Interested in mathematics, especially in differential geometry and function theory of several complex variables. My work centers around asymptotically symmetric spaces and their conformal infinities.

From Sep. 1, 2017 until Aug. 29, 2019, I'm away from Osaka and working as:
- May 13, 2018 — A preprint entitled “A construction of Poincaré-Einstein metrics of cohomogeneity one on the ball” is uploaded on arXiv. Pedersen's construction (1986) of Poincaré-Einstein metrics on the 4-ball with the Berger spheres at infinity is generalized to higher dimensions.
- Apr. 10, 2018 — I added a survey article on Einstein ACH metrics on arXiv. This is a contribution to the proceedings of the KSCV conference, in which I gave a talk in July 2016. Several open problems are discussed.
- Jan. 16, 2018 — Taiji Marugame kindly pointed out some misprints and computational errors in my thesis. (They are all minor, and the main content of the thesis needs no modification.)
- Jan. 16, 2018 — We organized the workshop “Geometric Analysis in Geometry and Topology 2017” on December 19–22 last year (my “Foundations and developments of Poincaré-Einstein metrics” was a part of it). The notes offered by the lecturers are made public here.
- Jan. 9, 2018 — The notes prepared for the lecture “Foundations and developments of Poincaré-Einstein metrics”, which I gave in December last year in Tokyo, is now available.
- Sep. 1, 2017 — I arrived at Stanford University as a two-year visitor.
