Research Interests

My clinical research centers on aspects of laboratory testing involving viral, immunologic, and molecular diagnostics, with a specific focus on the implementation of next-generation sequencing approaches. My basic science interests explore mechanisms governing host-pathogen interactions with ongoing research projects around the development of a murine cytomegalovirus model study innate immune control by natural killer cells and trafficking of virus during neonatal infection.
