School of Engineering Sciences in Chemistry, Biotechnology and Health at KTH

The Division of Applied Physical Chemistry at the Department of Chemistry is now looking for a Postdoc who will work together with Prof. Mats Jonsson.
The position is located at the School of Chemistry, Biotechnology and Health (CBH) at KTH.

Job description

The radionuclides 79Se, 93Mo and 99Tc will be present in the Final Repository for Short-lived Radioactive Waste (SFR) in Sweden. The main barrier material in SFR is concrete and to assess the mobility of Se, Tc and Mo in repository environments (for an assessment of post-closure safety) it is important to be able to quantify and understand their sorption to cement. This project concerns studying the sorption of Se, Tc and Mo onto cement and simpler model materials with the aim to collect data for modelling the  mobility of Se, Tc and Mo in repository environments and to develop an increased fundamental understanding of the sorption process. The work includes the design and experimental study of simple model systems as well as more applied studies. The postdoctoral researcher should have extensive experience in laboratory work. Complementary computational studies will be performed in parallel by another researcher. The postdoc is expected to be able to work both independently and together with colleagues at KTH and at other universities.

This position is a full-time position for two years. Start date is open for discussion, but we would like to see the position filled as soon as possible. The project is funded by the Swedish Nuclear Fuel and Waste Management Company (SKB). The postdoctoral researcher will participate in regular meetings with SKB.

What we offer

  • A position at a leading technical university that generates knowledge and skills for a sustainable future
  • Engaged and ambitious colleagues along with a creative, international and dynamic working environment
  • Work in Stockholm, in close proximity to nature
  • Help to relocate and be settled in Sweden and at KTH
