Dr. Olivieri's interests in international health arise from work in Asia begun in 1996. In Sri Lanka she and her collaborators documented the range of clinical severity and complications in patients with Hemoglobin E beta thalassemia, the world's most common serious hemoglobinopathy. Over this period their research teams have stimulated community outreach, prevention programs, clinical guidelines and capacity building for thalassemia. A National Thalassemia Center was established in Sri Lanka in 2001. Dr. Olivieri is pursuing similar work in Bangladesh and continues efforts to expand an Asian Thalassemia Network with links throughout Asia.
