Project description

We seek to appoint a postdoctoral fellow with expertise in high-resolution mass spectrometry (HRMS) analysis and exploration of nontarget mass spectrometry datasets. The successful applicant will contribute in projects where HRMS-based DNA- and RNA-adductomes in human and animal samples are profiled as a means of exposure diagnostics and to discover new biomarkers of adverse effects (e.g., reproductive aberrations and mental illness).

Main responsibilities

You will be responsible for the high-resolution mass spectrometry analysis of adducts, with particular focus on chemical modifications of DNA and RNA. This includes performing HRMS/MS experiments on LC-Orbitrap and associated data processing for adductomics. Method optimization as needed and application of the adductomics technology in human and wildlife samples will be part of the research activities. Other responsibilities include presentation of the research findings at conferences, publishing and communication.

Qualification requirements

In order to qualify for a Postdoctoral position, applicants are required to hold a Swedish doctoral degree or an equivalent relevant degree from another country. The degree must have been completed no later than when the employment decision is made.

Assessment criteria

It is considered an advantage if the doctoral degree or an equivalent degree was completed no more than three years prior to the application deadline. Under special circumstances, an older degree may also be an advantage. Special circumstances refer to sick leave, parental leave, elected positions in trade unions, service in the total defense, or other similar circumstances, as well as clinical attachment or service/assignments relevant to the subject area.

In the appointment process, special attention will be given to research skills and your ability to successfully complete the project. Your doctoral degree should be in analytical chemistry or a field closely related to the project. Skills in a high-resolution mass spectrometry based -omics technique and data analysis are desirable. The candidate should have a high level of written and spoken English language skill as well as the ability to work in a team.

About the employment

The position involves full-time employment for a minimum of two years and a maximum of three years, with the possibility of extension under special circumstances. Start date 2026-03-01 or as per agreement.
