Past studies

POPULATION/COMMUNITY DYNAMICS

• L-shaped size distribution in plant population
• Population dynamics of plants
• The relationship between projection matrix models and diffusion models
• Invasibility in density-dependent projection matrix models
• Stochastic forecasting of population dynamics in varying environment

EVOLUTION

• Attainability of Nash equilibrium in coevolution game
• Optimal strategy of leaf expansion and shedding in trees
• Evolution in reproduction frequency in plants
• Optimal allocation to seed or vegetative reproduction
• Necessary condition for delayed reproduction
• Dispersal strategy under disturbance

Present Research Interests

• Forecasting of the dynamics of plant population (especially PVA: population viability analysis)
• Sustainable mechanism of species diversity in forest community
• Optimal leaf longevity of trees under seasonally varying environment
• Meta-analysis of big data on population dynamics
• Mathematical analysis of random matrix in populations
