Research Interest:
I am currently interested in:

 Strichartz estimates for the linear Schrodingertype equations (fractional Schrodinger equation, half wave equation, higherorder Schrodinger equation) on manifolds.
 Local and global wellposedness, blowup, scattering, stability and instability of standing waves for the nonlinear fractional Schrodinger equation, nonlinear half wave equation, nonlinear fourthorder Schrodinger equation, inhomogeneous nonlinear Schrodinger equation, nonlinear Schrodinger equation with inversesquare potential and system of nonlinear Schrodinger equations.
 Mass concentration of prescribed minimizers for the energy functional related to nonlinear Schrodinger equations, nonlinear Hartree equations, fractional nonlinear Schrodinger equations and SchrodingerPoisson systems.
