Research in Naithani research group focuses on three complementary themes: (1) understanding spatio-temporal dynamics of ecosystem structure and function, 2) upscaling carbon and water fluxes from plants to landscape, and 3) understanding and modeling the influence of disturbance and global change on socio-ecological systems. All current and past projects combine field and modeling approaches.
