Mettine Bos elected as Vice Chair of the European Thrombosis and Haemostasis Alliance (ETHA)

BRUSSELS, BELGIUM, 9 May 2023 — The European Thrombosis and Haemostasis Alliance (ETHA), initiated and supported by the International Society on Thrombosis and Haemostasis (ISTH), is pleased to announce the election of Mettine Bos, Ph.D., as vice chair of the organisation for a term of two years.

Bos is an Assistant Professor at the Leiden University Medical Center in The Netherlands. As the Vice Chair of ETHA, Bos will work closely with the Chair Ingrid Pabinger-Fasching, Ph.D., and Alliance members to further the mission to bring awareness to thrombosis and hemostasis as a critical global patient safety issue.

Formed in 2018, the ETHA was created to advocate for better awareness and prioritisation of thrombosis and hemostasis in European Union (EU) patient safety and research programmes. The ETHA, comprised of 26 related national societies, has a united focus to work with the public and decision-makers to share expertise in clotting and bleeding disorders, elevate patient-centric policies and promote improved outcomes in the EU.

"My appointment as the vice chair of ETHA is a great opportunity to collaborate with esteemed experts in the thrombosis and hemostasis community to advance research and prevention efforts across Europe," said Bos. "Building upon the accomplishments of the Alliance is an honor, and I am confident that by working together we will continue to make significant strides towards ETHA's mission of improving patient care and advancing research. I am eager to work alongside our chair and colleagues to make a meaningful impact on the lives of patients and their families."

Bos completed her graduate work at the Department of Plasma Proteins at Sanquin Research (Amsterdam, The Netherlands) and postdoctoral fellowship in the Camire Lab at the Children’s Hospital of Philadelphia (U.S.). As Principal Investigator at the Einthoven Laboratory for Vascular and Regenerative Medicine in Leiden, The Netherlands, her research focuses on structure-function aspects of blood coagulation proteins, with the overall goal of engineering innovative therapeutic proteins or identifying novel targets for the treatment of either bleeding or thrombosis. Bos previously developed a novel procoagulant protein that is currently in clinical development as a reversal agent to restore hemostasis in patients taking factor Xa inhibitors.

"We are delighted to announce that Bos, an accomplished researcher and expert in the field of thrombosis and hemostasis, has joined ETHA as the vice chair," said Chair Pabinger-Fasching. "With her extensive background in both basic and translational research, she is the ideal candidate to help guide ETHA's efforts in raising awareness, promoting research, and improving patient care across Europe. Bos has an impressive track record of leadership and has held key positions, including serving as the president of the Dutch Society for Thrombosis and Haemostasis. We look forward to working with Bos and leveraging her expertise to advance ETHA's mission."
