Research Interests

  • Polymer adsorption at solid/liquid and liquid/liquid interfaces
    a)   kinetic studies using second harmonic generation, ATR-FTIR, and interfacial tensiometry
    b)   equilibrium measurements using interfacial tensiometry and AFM
  • Protein adsorption at liquid/liquid interfaces in the presence of interfacial polymeric films
    a)   effects of pH, ionic strength, and surface charge density on the adsorption of simple proteins to interfaces with polymeric films present
  • Adsorption of polysoaps to liquid/liquid, liquid/air, and liquid/solid interfaces
  • Development of p-chem experiments that explore interfacial phenomena
