An experimental physicist who coauthored the self-assembly of ordered colloidal crystals in a thin nematic liquid crystal. Particles distort the surrounding orientational order and create topological defects; sharing those distortions can bind neighboring particles. The observed structures depended on the type of local ordering, showing how a host material's defects can organize suspended particles into larger patterns.[ref]
