My background is in PDE and functional analysis with applications to invariant manifolds. My research addresses stability, bifurcation, and slow evolution of coherent structures in PDEs describing the evolution of nonlinear waves and gradient flows in polymer materials. Currently I study the development of pore networks in amphiphilic polymer materials used in energy conversion devices such as fuel cells, Lithium ion batteries, and polymer solar cells.
