Research work

  • Redox chemistry of actinides (U, Np, Pu) and fission products (Tc) in the presence of natural organic matter or minerals
  • Complexation of actinides with organic ligands (humic and fulvic acids, small organic molecules) and their effect on actinide sorption and transport in geological systems
  • Retention of radionuclides on clay rock, buffer material, cementitious material and oxides
  • Calixarenes as organic extraction agents for actinides and lanthanides
