Research Interests

Our lab is interested in the biology and genetics of age-related disease.  Specifically, we are interested in syndromes of telomere shortening which capture both the degenerative and cancer-prone phenotypes of aging.  Human syndromes associated with telomere shortening were first identified in the context of dyskeratosis congenita, a premature aging syndrome that predisposes to cancer.  Dyskeratosis congenita patients prematurely die from aplastic anemia, the prototype of stem cell failure disorders.  Mutations in the essential components of telomerase also cause progressive and fatal scarring of the lungs in idiopathic pulmonary fibrosis.  At least 10% of individuals with idiopathic pulmonary fibrosis carry mutant telomerase genes or have short telomeres.  The goal of research in our lab is to understand the genetics and pathophysiology of telomere-mediated disorders in hopes of delineating translational approaches to their treatment.
