Research Description

I am interested in soft mesoscopic materials, including colloids, emulsions, polymers, surfactant solutions, non-Brownian suspensions, and gels. I have used and developed light scattering techniques, especially multiple light scattering (duffusing-wave spectroscopy) to study the structure and dynamics of colloids and other materials.  My current research covers a variety of topics, including self assembly, DNA-coated colloids, colloidal swimmers, lock-and-key colloids, random organization, and colloidal glasses.
