Kazuyo Kegan, Ph.D.

April 1, 2018

Assistant Professor
Department of Anesthesiology and Critical Care Medicine
Johns Hopkins University
Baltimore, MD

Primary Research:

The goal of Dr. Kegan’s research program is to understand the mechanisms, regulation, and functional outcomes of immune responses in the pulmonary vasculature during the development of pulmonary hypertension. She has strong expertise in vascular biology and has focused on the role of inflammatory mediators in pulmonary angiogenesis, vasculogenesis, and remodeling, particularly under hypoxic conditions.

Dr. Kegan is currently working to determine the mechanisms by which vascular injury and the subsequent immune response by macrophages contribute to disease progression in pulmonary hypertension using in vivo pathophysiology, in vitro cellular and molecular biology, and genetic and biochemical approaches. Clinical samples from patients with pulmonary hypertension also are utilized to uncover the relevant signaling pathways that might reveal new therapeutic targets. She is principal investigator of a research program with the ultimate goal of identifying new therapeutic targets to treat pulmonary hypertension.
