Helgeson's research is devoted to the design and processing of complex fluids, especially those involving colloidal species (nanoparticles, emulsions, proteins, etc.) in self-assembling & structured liquids. Specifically, the group seeks to understand how well-specified mesostructure can be obtained in these fluids, and how it can be used to control the mechanical and transport properties of soft materials. Their approach involves combining experimental and theoretical tools (scattering, microscopy, rheology, statistical & colloidal thermodynamics) for multi-scale characterization and description of fluid microstructure and dynamics, ultimately to inform the molecular-level design of mesoscale structure. The group has particular expertise in developing methods for in situ monitoring of fluid microstructure during processing. Current projects include the design of functional and stimuli-responsive gels and particulates for applications in biotechnology, advanced materials and energy conversion.
