I develop scientific principles for understanding complex structure and dynamics in multi-body interacting systems based on experiments involving dispersions of microscale to nanoscale particles, droplets, and polymers. Thermal motion of probe particles in polymer solutions and other complex fluids can be used to measure frequency dependent mechanical response through passive microrheology (Mason & Weitz, Phys. Rev. Lett. 1995; review Squires & Mason, Ann. Rev. Fluid Mech. 2010). Roughness controlled depletion attractions (Zhao & Mason, Phys. Rev. Lett. 2007) have enabled the experimental realization of near-ideal 2D systems of hard Brownian shapes; these systems are yielding new understanding of dense phases and transitions (see e.g. Zhao, Bruinsma, and Mason, PNAS 2011). I am also interesting in understanding how biomaterials, such as DNA and protein, adapt to artificial synthetic geometries. This has led to the creation of nanoscale virus-like droplets (VLDs) that are effectively viral protein cages that self-assemble in the aqueous phase around anionically stabilized oil nanodroplets (Chang et al., ACS Nano 2008).
