Job description

Position as Postdoctoral Research Fellow available at the Department of Chemistry, Faculty of Mathematics and Natural Sciences, University of Oslo.

Starting date: 01.09.2023.

The appointment is a fulltime position and is made for a period of three (3) years.

No one can be appointed twice as a Postdoctoral fellow financed with funds from The Research Council of Norway (NFR).

We are looking for a highly motivated individual to take a leading role in the “Airborne Microplastic Detection, Origin, Transport and Global Radiative Impact” project funded by The Research Council of Norway.

The successful applicant will join the research group of Prof. Armin Wisthaler at the University of Oslo and develop a mass spectrometry-based method for the detection of airborne micro- and nanoplastics. She/he will use highly advanced instruments including a proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS) and an Orbitrap Fusion mass spectrometer for analyzing samples collected in urban and remote environments. The obtained data will be analyzed in joint work with researchers from the Norwegian Institute for Air Research (NILU). The successful candidate is expected to publish the results in chemical-analytical and environmental journals. The candidate is also expected to assist Master students with their experimental work in the laboratory.

The main purpose of a postdoctoral fellowship is to provide the candidates with enhanced skills to pursue a scientific top position within or beyond academia. To promote a strategic career path, all postdoctoral research fellows are required to submit a professional development plan no later than one month after commencement of the postdoctoral period.
