Professional Interests:

My research focuses on the role of lung macrophages in the development of inflammatory lung diseases. Currently my laboratory is investigating the potential mechanisms of increased lung inflammation in patients with cystic fibrosis (CF) and asthma, with an emphasis on the investigation of impaired alveolar macrophage function in the patient populations.

A major focus of my laboratory is the investigation of how hypoxia impacts macrophage phenotype and function and how these changes in the immune cell may contribute to chronic inflammation in CF and asthma. We are also interested in how regional differences in immune cell function impact the regional heterogeneity of lung disease in CF. We are currently funded by the Cystic Fibrosis Foundation to investigate regional differences in the microbiome and host immune response in the CF lung.

Another area of focus involves studying the role of Angiotensin II in the development of lung inflammation in CF and asthma. There is a known polymorphism in the human angiotensin converting enzyme (ACE) gene that is associated with more severe lung inflammation. We are currently funded to investigate the mechanisms by which this polymorphism impacts disease

Biography:

Dr. Ashare received her B.S. from Vanderbilt University in 1994, her M.D. from Vanderbilt University School of Medicine in 1999, and her Ph.D. in Translational Biomedicine from the University of Iowa in 2008. Following Medical School, she completed an Internal Medicine Residency and Pulmonary & Critical Care Fellowship at the University of Iowa Hospitals and Clinics in 2002 and 2005, respectively. In 2005, she joined the faculty at the University of Iowa. She moved her clinical and research program to Dartmouth in 2009.
