My research interest is the pathobiology of pulmonary vascular diseases, particular class I and class III pulmonary hypertension. The focus in my lab is on innate immunity signaling, inflammation and endothelial progenitor cell biology. The particular emphasis is on dysregulated recognition of ribonucleic acids and Toll-like receptor 3 signaling in the pulmonary endothelium, as well as the role of primitive endothelial cell clones in the pulmonary vasculature and in pulmonary hypertension. In addition, we are interested in vascular regeneration in the lung tissue. The goal of the translational research program is to develop novel therapies for pulmonary vascular disease based on new targets that we identify in our work.
