I have been interested in the cognitive outcomes in adult survivors of childhood cancer. In particular, I am studying individuals who were treated for leukemia as children or adolescents. I have primarily focused on neuropsychological measures in this particular study. I am also involved in a study assessing cognitive outcomes in adults who have been treated with chemotherapy and bone marrow transplants for treatment of CML. We have been following individuals prospectively with psychological questionnaires and neuropsychological measures.
