Nicholas Arger


Pulmonary immunology researcher, marathon runner, and chef

Dr. Nicholas Arger is a pulmonologist who specializes in caring for patients who have sarcoidosis, an inflammatory disease that primarily affects the lungs and lymph glands in the chest. Drawing on his extensive experience with the condition, he helps confirm a diagnosis of the disease and offers treatment approaches, screening recommendations, and long-term follow-up strategies.

Arger also sees patients with a wide variety of interstitial lung diseases, including patients with other chronic noninfectious granulomatous diseases that affect the lungs (including disorders associated with deficient immune responses that make the body more susceptible to infections). He also cares for patients in the intensive care units at UCSF.

As a member of the UCSF Sarcoidosis Research Program, Arger works with program director Dr. Laura Koth on research exploring immune mechanisms in the disease. By determining the roles played by certain white blood cells, he aims to identify biomarkers that can be used to predict patient outcomes and guide treatment.

Arger earned his medical degree at the Keck School of Medicine of the University of Southern California. He completed a residency in internal medicine at Yale New Haven Hospital and a fellowship in pulmonary and critical care medicine at UCSF.

Arger is a member of the American Thoracic Society, Americas Association of Sarcoidosis and Other Granulomatous Disorders, American College of Physicians, and Αlpha Omega Alpha Honor Medical Society.

In his free time, Arger enjoys cooking and running, especially on the Golden Gate Bridge. He has run the Boston Marathon twice and completed 18 other marathons.
