My research interest is food security. I think that one of the most important tasks for sustainable society is securing of stable supply and equal distribution of food. Especially, my current research topic is mainly developing next-generation crop model and the relationship between climate change and crop productivity. My research background is ecology and applied statistics. Using the methods of statistics and modeling and taking advantage of my background of ecology, I am working on the tasks.
