Global Thrombosis Forum
The Global Thrombosis Forum(formerly Georgia Thrombosis Forum) has continued to develop innovative approaches to further education and research programs worldwide. In the past eleven years, consistent with the North American Thrombosis Forum’s objectives, training, and educational initiatives, the Global Thrombosis Forum, under the leadership of Dr. Atul Laddu, has made a major impact in inspiring public sectors. In particular, GTF has been focusing on younger students to promote awareness of thrombosis and its management at various levels. Such programs have recruited talented younger scholars who have participated in educational and translational research programs and public advocacy in an exemplary fashion. Under the strong leadership of Dr. Sam Goldhaber, President of the NATF, and Dr. Atul Laddu, President and CEO of GTF, these projects will continue to expand and will provide opportunities for younger students which will be helpful in their career planning and education to become physicians and scientists to serve healthcare and biomedical research programs.
GTF also has a close partnership with IUA on these programs. One of the major efforts and educational programs is organizing scientific symposia and meetings. For this reason, GTF and the North American Chapter of the IUA have planned annual symposia on select topics.
