Dr. Herzog received her Bachelor's and MD degree from the University of North Carolina at Chapel Hill. After residency in Internal Medicine at Mount Sinai Medical Center in NY, NY, Dr. Herzog came to Yale to pursue fellowship in Pulmonary and Critical Care Medicine. During this time she also obtained her PhD in Investigative Medicine from Yale's graduate school of arts and sciences. Upon her graduation in 2005 Dr. Herzog joined faculty in the department of Internal Medicine in 2006, first as an instructor and then as assistant professor. Dr. Herzog's laboratory focuses on the relationship between chronic inflammation, neuronal guidance proteins, and lung fibrosis in a variety of fibrosing lung diseases including IPF, Scleroderma and sarcoidosis. Her unique translational approach to these diseases combines transgenic murine modeling and bioengineering with studies of primary human cells. Current areas of focus in the Herzog lab include the role of Semaphorin 7a/Plexin C1 signaling pathway in interstitial lung disease and how CD4+ T lymphocytes recruited from the blood regulate the fibrogenic phenotype of monocyte derived cells such as macrophages and fibrocytes. A third and related area involves the development of these areas as peripheral blood biomarkers of disease activity in IPF and scleroderma as well as in pulmonary sarcoidosis.
