Profile
Dr. Yu Kosaka is an Associate Professor at Research Center for Advanced Science and Technology (RCAST), the University of Tokyo. She obtained her Ph.D. at Department of Earth and Planetary Science, School of Science at the University Tokyo in 2007. She worked at International Pacific Research Center, University of Hawaii, and Scripps Institution of Oceanography, University of California San Diego, before moving to RCAST at the University of Tokyo in 2014. Her research focuses on variability and changes of the climate system as natural science. She served as Lead Author of Working Group 1 contribution to the sixth Assessment Report (AR6WG1) of Intergovenmental Panel on Climate Change (IPCC).
Research Interests
As an expert of climate dynamics, she works on continental and ocean basin-scale climate variability and change, through analysis and model simulation of the atmosphere and ocean as a dynamical system. In particular, she is interested in large-scale atmospheric circulation variability and associated atmosphere-ocean interaction.
