Carl Tryggers postdoctoral fellowship available

A two-year Carl Tryggers Postdoctoral Fellowship is now available to work on supergene evolution in the Slotte lab at Stockholm University.

Project overview

Supergenes are sets of loci that can maintain adaptive combinations of traits, because they are inherited as a unit. They are responsible for a wide range of balanced polymorphisms in nature, yet our understanding of their origin and evolution remains incomplete. Distyly is a balanced floral polymorphism that has attracted the attention of many generations of biologists, including Darwin. In this project, we aim to study molecular evolution of the distyly supergene in Linum (wild flaxseed species), a plant system that is ideal for this purpose.


The successful applicant will lead and conduct evolutionary genomic analyses with particular focus on patterns of molecular evolution at the distyly supergene and comparative genomic analyses to pinpoint the role of structural variation for recombination suppression. For this purpose, the postdoc will be able to draw on high-quality genome assemblies of several Linum species as well as population genomic and expression data generated as part of the ERC-funded project SuperGenE.

Applicants are required to hold a PhD, preferably in evolutionary genetics, population genetics, comparative genomics, bioinformatics, or related topics. The candidate should have proven experience in genomic analyses with an evolutionary genetic focus and very good writing skills. Candidates should be able to work independently, as well as together with team members, and exhibit drive and motivation for the research task. Excellent proficiency in English (the working language of the group) is required.

The position is for two years, funded by a stipend from the Carl Tryggers foundation. Ideally we are looking for a candidate who can start in the spring of 2022, but the starting date can be discussed. According to the rules of the Tryggers foundation, the PhD degree must be less than six years old, and applicants must receive final approval by the foundation.


To apply for the Carl Tryggers postdoctoral stipend, please send a pdf with the following directly to Dr. Tanja Slotte (tanja.slotte@su.se), in an email with the subject header ”Carl Tryggers postdoc 2022”:

  1. A cover letter describing why you are interested in the project and position and what makes you suitable for the project.
  2. A CV, including contact details and personal data, and contact information for 2-3 reference persons and a list of publications.
  3. A copy of your PhD diploma (if you have not yet defended, you can still apply, but please include a letter from your supervisor indicating your planned PhD defense date in that case).

The fellowship will remain open until filled, but we will start processing applications on January 17th 2022, so please send your application before this date to ensure full consideration.

For informal questions about this fellowship, please contact Dr. Tanja Slotte directly at tanja.slotte@su.se.

General information on opportunities for PhD students and post-docs

If you find our research topics interesting and would like to join the lab, you are welcome to contact Tanja Slotte directly. For prospective postdocs, there is an opportunity to apply for a postdoctoral fellowship from the Wenner-Gren foundation (deadline in October) and from the Carl Tryggers foundation (deadline in May) every year. Other funding sources for postdocs include EMBO LTF fellowships (evaluated twice a year) and Marie-Curie fellowships. PhD student positions will be officially announced through Stockholm University.

Undergraduate students and master students

If you are interested in evolutionary genomics and want to develop your skills in population genetic analyses, then we may have a project for you! Please contact Tanja Slotte if you find our research interesting and would like to discuss opportunities for a Master/degree project.
