I received my Ph.D. from the Department of Astronomy, The University of Tokyo.
My main research area is galaxy formation and evolution with emphasis on galaxy size.
For the current list of my astrophysics publications, please click here.
Supplementary materials are available here.
Our mass models (GLAFIC team) are available here.
Currently, I am working on the data from the Hubble Frontier Fields.
