"Engineering technologically useful, high performance materials requires nanoscale and/or molecular control of their underlying microstructure. Our research focuses on developing a fundamental understanding of the molecular and nanoscale structure and dynamics of complex materials, especially during flow and processing, which falls under the broader disciplines of rheology, nonequilibrium thermodynamics, complex fluids and soft matter. Our goals include directing molecular and nanoscale self-assembly as a route to engineering novel materials. We are also pioneering new experimental methods for probing nanoscale material structure in collaboration with the National Institute of Standards and Technology (NIST) Center for Neutron Research and Institute Laue Langevin, (ILL) France. Our research has broad application, is supported by the NSF, NASA, NIST, and industry, and includes collaborations around the globe. Translation to practice includes product engineering and entrepreneurial activities through STF Technologies LLC. Teaching interests include Design and Product Engineering, Mass and Heat Transport, Thermodynamics, Colloid and Interface Science and Scattering Methods for Characterizing Soft Matter."
