Our research focus is on inflammation regulation and leukocyte biology. Leukocytes of particular interest are innate immune cells, including neutrophils-the most abundant leukocytes in the blood and first to respond during bacterial infection. A key function of leukocytes that we study is ectodomain shedding. A proteolytic process that has localized and systemic effects, and when dysregulated promotes excessive inflammation and immunosuppression during infection and cancer.
