CURRENT CLINICAL INTERESTS
Benign red blood cell disorders, iron metabolism (including iron
deficiency and hereditary hemochromatosis), acquired aplastic anemia,
congenital marrow failure syndromes (including Diamond-Blackfan anemia
and Dyskeratosis Congenita) and the transition of care between
pediatric and adult hematologists, neurovisceral porphyrias
CURRENT RESEARCH INTERESTS
Normal and ineffective erythropoiesis, systemic and cellular iron homeostasis, and the clinical presentation and molecular underpinnings of inherited marrow failure.
The Keel Laboratory aims to understand normal and abnormal red blood cell development. Current work examines the molecular and cellular events in late-stage erythroid maturation and in particular the mechanisms that coordinate heme synthesis, iron availability, erythropoietin response, and cellular metabolism. A second project in the lab centers on inherited bone marrow failure and inherited myelodysplastic syndromes and aims to define their clinical phenotypes, natural histories, and underlying genetics to improve diagnostic accuracy and clinical care.
