    Promote Scientific Knowledge & Organize Scientific Workshops

    The IFRS functions principally to promote scientific knowledge on fibrinogen and organize the International Fibrinogen Workshops which meet in alternate years. The meetings are open to all investigators and scientists including physicians with a clinical or basic research interest in fibrinogen. These colloquia provide a forum for collegial presentations and discussions of new findings and perspectives. Many collaborations and friendships have been kindled at previous Workshops, and our goal is to continue this tradition. Members of the IFRS receive reduced registration fees for the Workshop, a reduced subscription rate for Blood Coagulation and Fibrinolysis (BC&F). The IFRS Constitution, which was revised in 2010, is available here.

    Growing the Community of Scientists

    Annual dues for regular members are $40. An optional subscription to Blood Coagulation and Fibrinolysis is $401.00 (total for membership and subscription is $441.00). Students can join at a nominal fee of $1 with a written statement of status by their research advisor (email to Marlien.Pieters@nwu.ac.za).

    27th International Fibrinogen Workshop, June 2-6, 2024

    Esbjerg, Denmark


    The previous workshop was a huge success:

    26th International Fibrinogen Workshop

    In-person workshop, June 12-16, 2022

    Jongny sur Vevey (Switzerland)

    Free online mini-symposium, June 15 & 16, 2021

    Dear friends,

    With travel restrictions still in place and the uncertainty on the evolution of the Covid-19 pandemic for the next few months, we made the decision to postpone the in-person IFRS Fibrinogen Workshop until June, 12-16, 2022.

    These workshops are unique opportunities to share new advances and ideas, and a great occasion to meet the people doing state-of-the-art research in the field in a dynamic and friendly atmosphere. This special aspect of the workshop cannot be replaced by an online meeting. However, we feel that it is important to share and discuss the most recent research on Fibrinogen and Factor XIII. We are pleased to announce a free, online mini-symposium, which will be held in the afternoons of Tuesday, June 15th and Wednesday, June 16th, 2021.

    Registration for this free meeting is required is available on the workshop website: https://www.unige.ch/medecine/IFRS2020/

    Abstract submission is open on this website. The deadline for the online symposium is March 15th, 2021. All abstracts already submitted for the Vevey workshop will automatically be reviewed for the online symposium. In addition, all paid registration fees for the full workshop package will remain valid for the postponed meeting.

    We look forward to your abstracts and hearing about your exciting new research in June.
