Research 

One of my research interests is about the connection between nonlinear partial differential equations and geometric quantities such as the curvature and the torsion on almost complex manifolds. In particular, I enjoy working on having a priori estimates for the solutions of these equations. The study of nonlinear partial differential equations on manifolds is a very interesting topic because it is closely related to various fields of mathematics, such as differential geometry, algebraic geometry, and mathematical physics. In addition, I am interested in the characterization of special almost Hermitian metrics on almost complex manifolds and the categorization of almost complex manifolds based on these characterizations, as well as the relations between the geometric properties of almost complex manifolds and the integrability of the almost complex structure. In recent years, I have been researching the existence of warped product submanifolds in nearly Kaehler manifolds, Lorentzian manifolds, and other related settings.
