My research centers on the study of Partial Differential Equations (PDEs) with a particular focus on control theory, including the well-posedness of boundary value problems, controllability, and stabilization. My main research interests are:
Control problems for PDEs on graphs
Stabilization of PDEs in the presence of delay, saturation, or disturbances.
Controllability and stabilization of coupled systems.
