Major Areas of Research

  • Alpha thalassemia and erythroid and non-erythroid effects of alpha globin gene variants
  • Pulmonary manifestations of sickle cell disease
  • Population and international health
  • Critical care outcomes and economic evaluations

Program Description

As a member of the Physiology Unit, Dr. Ruhl leads clinical research efforts within a translational research team focused on the impact of Alpha thalassemia on human health, including the impact of varying alpha globin gene variants on sickle cell disease and malaria.

Dr. Ruhl is the principal investigator of clinical protocols screening subjects for variations in alpha globin gene variants and collecting biospecimens in order to identify and describe the underlying changes in pathophysiology, including vascular function, based on alpha globin gene variants. Dr. Ruhl is also engaged in population health studies to evaluate potential impacts of alpha globin gene variants on several health outcome measures, including renal, cardiovascular, and pulmonary end-organ effects, in large regional and national cohort studies. Dr. Ruhl serves on the NIH Pulmonary Consult Service and routinely sees patients in the NIH Sickle Cell Program.

Biography

Dr. Ruhl attended the University of Virginia School of Medicine and completed internal medicine training in the Osler Medical Residency at the Johns Hopkins Hospital. She completed a combined fellowship in critical care medicine at the NIH Clinical Center and pulmonary medicine at the Johns Hopkins Hospital and received a master’s of health sciences from the Duke University School of Medicine.

Dr. Ruhl is active in the professional community. She serves as vice chair of the NIH Staff Clinician Council and is a member of the Staff Clinician Professional Development Working Group, which serve to support physician professional development within the NIH Intramural Research Program. She serves as the executive board member of the Metropolitan DC Thoracic Society and as co-chair of the American Thoracic Society Sickle Cell Lung Disease Interest Group.
