Personal profile

Description of research and teaching

My research interests cover a wide area ranging from biomaterials, photo-activated molecules and nanoparticles (drug/metallic) to drug release and release modeling.

Recently I’ve been most interested in

  • Photon upconversion, using light as a tool for studying and controlling nanosystems
  • Controlling the adhesion, permeation and drug release from drug nanoparticles and drug loaded matrices.
  • Utilization of nanofibrillar cellulose in drug release applications.
  • Release modelling from drug (nano)formulations.
