My research focuses on cosmology and cosmological structure formation, especially topics related to dark matter and dark energy. I study the dark universe mainly using gravitational lensing, taking both theoretical and observational approaches. I developed glafic, a software for analyzing gravitational lensing, and am also heavily involved in various wide-field imaging surveys such as the Subaru Hyper Suprime-Cam (HSC) survey and the Euclid satellite mission. You can find my CV for more details.
