Do you want to contribute to top quality medical research?

To be a doctoral student means to devote oneself to a research project under supervision of experienced researchers and following an individual study plan. For a doctoral degree, the equivalent of four years of full-time doctoral education is required.

The research group

The Marquardt lab at Karolinska Institutet is based at the Division of Clinical Microbiology, Department of Laboratory Medicine (LabMed), and located at ANA Futura. Our research focuses on the regulation and function of human Natural Killer (NK) cells in tissues, with a particular emphasis on the lung. We aim to understand how NK cells are regulated in respiratory pathologies and to explore their therapeutic potential in lung cancer.

Our work combines access to unique human tissue samples with advanced technologies, including high-parameter flow cytometry and single-cell transcriptomics. These efforts are supported by close clinical and academic collaborations within Karolinska Institutet. The position is co-funded by NextGenNK, a Competence Center dedicated to the development of next-generation NK cell-based cancer immunotherapies, providing additional opportunities to interact with leading experts in the field.

The Department of Laboratory Medicine is an internationally recognized research environment focusing on the human immune system in infectious diseases, inflammation, and cancer. LabMed comprises six divisions and conducts research and education across a wide range of laboratory medicine disciplines, with the goal of improving human health in both the short and long term. The department maintains close collaboration with Karolinska University Hospital and integrates basic, clinical, and epidemiological research with strong teaching activities. It is also one of the largest teaching departments at Karolinska Institutet.

The doctoral student project and the duties of the doctoral student

Lung cancer remains one of the leading causes of cancer-related mortality worldwide, and patient responses to immunotherapy vary considerably. NK cells possess intrinsic tumor-killing capacity and are thought to contribute to early immune defense in tissues such as the lung. However, in solid tumors, their function is often impaired by immunosuppressive signals within the tumor microenvironment (TME).

This doctoral project aims to define how regionally adapted NK cells within the TME shape immune responses and influence tumor progression. The goal is to identify novel biomarkers and therapeutic targets to improve lung cancer treatment. The project will provide insight into immune regulation in both homeostatic and tumor settings and contribute to the development of more precise and personalized immunotherapies.

The doctoral student will work with human lung tissue from multiple sources, perform tissue processing and primary cell isolation, and conduct in vitro functional assays such as degranulation and cytokine production. The project integrates multiple advanced platforms, including multicolour flow cytometry, proteomics, metabolic profiling (SCENITH), and single-cell RNA-sequencing.

The position requires strong organizational and communication skills, as well as the ability to work both independently and as part of a team. Experimental work will be conducted in a BSL-2 laboratory environment, with strict adherence to Good Laboratory Practice (GLP).

The successful candidate will actively participate in the research environment, including group meetings, departmental seminars, and relevant national and international conferences. Responsibilities also include presenting results, contributing to manuscript preparation, participating in the supervision of junior students where appropriate, and engaging in routine lab activities. In addition, the student will complete the formal coursework required for the doctoral degree according to the regulations of Karolinska Institutet. The candidate is expected to actively contribute to the intellectual development of the project, including experimental design, data interpretation, and scientific communication.

This project is supported by an internal Karolinska Institutet KID grant and the NextGenNK Competence Center.

Eligibility requirements for doctoral education

In order to participate in the selection for a doctoral position, you must meet the following general (A) and specific (B) eligibility requirements at latest by the application deadline.

It is your responsibility to certify eligibility by following the instructions on the web page Entry requirements (eligibility) for doctoral education.

A) General eligibility requirementYou meet the general eligibility requirement for doctoral/third-cycle/PhD education if you:

1. have been awarded a second-cycle/advanced/master qualification (i.e. master degree), or
2. have satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the advanced/second-cycle/master level, or
3. have acquired substantially equivalent knowledge in some other way in Sweden or abroad.*

Follow the instructions on the web page Entry requirements (eligibility) for doctoral education.

*If you claim equivalent knowledge, follow the instructions on the web page Assessing equivalent knowledge for general eligibility for doctoral education.

B) Specific eligibility requirement

You meet the specific eligibility requirement for doctoral/third-cycle/PhD education if you:

– Show proficiency in English equivalent to the course English B/English 6 at Swedish upper secondary school.

Follow the instructions on the web page English language requirements for doctoral education.

Verification of your documents Karolinska Institutet checks the authenticity of your documents. Karolinska Institutet reserves the right to revoke admission if supporting documents are discovered to be fraudulent. Submission of false documents is a violation of Swedish law and is considered grounds for legal action.

(A) and (B) can only be certified by the documentation requirement for doctoral education.
