Job description

Organic radicals are key reaction intermediates in many chemical systems, such as the biochemistry of living organisms, organic synthesis and polymerisation, combustion systems, and the natural environment. But their detection is challenging, especially at the individual level, i.e. distinguishing between radicals with different organic structures. The European Research Council (ERC) Advanced project EPHEMERAL focuses on using real-time mass spectrometry (MS), such as Proton Transfer Mass Spectrometry (Ptr-MS), to detect individual organic radicals in the gas, in particular in the real atmosphere. We are seeking an outstanding candidate for a postdoctoral position on this project.

The position will involve some development and characterization (calibration …) of the instruments, performing experiments in gas-phase reactors in laboratory as well as measurements in the real atmosphere, and taking part in the deployment of the instrument in field campaigns. This position will be in the team of Prof. Nozière at the Department of Chemistry.

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

We are looking for candidates that have:

  • A PhD degree or an equivalent foreign degree in Chemistry, Physics, or other appropriate field. This eligibility requirement must be met no later than the time the employment decision is made.
  • A background in chemical ionization mass spectrometry, preferably Proton Transfer Mass Spectrometry (Ptr-MS), Time-of-Flight mass spectrometry, chemical ionization, or related fields.
  • Solid experience with gas-phase flow systems and reactors, as well as solid experience with operating standalone mass spectrometers (i.e. not connected to a chromatograph) such as Proton Transfer Mass Spectrometers (Ptr-MS), Chemical Ionization Mass Spectrometers (CIMS).
  • Proven research abilities (in experimental science).
  • Excellent written and oral communication skills in English, since this is required in the daily work.

Preferred qualifications

  • A PhD 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.
  • Teaching abilities and awareness of diversity and equal opportunity issues, with specific focus on gender equality.

Personal competency

As a person, you have strong problem-solving skills. You are also self-motivated, detail- and goal-oriented. Moreover, you are able to work both independently and cooperatively with a team.

Great emphasis will be placed on personal skills.

Trade union representatives

You will find contact information to trade union representatives at KTH's webbpage.

To apply for the position

Log into KTH's recruitment system in order to apply for this position. You are the main responsible to ensure that your application is complete according to the ad.

Applicants should submit:

  • A curriculum vitae
  • A copy of their PhD diploma or equivalent, translated into English or Swedish if the original document is not in these languages
  • List of publications
  • A brief cover letter (max 2 pages) explaining your motivations for the position, scientific interests and future goals.
  • In addition, three letters of reference should be sent directly to Prof. Nozière.

Your complete application must be received at KTH no later than the last day of application, midnight CET/CEST (Central European Time/Central European Summer Time).

About the employment

The position offered is for, at the most, two years.

A position as a postdoctoral fellow is a time-limited qualified appointment focusing mainly on research, intended as a first career step after a dissertation.


The position may include security-sensitive activities. To become authorized, you therefore need to pass a security check.

Striving towards gender equality, diversity and equal conditions is both a question of quality for KTH and a given part of our values.
