We aim to understand how viruses breach the body’s key cellular barriers and establish infection, with a particular focus on the mechanisms underlying viral pathogenesis. In parallel, we work to translate these insights into more effective strategies for prevention and treatment. Our research focuses on three critical biological interfaces that play central roles in viral disease: the respiratory tract, the central nervous system, and the maternal-fetal barrier. These sites represent major points of entry, dissemination, and vulnerability, especially for viruses with significant impact on human and animal health.
