My research sets the Baum-Connes conjecture (BC) in noncommutative geometry (NCG) as a starting point and aims to study C*-algebras, K-theory, and representation theory from various angles. My current research topics include representation theory on symmetric spaces from the viewpoint of NCG and equivariant K-theory and homotopy theory for finite group actions on C*-algebras.

Miscellaneous
Proper Kasparov Cycles and the Baum-Connes Conjecture (2020) was withdrawn: there are unfixable mistakes in the proof of Proposition 1.6 (at the last equality, page 9) and in the proof of Lemma 1.34 (at the first line, page 30). Lemma 1.34 was crucial for the proof of main theorems, namely Theorem A and B.
