This picture includes our new members, Drs. Steve Penny and Shunji Kotsuki. Dr. Penny is visiting from the University of Maryland for a month, generously supported by a very competitive JSPS fellowship program. He is studying particle filtering methods suitable for high-dimensional spatio-temporal chaos. Dr. Kotsuki just started in January as a full-time team member. He studies data assimilation for hydrological cycle.
