Professor and Chair of Physics
"I am interested in critical phenomena in liquid crystalline and other soft condensed matter systems. I am currently investigating surface molecular ordering and fluctuations in molecular ordering in liquid crystals near their phase transitions between the disordered liquid (isotropic) and the ordered liquid crystalline (nematic or smectic) states.
With the help of Knox students, I am using a variety of techniques-evanescent-wave ellipsometry, magnetic and electric field-induced birefringence, and light scattering-to probe the molecular ordering near surfaces and fluctuations in bulk samples. The goal of this research is to understand how the length scales and energy scales associated with molecular ordering change in the vicinity of the phase transition."
