 Research Activities
 My research interests lie in the field of dissipative linear and nonlinear hyperbolic PDEs. The study of such equations has been inspired by theoretical physics. Indeed, hyperbolic equations arise in some of the fundamental
theories including general relativity, quantum field theory, electrodynamics, acoustics and elasticity.
My recent work concerns two problems: (1) global wellposedness for nonlinear wave equations with critical and supercritical damping and (2) asymptotic behavior for dissipative wave equations related to the socalled diffusion approximation of damped waves.
