Systemic autoimmune rheumatic diseases • systemic vasculitis • systemic lupus erythematosus • patient safety and quality improvement • medication safety

Research Focus

My research focuses on patient safety in systemic autoimmune rheumatic disease. I aim to improve medication safety in this population by studying root causes of adverse drug events, with a particular focus on glucocorticoids (i.e., prednisone) and other immunosuppressive agents, in order to design innovative strategies for improving medication safety in this population.
