I am an immunologist with a keen interest in virus-host interactions. Currently I am focusing on different aspects of bacteriophages carrying anti-CRISPR genes, which facilitate the infection of bacteria using the CRISPR-Cas system to defend against phages. Previously I investigated the function of novel orthopoxviral immunomodulators during infection of mammalian cells at Trinity College Dublin.


In collaboration with Andrei Serpe (3rd Fine Art BA(Hons) at Falmouth University), I am creating a graphic novel entitled "Rock, Paper, Scissors - When microbes play games" (http://rpsnovel.tumblr.com/), which illustrates the struggles between viruses that infect bacteria and their bacterial host. The project received seed funding from the ESI Creative Exchange Programme. The development of the fully illustrated coloured graphic novel and exhibitions thereof are financed by the European Society for Evolutionary Society, the Genetics Society and the Microbiology Society
