His career has focused on translational research in hemoglobinopathies to answer therapeutic questions in hematologic and iron overload disorders. He has been a federally-funded research investigator for over 30 years and been national principal investigator for many successful trials -- including transfusion therapy and chelation therapy in hemoglobinopathies. He has been principal investigator or co-investigator on many of the key translational studies, including understanding the mechanism and treatment of neurologic injury in sickle cell disease; iron trafficking and iron overload in hemoglobinopathies, and new therapies to change the pathophysiology of sickle cell biology. He has served as Editor-in-Chief of Pediatric Hematology and Oncology; Chairman of the Thalassemia Clinical Research Network, and Director of the Cooley’s Medical Board. Dr. Vichinsky has published over 300 articles and several books, and has received lifetime achievement awards from the Cooley’s Anemia Foundation and the National Sickle Cell Disease Association.
Ashutosh Lal, MD:
Director, Thalassemia Clinical Program
Dr. Lal organizes the day-to-day management of patients attending our Comprehensive Thalassemia Center, and supervises the clinical program. The Center's major focus is health maintenance of transfusion-dependent patients by rigorous monitoring of clinical indicators, such as iron burden, cardiac function, endocrine testing, growth and nutrition. In order to improve coordination of care for our patients living outside California, we are designing innovative methods to communicate with their providers. Dr. Lal's research areas are the natural history of hemoglobin H disease, developing intensive iron chelation regimens, and nutritional deficiencies in thalassemia. Simultaneously, in the laboratory he and his team are trying to define whether iron-induced injury to mitochondria can help to explain organ damage in thalassemia.

Sylvia Titi Singer, MD:
Over the past decade, Dr. Singer has been primarily involved in the clinical care of thalassemia patients and has conducted thalassemia-related research. Beyond the opportunity to care for these special patients, the involvement in their treatment has also stimulated her interest in clinical and translational research. She has been involved in research investigating drug stimulation of fetal hemoglobin with hydroxyurea, butyrate and erythropoietin, in attempts to increase the hemoglobin in non-transfused patients. She developed a study aimed at understanding the risk factors and causes for pulmonary hypertension in thalassemia. More recently, her study centers on investigating the progress, laboratory assessment and potential prevention of reduced fertility in adolescents and adult regularly-transfused thalassemia patients.
Carolyn Hoppe, MD:
Director, Hemoglobinopathy Diagnostic Lab
Dr. Hoppe is a hematologist/oncologist at CHO and a clinical scientist at CHORI with a focus in translational research in sickle cell disease.

Marcela Weyhmiller, PhD:
Marcela Weyhmiller received her BSc from UC Berkeley and PhD from the University of Washington in Materials Science Engineering where her thesis focused on the magnetic properties of iron oxide nanoparticles. Her expertise in iron and magnetism brought her to Children’s Hospital Oakland in 2009 where her work focuses on iron overload. As the Coordinator for the SQUID-Ferritometer Program she measures liver iron concentration (LIC) using the SQUID. SQUID is a safe, painless, quick and non-invasive technique that utilizes a superconducting magnetic sensor to measure “how magnetic” the liver is. LIC is used as an indicator of total body iron stores and this information helps the Thalassemia team manage the transfusion and chelation care for our patients. In addition Marcela works on the Multi-Center Study of Iron Overload - an international collaboration to study the underlaying mechanisms controlling iron deposition and overload in Thalassemia, Sickle Cell Anemia and Diamond Blackfan Anemia.
