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: interfacial forces; self-assembly of colloidal and biological materials; mechanical singularities; mechanics of cells and tissues.
