POSTDOCTORAL RESEARCHER

Scientific context

IMMENs 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. In this context, Vaahtomeri laboratory addresses fundamental cell and vascular biology mechanisms of cell migration/interactions

Who are we looking for

We are looking for candidates with a strong background in life sciences (for example, cell biology, vascular biology, immunology biochemistry, mouse models, or image analysis). The candidate should be highly motivated to investigate key open questions in the fields of:

• Cell Biology
• Vascular biology
• Immunology

At the postdoctoral level, the candidate should have a PhD degree in appropriate biological or medical subject and a demonstrated strong track record of peer-reviewed publications. Previous experience in cell biology, vascular biology, mouse models, immunology or high-end imaging approaches is considered an advantage. The degree requirement must be met by the beginning of the employment. 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 position is for a fixed-term (2 years) and includes a six-month trial period and a possibility for extension upon success in postdoctoral research. The position will be filled immediately upon identification of a suitable candidate. 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 Dr. Kari Vaahtomeri and takes place in the context of the active research community of IMMENs groups. The research group has prominent international connections and is 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.
