Research Interests

  • The clinical impact of inherited bleeding disorders including disease prevalence of quantitative assessments of bleeding
  • The use of bleeding scores as a screening tool for inherited bleeding disorders and to assess disease severity
  • The underlying pathophysiology of inherited bleeding disorders at a cellular and molecular level

 Current Models

  • BOEC (Blood Outgrowth Endothelial Cells)

 Active/Future Studies

  • The use of BOEC to understand angiodysplasia in von Willebrand disease (VWD) and to investigate potential novel treatments
  • A national study evaluating abnormal bleeding in female carriers of hemophilia
  • Identification of undiagnosed individuals affected with an inherited bleeding disorder using a social media campaign
