Research Synopsis
Research Interests: My work focuses on understanding the pathomechanisms underpinning pulmonary arterial hypertension. Beyond pure vasoconstriction, this is a disease of profound immune dysfunction, irreversible vascular remodeling, and metabolic change. Using an integrated platform consisting of patient-derived tissue, animal models, and primary cell culture, we seek to understand (a) how the environment present in pulmonary hypertension primes the immune system, and (b) how the immune system causes chronic vascular damage in order to manifest the disease. Specifically, we examine various modes of cell death (apoptosis, necrosis, pyroptosis) in the development of PH, and how such cell damage then activates both the innate and adaptive immune systems. We then investigate how this immunological milieu contributes to the physiology and vascular lesions seen in patients with PH. We hope to use this knowledge to design and test novel strategies for treating this devastating disease.
