Research Interest Summary

Our basic science and translational research group studies the molecular mechanisms of pulmonary vascular disease and pulmonary hypertension using network-based bioinformatics with unique experimental reagents.

Research Interests

I am a physician-scientist and cardiologist who leads a basic and translational research program and clinical center investigating the mechanisms of pulmonary hypertension (PH) and endothelial biology. More recently, our lab has been studying the mechanisms by which the heart-lung-brain axis communicates in health and disease. To do so, we use computational theory to study gene network architecture and couple these insights with unique experimental reagents derived from genetically altered rodent and human subjects. By combining in silico network biology approaches with in vivo mechanistic discovery, our lab has defined the systems-level functions of non-coding RNAs and downstream pathways controlling metabolism, mechanosignaling, and inflammation as root causes of vascular disease and pulmonary hypertension (PH). These findings have led to new methods implemented to identify persons at-risk for PH and to the development of new molecular therapies targeting these pathogenic causes. This work is also the cornerstone of evolving applications of network theory to the discovery of RNA-based origins of human diseases, in general.
