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.

We are looking for a PhD candidate to join our team Genetic Modification of NK cells for Optimized Functions against Cancer. 

The research group

The group Genetic Modification of NK cells for Optimized Functions against Cancer within the Cell&Gene Therapy group  is part of the Center for Hematology and Regenerative Medicine (HERM) at Department of Medicine, Huddinge and the Competence Center for next-generation NK cell-based therapies. The Department of Medicine at Huddinge comprises five units, six core facilities and, around 80 independent research groups. The Center for Hematology and Regenerative Medicine (HERM) is a research unit within the Department of Medicine Huddinge which brings together basic and clinical research competences to pursue cutting-edge research improving the understanding of mechanisms involved in normal and malignant hematopoiesis.

The doctoral student project and the duties of the doctoral student

The doctoral project focuses on advancing NK cell-based immunotherapies through genetic engineering and functional characterization. The student will develop and optimize strategies using cutting-edge techniques such as CRISPR/Cas9 gene editing, lentiviral vector production and characterization, transduction and transfection of cell lines and primary cells, flow cytometry, primary cell culture, and a broad range of molecular and biochemical assays, including relevant techniques for functional and mechanistic studies. The project aims to explore novel approaches to enhance NK cell function for therapeutic applications in hematological malignancies.

As a doctoral student, you will be responsible for planning, performing, and analyzing experiments, manage common laboratory reagents, and maintain accurate experimental records. While you will contribute to ongoing projects in the laboratory, you will also under guidance develop and lead your own research project within the scope of NK cell immunotherapy. The doctoral education also includes writing scientific manuscripts and presenting research results in both national and international contexts. The position offers the opportunity to collaborate closely with experienced researchers in a dynamic and interdisciplinary environment, combining molecular biology, immunology, and translational research.

What do we offer?

A creative and inspiring environment full of expertise and curiosity. Karolinska Institutet is one of the world's leading medical universities.

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.
