Lea Steffes
Assistant Professor of Pediatrics (Pulmonary Medicine)
BioDr. Steffes is a pediatric pulmonologist and Assistant Professor in Pediatrics in the Division of Pulmonary Medicine at Stanford University. She has completed an advanced fellowship in Pulmonary Vascular Disease at Lucile Packard Children's Hospital Stanford. Her clinical expertise focuses on rare pediatric lung diseases, with particular specialization in heritable forms of pulmonary vascular disease and developmental lung disorders.
Dr. Steffes' research centers on understanding the cellular characteristics of occlusive neointimal lesions, the abnormal cells that obstruct pulmonary blood flow in pulmonary hypertension. Her work specifically examines the contribution of mesenchymal cell subsets to pediatric pulmonary vascular disease, delineating mechanisms within both pre- and post-capillary networks. By leveraging insights from developing human and diseased mouse lung, her research provides a mechanistic framework for understanding childhood-onset pulmonary vascular diseases with the ultimate goal of identifying novel therapeutic targets for pulmonary hypertension. -
Robert Steffner
Clinical Associate Professor, Orthopaedic Surgery
BioDr. Steffner specializes in the evaluation, diagnosis, and treatment of bone and soft tissue tumors in pediatric and adult patients. This includes primary bone and soft tissue sarcomas, locally active conditions such as giant cell tumor, aneurysmal bone cyst, and chondroblastoma, as well as impending and pathologic fractures from metastatic carcinoma, multiple myeloma, and lymphoma. He works closely with the multidisciplinary sarcoma group at the Stanford Cancer Center to provide coordinated, highly specialized treatment strategies.
Research interests include circulating tumor DNA in bone and soft tissue sarcomas, local drug delivery, establishment of a national bone and soft tissue registry, and collaborative clinical studies on imaging and soft tissue management. -
