Your primary task is to offer statistical support to the European Society for Blood and Marrow Transplantation (EBMT). Your statistical input will contribute to scientific output (publications, international conference abstracts, presentations and posters) in the field of Haematopoietic Stem Cell transplantation and Cell / Gene Therapy.

You will be closely involved in the set-up of retrospective studies and non-interventional prospective studies. Your input is not only requested in the design and analysis, but also in the interpretation of the final results. Creating reports for the clinical investigators and contributing to manuscript writing belong to your tasks as well. The data used in the studies are most often extracted from the EBMT registry. Based on indication or topic, the studies are conducted within one of the 10 EBMT Working Parties. Further you will contribute actively to activities of the Statistical Committee of the EBMT and work closely with the Clinical Research Director, Study coordinators of the Data Office and other EBMT statisticians based in Leiden. You will be supervised by staff members of the department of Biomedical Data Sciences of Leiden University Medical Center.

You have a PhD or Master degree in statistics or (bio) statistics or a related field. You have broad experience in statistical analysis in general and are able to deliver accurate statistical reports generated by reproducible statistical code. You will work with survival analysis in particular (advanced Cox models, competing risks, frailty models, etc). You have an active knowledge of SPSS, R and Microsoft Office. Given the setting of international collaboration with medical researchers, study coordinators, data managers and statisticians, fluency in English and Dutch are important, as well as excellent communication and collaboration skills. You are a multi- tasker who can operate in a dynamic and deadline-driven environment. You should be willing to make short travels within Europe.

You will be employed on the basis of a 28-36 hours week. The appointment starts with one year and has the possibility of extension to a permanent contract. We invest heavily in education and training of our staff.

Your salary will be max € 4361 gross per month based on a full time position, depending on your qualifications and experiences. You will receive an 8% holiday remuneration, a year- end bonus, a pension arrangement with the National Civil Pension Fund, and you may join our collective health insurance policy.

European Society for Blood and Marrow Transplantation (EBMT) is a non-profit organisation, which was established in 1974 to allow scientists and physicians involved in blood and marrow transplantation to share their experience and develop co-operative studies. Our mission is to foster excellence in science in order to further improve the outcomes of stem cell transplantation and inform all concerned, including patients and their families, about developments in the field.

To this end, the Society works to the highest standards to promote all aspects associated with the transplantation of haematopoietic stem cells from all donor sources and donor types including basic and clinical research, education, standardisation, quality control, and accreditation for transplant procedures. Members of the EBMT are mainly centres active in transplantation of any kind of haematopoietic stem cells or any other organisation or individual involved in the care of donors and recipients of haematopoietic stem cells.

The EBMT has offices in Barcelona, Leiden, London and Paris, and currently has 70 members of staff working on behalf of the organisation. You will be supervised by staff members of the department of Biomedical Data Sciences of Leiden University Medical Center, which has a large and active group dedicated to survival analysis and an intensive collaboration with several organisations active in the field of haematopoietic stem cell transplantation. The department and EBMT have a close collaboration, both in statistics and data management, for more than 40 years.
