During my training as a doctor, I was struck by the difficulties patients with pulmonary fibrosis faced, with no access to a treatment that could stop the disease. I was motivated to take a step back from directly caring for patients to dedicate my time to understanding what is actually happening in the lungs. The APF Fellowships, recognized for supporting pioneering research in this field, offer me a unique opportunity to try to uncover new treatment targets and improve outcomes for patients.
