My broad area of research is Applied Mathematics with a focus on the Analysis of Partial Differential Equations. Among others, I am working on Nonlinear Partial Differential Equations arising from Quantum Mechanics, Fluid Dynamics, Geophysical flows and more recently Kinetic Models. Questions related to the existence of solutions, their Asymptotic behaviors, and Blow up Analysis are in the core of my research.
