My Research

lookingI am usually looking for something.

Often it is scholarly in nature.

My main research interest is non-Newtonian fluid mechanics. These fluids flow in a way that is qualitatively different than a viscous fluid like water. I try to understand how they behave.

My work has mainly focused on nematic liquid crystal polymers. They have an internal molecular orientation that depends on how the liquid is flowing, but it in turn feeds back and affects the flow. I try to understand the net result of this interaction, and how it depends on anchoring conditions at hard-wall boundaries and magnetic fields.

I am also interested in electromagnetic wave propagation in anisotropic media, like liquid crystal polymers.
