Biographical Sketch

My main interest exists for the development of mechanistic models of ecosystem structure and functioning. Indeed, I have been developing the SEIB-DGVM, which simulates plant and carbon dynamics under specified climatic conditions.

During the last several years, I focused on Siberian larch forest, which is the world largest coniferous forest. With its huge area and vast potential carbon pool within the biomass and soil, and with forecasted intensive warming on high latitudinal areas, Siberian larch forest will likely play a major role in the global carbon and energy balances under changing climate. To address its uncertainty, I have further developed the process-based approach by integrating the SEIB-DGVM with the Noah land-surface-model, which simulates soil freeze-thaw processes.

I am also interested in cooperation with field-ecologists, and hence I usually make model codes and related technical materials available on the web as public domains. I believe promoting such open science is vitally important especially for model scientists, since it is essential to accumulate knowledges of many field researchers in order to enhance the reliability of the models, those are intended to reproduce diverse and complex terrestrial-ecosystems.

[Figure] A snap shot of the simulated forest stand (30m*30m of tempelate mixed-forest) of the SEIB-DGVM. Because spatial hetero-structure plays a central role in vegetation dynamics, this model explicitly treat forest 3D structure using individual-basis modeling approach. Individual tree is composed of crown, stem, and root. Shape of crown and stem are approximated by cylinder.
