Research Interest: Complex Fluids

The interest of our group is to study the behavior of chemical and biological systems where complex molecules are present. We particularly seek simple models that are able to explain the properties of these systems.

water

  • Why does water have themodynamic and dynamic anomalies? We look for the simple mechanism that explain the presence of such anomalies.



    dna

  • Why does DNA form compact structures? We develop a theory for polyelectrolyte solutions that might lead to a better understanding of the DNA in the presence of salt or organic solvents. We also propose a complex made of one charged polyelectrolyte and amphiphilic molecules. This system has applications for drug deliver mechanism.

    charged colloids

  • When does negative macroions move toward an electric field? We study the charge reversal of charged colloid suspensions.
