## Research Activities

**Areas of Expertise**

Classical Analysis, Functional Analysis, Partial Differential Equations

**Current Interests and Activities**

My current interests are, in particular, hyperbolic and dispersive waves in non-homogeneous nonlinear equations with regards to the existence, stability of solutions, and bifurcations.

I am also interested in Experimental Design and Multivariate Analysis as well as Mathematics Education.
