My Biography & Research


My early work with outstanding mentors, who were pediatric rheumatologists, led me to pursue my clinical and research interests. During my fellowship, the unfortunate death of a patient from macrophage activation syndrome (MAS) prompted me to further study this life-threatening complication of systemic juvenile idiopathic arthritis.

Currently, I focus on identifying risk factors and new therapeutic targets in MAS. Our transnational studies have identified interferon gamma (INF), a dimerized soluble cytokine, as a therapeutic target in patients suffering from MAS. This discovery provided the rationale for a new clinical trial that is currently underway.

My research is funded by the National Institutes of Health (NIH) and the Systemic Juvenile Idiopathic Arthritis (SJIA) Foundation. I have also received research grants from Sobi, Novartis and AB2Bio.
