The Johnsen laboratory studies the role of variation of clotting factors, blood groups, and blood cell traits in disease, and the biological impact of differences between these factors in terms of bleeding diseases, blood clotting, pregnancy complications, and susceptibility to infection.
The work in Dr. Johnsen's lab has significance in blood clotting disorders that are inherited, such as von Willebrand disease and familial platelet disorders, and acquired blood-related diseases, including pregnancy-related vascular complications.
