Studying the regulatory roles of cellular miRNA on virus replication Studying the virus-induced miRNA response Identification of virus-encoded miRNAs and their effects on the infected cell life cycle Studying the host-virus proteins interaction Research Interests: Studying host-virus interactions using state-of-the-art technologies, including high-throughput sequencing, genome editing (CRISPR-Cas/TALEN) and genome-wide library scale RNA interference (RNAi) systems. Molecular pathogenesis of respiratory and enteric viruses, including Middle East respiratory syndrome coronavirus (MERS-CoV), influenza A virus and Enterovirus 71 (EV71). Studying regulatory roles of small RNAs derived from host and virus on virus replication and host response.
