Katja Ohenoja


Post-doctoral researcher


I am post-doctoral researcer at Fibre and Particle Engineering research group. I did my doctoral thesis about fine and ultrafine grinding of industrial minerals (2014). Since then I have worked as a responsible researcher in projects which aim to more effective utilization of industrial secondary materials, like fly ashes and slags.

Research interests

  • Utilisation of industrial sidestreams
  • Sustainable cementitious materials
  • Mechanical treatments
  • Nanoparticles
