Special Interests

My long-term research goals focus on understanding the function of macrophages during lung homeostasis and inflammation. I am interested in the ability of macrophages to perform multiple opposing functions over the course of an inflammatory response: driving inflammation and pathogenic tissue remodeling, as well as promoting resolution and repair. My research has focused on describing macrophage subsets within the lung and understanding signals that trigger macrophage reprogramming, particularly the clearance of dying cells by macrophages, termed efferocytosis.

In ongoing work, I am studying a link between efferocytosis, macrophage metabolism, and reprogramming of macrophage function as it relates to the resolution of inflammation/injury and development of fibrosis in the lung.

Patient Ratings

The Patient Rating score is an average of all responses to care provider related questions on our independent rating system, the Press Ganey Patient Satisfaction Survey. This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes.

Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.
