Nina Kovalchuk is a Research Fellow working on EPSRC funded MEMPHIS (Multi-scale Exploration of MultiPhase Physics In FlowS) program. 

Nina published over 60 research papers in scientific journals as well as book chapters in the field of adsorption dynamics and the effect of surfactants on multiphase flows (instabilities due to surfactant transfer, surfactant enhanced spreading and superspreading, formation and coalescence of drops on macroscale and in microfluidic devices), stability and dynamics of foams, suspensions and emulsions. She also gives conference and invited talks on the above subjects

Research

Research Themes

  • kinetics of liquid bridges and drop formation in the presence of soluble surfactants on mm scale and in microfluidics;
  • wetting, spreading and evaporation of liquids on various substrates;
  • interfacial layers, dynamics of adsorption and interfacial rheology;
  • foams: formation, drainage, interaction with substrates;
  • rheology of complex liquids;
  • molecular recognition;
  • self-organization in multiphase liquid systems far from equilibrium containing surfactants.
