Research interests

Theoretical condensed matter physics, weakly-connected matter.

His research concerns the statistics of "structured" fluids, containing polyatomic species such as polymers, surfactant micelles or colloidal particles, and aggregates. One current interest is heterogeneous polymers, in which competing interactions give novel structures and metastability to a polymer fluid. He is studying new structures that such polymers take on when they are near a solid substrate and the consequences of topological and twisting constraints in polymer fluids. He is also studying the mechanics of crumpled elastic membranes, surfactant monolayers and granular materials. He wishes to understand the distinctive ways in which stress propagates and relaxes in these materials to give them their distinctive strength characteristics.
