## 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
