Studies of Gels
Our primary interest is in gels, which are found in numerous products of daily use. These have fascinating visco-elastic properties, fundamentally different than solids or liquids. My laboratory is devoted to interdisciplinary research ranging from Polymer Physics to Biophysics. Through a variety of experimental methods such as light scattering, small-angle X-ray and neutron scattering, and microscopy complemented by computer simulations of model gels, my group has elucidated the structure of gels at the molecular level, the physics of gel formation, diffusion in gels and the kinetics of phase transitions and chemical reactions in gels. Current research projects include the phase behavior of multiblock copolymer gels and their application to develop templates for nanoscale devices.
