Job description

Postdoctoral Researcher in Molecular Host-Pathogen Interactions

Karolinska Institutet, Department of Women\u00b4s and Children\u2019s Health

Do you want to contribute to top quality medical research?

We are looking for a postdoctoral candidate that will work on macromolecular interactions during host-pathogen interactions by using advanced reconstitution methods, advanced imaging technologies and molecular dynamics simulations.

SciLifeLab and KI are excellent places to carry out basic biomedical research with clinical potential. Our lab is in the intersection of biology, chemistry, physics and engineering, aiming to reveal the molecular codes of cellular physiology and diseases. The candidate will greatly benefit from this interdisciplinary environment and unique infrastructure.

This position is for 2 years full-time employment with potential extension upon mutual agreement.

Application Deadline: 12 September 2026

Start Date: latest 1 Jan 2027

Your mission

The postdoctoral fellow will follow both experimental and computations pipelines to study how different macromolecules interact and contribute to interactions of pathogens with their hosts. The fellow will develop advanced synthetic biology tools to reconstitute host-pathogen interactions, analyse them quantitatively with advanced imaging and computationally with molecular dynamics simulations.

The project involves:

• molecular dynamics simulations (see Schahl et al, Advanced Science, 2026).
• working with virus like particles and human cells
• development of software and data analysis tools to characterize multiparametric datasets
• work in close collaboration with the other CSI:Nano lab members as well as other labs at SciLifeLab and KI

Your profile

To be eligible for employment as a postdoctoral researcher, a PhD or a foreign degree deemed to be equivalent to a Swedish PhD is required. This eligibility requirement must be fulfilled at the latest at the time of the employment decision. Completion of your doctoral degree within the last three years is considered an advantage. If there are special reasons, your degree may have been completed earlier.

• BSc and MSc in life science, natural sciences or engineering
• PhD in areas: cell and molecular biology, biomedicine, biophysics
• Strong expertise in model membrane tools and reconstitution of proteins
• Strong expertise in imaging technologies
• Strong expertise in chemical biology probes
• Strong expertise in molecular dynamics simulations
• Strong expertise in image analysis
• Independent working skills, teamwork spirit and willingness to help PhD/master students
• Programming skills are advantageous

What do we offer?

A creative and inspiring environment with wide-ranging expertise and interests. Karolinska Institutet is one of the world's leading medical universities. At Karolinska Institutet, we conduct successful medical research and hold the largest range of medical education in Sweden. At KI, you get to meet researchers working with a wide range of specialisms and methods, giving you ample opportunity to exchange knowledge and experience with the various scientific fields within medicine and health. It is the crossover collaborations, which have pushed KI to where it is today, at the forefront of global research. Several of the people you meet in healthcare are educated at KI. A close relationship with the health care providers is important for creating groundbreaking top quality education and research. Karolinska Institutet is also a state university, which entitles you to several benefits through our collective agreement.

The employees at CSI:Nano Lab come from international and interdisciplinary backgrounds, such as physics, chemistry, biomedicine, molecular biology and engineering. Our working language is English. In the lab, we advocate for diversity, equity and inclusion; promote open science and data sharing; encourage lab members to attend conferences; and foster healthy feedback culture. Moreover, the supervisor has open-door policy for meetings and brainstorming.

As a postdoctoral fellow at CSI:Nano Lab you will be given the opportunity to develop and/or apply state-of-the-art imaging methodologies to solve biological mysteries.
