A Short Biography:

Dr. Mason received B.S. degrees in Physics & Electrical Engineering from the University of Maryland, College Park. He went on to graduate with a M.A. and Ph.D. in Physics from Princeton University.

Awards and Honors:

American Physical Society DFD Gallery of Fluid Motion Award with T. Cubaud ; NSF CAREER Award ; Princeton Joseph Henry Prize in Physics ; Glenn T. Seaborg Award ; Intel New Faculty Award ; Exxon Graduate Research Fellow ; NSF Graduate Research Fellow

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
