About us

We are the Department of Chemical and Pharmaceutical Engineering at Sofia University “St. Kliment Ohridski”. Our research covers surfactants, foams, emulsions and dispersions, with applications in chemical, pharmaceutical and food systems. We work with academic and industrial partners to understand how these systems behave and to address practical research challenges.

Main research areas

  • Surfactant aggregates and mesophases in bulk: structure, rheology, stability
  • Multiphase systems (foams, emulsions): formation, stability, rheology
  • Complex mixtures: surfactants + polymers/particles/perfumes/cosurfactants – interactions on bulk and on interfaces; natural surfactants
  • Enzyme-surfactant mixtures: competitive adsorption, product solubilization, denaturing in concentrates
  • Biophysics & colloid science in fat digestion and drug delivery systems
  • Surfactant adsorption: thermodynamics, kinetics, surface rheology
  • Physicochemical theoretical models: adsorption, aggregation, rheology, etc.
  • Atomistic molecular dynamics simulations: aggregation, adsorption, …

Research and Collaborations

At DCPE, our research in disperse systems drives innovation across the chemical, pharmaceutical, and food industries. We partner with world-renowned institutions such as Cambridge University, ETH Zürich, the Max Planck Institute for Polymer Research, ESPCI-Paris, Technion, and the Hebrew University of Jerusalem. Our industrial collaborations include global leaders like Unilever, Janssen, BASF, Saint-Gobain, PepsiCo, Kraft Foods, and Colgate-Palmolive. With over 20 active international projects, DCPE stands at the forefront of cutting-edge science and industry impact.
