I am an associate professor of mathematics. I obtained my PhD in Computational and Applied Mathematics from Rice university. LAU has been my second home since 2011, where I enjoy teaching various courses such as multivariate calculus and partial differential equations.

In my free time, I enjoy discovering and reading about new science, talking about math/science while sipping coffee, teaching maths to my six years old, and mostly injecting these passions into my everyday life.

Research Interests and Projects

I am interested in ocean modeling and have been working on some applied projects such as modeling surface currents and understanding pollutant transport in our part of the Mediterranean Sea. I also work on the development and solution of perturbation based models for unsteady pressure driven flows in long channels of variable cross-section.
