Current Research Projects:
Interferon-induced Transmembrane Proteins:
I am interested in how the innate antiviral immune response of different species (in particular bats) influences the emergence and pathogenicity of virus infections. I currently study interferon-induced transmembrane proteins (IFITMs), host cell proteins that block cell entry by numerous pathogenic and zoonotic viruses including influenza virus, lyssaviruses and filoviruses. I perform laboratory and phylogenetic analyses comparing IFITMs of different species (in particular bats, pigs and humans) to identify the molecular determinants of antiviral restriction by IFITMs. This can potentially enable us to harness IFITMs as prophylactic or therapeutic antivirals against high impact human and animal pathogens.
Peste des petits ruminants virus (PPRV) ecology and host range:
PPRV is a morbillivirus of small ruminants currently targeted for eradication by FAO. I am investigating PPRV infection in wildlife hosts, funded by The Royal Society, with the aim of advancing our understanding of the molecular mechanisms by which PPRV is emerging in novel species and of informing the PPRV eradication pathway. Find more at https://soulsbyfoundation.org/tanzania-and-the-peste-des-petits-ruminants-virus-or-pprv/ I am a Co-Investigator on an Innovate UK-funded grant to develop novel portable molecular diagnostic tests for PPRV and a GCRF Research Translation award to develop validated serological tests for atypical host species.
I studied immune modulation by vaccinia virus in the laboratory of Prof Geoffrey Smith FRS with the aim of developing more immunogenic vaccinia-vectored vaccines and novel anti-inflammatories. My work focused on the molecular mechanisms by which vaccinia virus blocks immune signaling pathways and the consequences for virulence and immunogenicity in vivo.
PhD Thesis: Investigation of the Antiviral Properties of Mx proteins
I studied the polymorphism and function of the interferon-inducible chicken Mx gene, with the aim of using variants of this gene to enhance influenza virus resistance in chickens. I gained extensive experience of working with influenza virus and of applying diverse molecular biology techniques.
