INTERESTS
Dufresne’s research focuses on understanding, controlling and exploiting the properties of soft materials.
At the macroscale, soft matter exhibits a mixture of fluid and solid properties, while at the microscale its structure and dynamics are dominated by thermal fluctuations. Dufresne’s laboratory manipulates soft materials from the bottom up by altering the interactions of their components and from the top down by applying optical forces.
Current research topics: the structure and stability of colloidal materials in the presence of electrostatic, hydrodynamic, and protein-mediated forces; mechanotransduction in cell biology; plasmon propagation in metallic nanostructures.
