Postdoctoral Researcher, Centre of Excellence in Immune – Endothelial Interfaces (IMMENs)
The newly established Finnish Centre of Excellence in Immune – Endothelial Interfaces (IMMENs) invites applications for two fixed-term (2-years) positions of Postdoctoral Researcher. The successful candidates will work in the research groups of Dr. Taija Mäkinen and Dr. Kari Vaahtomeri at the Faculty of Medicine, University of Helsinki.
Scientific context
IMMENs, composed of research groups at the University of Helsinki (director Dr. Taija Mäkinen and Dr. Kari Vaahtomeri) and Åbo Akademi University in Turku (Dr. Cecilia Sahlgren and Dr. Guillaume Jacquemet), investigates the role of lymphatic vessel endothelium in controlling immune responses. Current evidence shows that much of immune regulation occurs locally at the site of inflammation. Recent studies have revealed important crosstalk between lymphatic endothelium and immune cells, resulting in phenotypic changes that control immune cell trafficking, fate and function. IMMENs will develop novel experimental approaches to uncover the mechanisms and therapeutic potential of lymphatic endothelial immunomodulation in homeostasis, inflammation and tumorigenesis using in vivo genetic mouse models, advanced live and intravital imaging, engineered microchip models, primary cell co-culture systems and novel microscopy and analysis methods. The research will provide foundation for translational studies aimed at more effective therapies for precise modulation of immune responses.
Who are we looking for
We are looking for candidates with a strong background in life sciences (for example, cell biology, biochemistry, mouse models, and/or image analysis). The candidate should be highly motivated to investigate key open questions in the fields of:
- Vascular biology
- Immunology
- Cell Biology
At the postdoctoral level, the candidate should have a PhD degree in appropriate biological or medical subject. The PhD degree must have been obtained no more than three years prior to the application deadline. The three year period can be extended due to circumstances such as sick leave or parental leave. Previous experience in cell biology, vascular biology, mouse models, immunology or high-end imaging approaches is considered an advantage. Candidates should be able to demonstrate abstract thinking as well as the potential to develop and pursue scientific projects in the fields relevant for this call. Furthermore, the candidate should have excellent communication skills in English and the ability to work in an international environment.
What we offer
The initial appointment is for 2 years and includes a possibility for extension. The position will be filled immediately upon identification of suitable candidates. The starting date is negotiable. Salary will be commensurate with qualifications and experience based on the University of Helsinki guidelines. The chosen applicant is expected to reside in Finland while employed by the University of Helsinki.
The work is supervised by one of the UH principal investigators at IMMENs (Dr. Taija Mäkinen, Dr. Kari Vaahtomeri and takes place in the context of the active research community of IMMENs groups. Our research groups have prominent international connections and are located at the medical campuses in the University of Helsinki. The immediate research environment provides state-of-the-art facilities, cutting-edge expertise in vascular-, tumor-, immunological- and stem cell biology, and great synergy with renowned research groups.
