A polycrystalline whorl state
When you rotate the particles of a normal crystal, what was once a stable structure can spontaneously fall apart into whorl-like patches…

An odd colloidal liquid
A liquid made up of spinning particles behaves a lot like water - until you take a closer look. Working in the Irvine Lab at the…

Granular statistical mechanics
How do you measure the temperature of a granular packing? To start, it turns out you need to measure the forces. Working with Karen Daniels…

Quasicrystals in liquid crystals
When embedded in a nematic liquid crystal, we found that truncated pyramid-like particles with a pentagonal shape self-organized into…

Photoluminescent nanowires
By growing core-shell nanowires and coating them with silver nanoparticles, we observed plasmon-exciton coupling through photoluminescence…
