Dr. Klings is an Associate Professor in the Department of Medicine. She attends in the Medical Intensive Care Unit and on the Pulmonary Consultation Service at Boston Medical Center. Additionally, she has a clinic in the Pulmonary Hypertension Center at Boston Medical Center where she is involved in the diagnosis, evaluation and treatment of patients with pulmonary hypertension (Pulmonary Hypertension Center).  She has special interest in the management of patients with chronic dyspnea and is the Medical Director of the Pulmonary Rehabilitation Program.

Dr. Klings’ research since fellowship has focused on pathogenesis of pulmonary vascular complications of sickle cell disease. She is an NIH-funded Principal Investigator .in the Pulmonary Center collaborating with the Boston Comprehensive Sickle Cell Center,Sickle Cell Genetics Research group and the Cardiovascular Proteomics Center at Boston University. She has phenotypically screened close to 200 sickle cell patients at Boston Medical Center for the presence of pulmonary hypertension and has begun to study the role that genetic polymorphisms play in the pathogenesis of this disease process. Along with her collaborators at Boston University, she was instrumental in formation of the multi-center SickleGen consortium (www.bu.edu/sicklegen) which has brought together the largest cohort of prospectively collected SCD patients with well-established cardiopulmonary phenotypes for genetic studies. Known nationally as a leader in the care and treatment of patients with sickle cell disease and pulmonary hypertension, she headed a committee of 25 hematologists, pulmonologists and cardiologists to develop clinical guidelines sponsored by the American Thoracic Society for the care and treatment of these patients, which was published in 2014.
