Research Interests
Our exquisitely fundamental reasearch work focuses on understanding how fluids behave at interfaces (solid-liquid, liquid-gas, and liquid-liquid) to enable practical applications.
The subjects of our studies include aqueous electrolyte solutions (towards enhancing ion-exchange processes employed, e.g., in nuclear-waste-site remediation), carbon nanotubes and graphene sheets (can we stabilize dispersions of these nanoparticles? How do they interact with phospholipid bilayers?), adsorption and self-assembly of amphiphilic molecules (how does confinement affect the structure of self-aseembled surfactant aggregates?), heat transfer in nanocomposite materials (would you like your laptop not to heat up?), and the characterization of heterogeneous catalysts (how can we obtain 100% product selectivity?).
Our projects require an inter-disciplinary approach in which accurate experimental results are coupled to state-of-the-art computational and theoretical investigations. Our laboratory (see facilities) is equipped with one cluster of dual-processor nodes, hotohke, and by one ensemble of experimental equipment suitable for the study of surface phenomena. We developed significant expertise in conducting classical Monte Carlo and molecular dynamics simulations. We are extending our capabilities to include ab initio methods and integral equations. When the experiments required to validate our theoretical predictions cannot be accomplished with our facilities, we rely on experienced collaborators with whom we have established a fruitful intellectual exchange of ideas, problems, and solutions.
