. Previous projects applied a. widely accepted approach based on benefit maximization, b. searched way to enhance cooperative behavior, c. heterogeneity among people when they adjust strategies for improving their own benefit. Study of resource management raises critical problems in our society such as property right, rule crafting, punishment, etc which are essential for understanding of cooperation. Next goal in my study will be related those fundamental questions.

This figure illustrates the main result of the recent work (published in J. Theor. Biol.) which discusses the scheme of punishment, called graduated sanction. Sanction takes a greatly important rule for cooperation maintenance by affecting payoff function of each player. Long-lasting common resource management has known to have such a scheme of sanction (Ostrom, 1990) but this is not well explained in theoretical studies. We suggest conditions where this rule of sanction works efficiently with the assumption of pool punishment.

RESEARCH INTERESTS

The goal of my research is to provide insight into clinical diagnosis and managements of patient by using mathematical methods.

I am especially interested in identifying dynamics of cancer and optimum therapeutic interventions, which can be tested in the clinic.
