KTH Royal Institute of Technology, School of Engineering Sciences in Chemistry, Biotechnology and Health

Job description

We are seeking a highly-motivated candidate for a postdoctoral position on the detection of organic radicals (in particular organic peroxy, RO2) in Earth’s atmosphere using real-time Proton Transfer Mass Spectrometry (Ptr-MS), as part of the prestigious European Research Council (ERC) Advanced project EPHEMERAL. Organic radicals are key reaction intermediates in many chemical systems, such as living organism, combustion and natural environments. In particular, they play key roles in the self-cleaning capacity of Earth’s Atmosphere. But they have never been detected individually. Detecting these radicals in the atmosphere is the ambitious objective of project EPHEMERAL. The position therefore involves handling, characterizing, and troubleshooting a state-of-the-art Time-of-flight proton transfer mass spectrometer (PTr-MS,) and using it both in laboratory and in outdoor campaigns. This position will be in the group of Prof. Nozière at the Department of Chemistry of KTH Royal Institute of Technology, Stockholm, Sweden. 

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
  • Guidance on relocating and settling in KTH and in Sweden 
  • A key position in a prestigious and highly-innovative project

Qualifications

Requirements

  • A doctoral degree or an equivalent foreign degree in Chemistry, Physics, or appropriate field. This eligibility requirement must be met no later than the time the employment decision is made.
  • a solid experience with gas-phase flow systems and reactors
  • some experience with standalone mass spectrometers (i.e. not connected to a chromatograph) such as chemical ionization mass spectrometers (preferably Proton Transfer Mass Spectrometry, Ptr-MS)
  • excellent written and oral communication skills in English as this will be required in day-to-day work
  • strong problem-solving skills
  • proven research abilities (in experimental science)
  • self-motivated, detail- and goal-oriented
  • able to work both independently and cooperatively with a team

Preferred qualifications

  • A doctoral degree or an equivalent foreign degree, obtained within the last three years prior to the application deadline
  • Some knowledge of atmospheric chemistry or gas-phase kinetics is highly desirable
  • Awareness of diversity and equal opportunity issues, with specific focus on gender equality

Great emphasis will be placed on personal skills.
