Dr. Matsui focuses on weather and climate sciences linking to aerosol-cloud-precipitation processes and land-atmosphere interactions by development and application of mesoscale meteorological models, satellite remote sensing, and satellite simulators. He is the key developer of the fully coupled NASA-Unified WRF, and deputy (Co-PI) position currently. He is the architect and developer of multi-sensor satellite simulator, the Goddard Satellite Data Simulator Unit (G-SDSU), which plays a critical role to bridge mesoscale models and various satellite missions in NASA, including A-Train, TRMM and GPM missions. Currently, he is a sub-leader of the GSFC mesoscale dynamic and modeling group, and a head committee of the GSFC AeroCenter between 2011 and 2013. He recently initiated a new seminar series of NASA Cloud-Precipitation Center (CPC).  He has been organized AGU session since 2007. He published 50+ journal publications and book chapters.
