My research interest is Complex geometry and
Complex analysis, both from the view point of
Nevanlinna theory. In the geometric side, I am
interested in the conjectural second main theorem in
the higher dimensional Nevanlinna theory for entire
holomorphic curves into projective manifolds. Also I
am interested in the behavior of Kobayashi
pseudo-distance of projective manifolds of general
type. These problems are related to an algebraic
geometric problem of bounding the canonical degree
of algebraic curves in projective manifolds of general
type by the geometric genus of the curves. In the
analytic side, I am interested in classical problems of
value distribution theory for meromorphic functions
in the complex plane.
