Research interests

  • Micro- and Nanoscale flow phenomena and boundary conditions (electrohydrodynamic effects,

structure formation, effects of confined geometries)

  • Hydrodynamics (Effects of hydrodynamic interactions and hydrodynamic screening)
  • Polyelectrolyte/Polymer/Colloidal Dynamics in dilute and dense solution and confined

geometries

  • Coupling of electrostatic and hydrodynamic effects
  • Properties of charged matter in presence of explicit ions
  • Properties of polymer brushes (protein repellency, wettability)
  • Driven systems under strong non-equilibrium conditions
  • Flow characteristics around rotating micromotors (synchronization effects, hydrodynamic

interactions)

  • Properties of solvent/solute interactions (hydrophobic and hydrodynamic

interactions)

  • Characteristics of specific DNA structures like the DNA i-motif and the G-quadruplex
  • General theory of molecular folding mechanisms (Hidden complexity, solvent properties,

free energy landscapes, rare events)

  • Lipid bilayers: Interfacial behavior of water and interactions with compatible solutes
  • Influence of osmolytes on proteins and membranes in aqueous solutions (structural

ordering of water, solubility)

  • Thermodynamics, non-equilibrium effects, kinetics, general description of systems in the

the framework of statistical mechanics

  • Method development (free energy landscapes, mesoscopic simulation methods,

microchannel boundary conditions)

  • QM/MM simulations of osmolyte-solute interactions and cytosine-rich DNA strands
