Biography

My group's research focuses on the transcription-replication machinery of non-segmented negative strand RNA viruses. My work spans several viruses in different viral families, including Marburg virus, Nipah virus, respiratory syncytial virus, and parainfluenza virus. Although these viruses cause very different diseases, they all share common mechanisms to transcribe and replicate their RNA genomes. My group specializes in using biochemical and molecular biology approaches to probe functional properties of the transcription-replication machinery. We collaborate with structural biologists to understand how the structure of viral polymerases relates to their multi-functional properties, with industry partners to determine the mechanism of action of small molecule polymerase inhibitors with therapeutic potential, and with experts in microscopy to study how the transcription-replication machinery is organized and regulated in infected cells.
