Studies on the schedule of life history and behavior are :(1) The optimal growth schedule of plants in the fluctuating environments : Stochastic dynamic programming models demonstrated that whether or not growth plasticity is adaptive strongly depends on the mode of stochasticity of environmental fluctuating. From this, stress-tolerant strategy by Grime can be understood from the view of evolutionary ecology.(2) Activity schedule of male butterflies within a day : A game model is examine in which each male allocates its limited time of reproductive activity to optimize his own mating success.(3) Pathogens' optimal growth schedule within the host's body.(4) The evolution of digestive mode and foraging behavior of large herbivorous mammals.(5) Learning of Starlings during foraging in fluctuating environment.(6) The resource allocation models for plants' selfing rate.Other theoretical studies are :(7) Simplification of mathematical models by aggregating variables.(8) A quantity that always increases with time for Markovian transition models.(9) The evolution of mutation rate in fluctuating environments.

关于生命史和行为时间表的研究有：（1）波动环境中植物的最佳生长时间表：随机动态规划模型表明，生长可塑性是否具有适应性强烈依赖于环境波动的随机性模式。由此，可以从进化生态学的角度来理解 Grime 的耐压策略。 (2) 雄性蝴蝶一天内的活动时间表：研究了一个博弈模型，其中每个雄性蝴蝶分配有限的繁殖活动时间来优化自己的繁殖活动。 (3) 病原体在宿主体内的最佳生长时间表。(4) 大型草食哺乳动物的消化方式和觅食行为的进化。(5) 八哥在波动中觅食过程中的学习（6）植物自交率的资源分配模型。其他理论研究有：（7）通过聚合变量简化数学模型。（8）马尔可夫转移模型中总是随时间增加的数量。（9）波动环境中突变率的演变。
