Autoimmune and autoinflammatory disorders are a significant cause of morbidity and mortality worldwide. Complex interactions between multiple genetic and environmental factors are essential for the development of these disorders. Our laboratory is interested in understanding how autoimmune responses are initiated, amplified and how they cause tissue injury and pathology.
Sjögren’s syndrome is a chronic autoimmune disorder responsible for causing severe dry mouth, dry eyes, and fatigue. Our laboratory investigates how non-specific activation of the immune system by viruses and bacteria can lead to the development of Sjögren’s syndrome.
Recently, our laboratory has started working on an inflammatory disorder, Sarcoidosis, that mainly affects the lungs. We are developing experimental model systems to test the efficacy of different therapeutics to treat this enigmatic disorder.
Activation of innate immunity by danger signals emanating from external and internal sources is a crucial first-line defense mechanism. However, excessive and chronic activation of innate immunity can lead to autoinflammatory and autoimmune disorders.
The primary focus of my laboratory is to investigate how innate immune responses contribute to the pathology of Sjogren’s syndrome and Sarcoidosis. Our lab integrates human clinical research with disease-relevant animal model systems to gain in-depth knowledge of disease mechanisms. We feel this is key for developing novel diagnostic and therapeutic strategies to treat autoimmune and autoinflammatory disorders.

When Chip Morgan met the first class of Polish biology students to come to OMRF for a year-long training program in 2013, he couldn’t help but notice something. “They were all women,” says the foundation’s long-time executive vice president and chief operating officer. The next year, the story was the same. Ditto in 2015. “I […]
