Welcome to my research website. I am a community ecologist studying changes in biodiversity across space and time. I work on developing new quantitative methods to disentangle the complexities underlying ecological community structure and ecosystem functioning. I am also interested in applying ecological theory to ecosystem management under global change.
I co-run the Laboratory of Forest Ecology, Graduate School of Agriculture, Kyoto University, with Prof. Yusuke Onoda. I serve as an associate editor for Journal of Ecology, Ecological Solutions and Evidence, and Journal of Forest Research.
