Research Interest: 
  • Microrheology: measuring the dynamic mechanical shear properties of viscoelastic soft materials over an extraordinarily large range of time scales by optically observing the diffusive motion of micron-sized probe particles embedded in these materials
  • Shear-induced structures in complex fluids: emulsification, shear-banding, shear-ordering
  • Neutron and light scattering from nanomaterials: asphaltenes, clays, droplets, polymers
  • Directed assembly of nanoparticles in solution using shape-dependent attractive interactions
  • Free boundary flows in microfluidic devices
  • Structure and dynamics of soft colloidal glasses
