The research in my lab combines important aspects of virology, immunology, and cell biology to dissect various aspects of host-virus interactions, with a particular focus on polarized cell types. In particular, we focus on—(1) on the mechanisms by which enteroviruses have evolved to successfully circumnavigate the barriers presented by polarized cells to facilitate virus entry, replication, and spread, (2) on the mechanisms utilized by enteroviruses to evade and/or suppress innate immune signaling,  (3) on the identification of novel regulators and components of the innate immune system, and (4) on the role of placental-specific microRNAs in antiviral signaling and the induction of autophagy at the maternal-fetal interface.
