Technical Research Interest:

The research interests of the Mason Group include: (1) nanoemulsions: forming nanoscale dispersions of droplets of one liquid in another immiscible liquid through extreme shear, (2) microrheology: the study of the microscale deformation and flow of nanostructured synthetic and biological materials, (3) LithoParticles: structure of novel colloidal particles dispersed in a liquid solution, and (4) small angle neutron scattering as a probe of the structure of nanoscale hydrocarbon materials and dispersions. Our group thrives on interdisciplinary interactions, and we seek research areas that combine aspects of traditionally different fields.
