Dennis Rosen, MD
Associate Medical Director, Sleep Disorders Program
Director, Pulmonary Function Lab
Assistant Professor of Pediatrics

Clinical interests: treatment of children with sleep-disordered breathing, and specifically those with underlying medical complexity
Research interests:  Population-specific sleep disorders in children with Down syndrome. I have written a book about physician-patient communication and the obstacles which can compromise it, and developed interactive workshops for physicians to improve outcomes through better communication with their patients.  Finally, over the last several years I have worked closely with Compañeros en Salud, the Mexican affiliate of Partners in Health. I have been going to Chiapas 1-2 times/year, mentoring and teaching young physicians doing their year of national service in rural mountain communities; teaching the Helping Babies Breathe course to the physicians and nurses; and I am hoping to co-develop a tuberculosis diagnostic and treatment program where none currently exists (once COVID recedes).

Ke Yuan, PhD
Assistant Professor of Pediatrics

Research Interest – My research focuses on defining the role of pericytes (PCs) in the pathogenesis of pulmonary arterial hypertension (PAH), a devastating disorder caused by uncontrolled proliferation of human pulmonary artery smooth muscle cells (PASMCs), which progressively occludes precapillary pulmonary arteries. It is unclear what initiates the growth of PASMCs in PAH vascular lesions. PCs are the mural cells of blood microvessels and they regulate homeostasis in the blood-brain barrier, promote tumor metastasis and function in vascular morphogenesis and development. Because of their plasticity, PCs are also known as mesenchymal stem cell-like cells and can differentiate into other cell types. Thus, our particular focus in PAH is to determine whether PCs can differentiate into vascular PASMCs.
