Below: Computed plasmon-induced Lorentz forces associated with the chiral hybrid modes of a 100x1000-nm nanowire. The net force may pull, spin, or even push the nanowire to the side.

Our research currently resides at the intersection of optics, nanoplasmonics, and nonlinear dynamics.  Of recent interest are metal-nanoparticle dispersions in liquids and solution-processed nanocomposites. 

We currently investigate the thermal, electrokinetic, photo-voltaic, magneto-optical and mechanical behavior of nanocolloids, nanopatterned substrates, and nanoporous glass. Our research involves both experiments and numerical investigations.

What determines the growth or structure of a nanocomposite material? How can we predict and control the patterns and energy flows that emerge within? 

The answers to these questions aid the design and development of next-generation solar cells and organic electronics, sensors, optoelectronic and magnetic metamaterials.
