  • Ph.D.Fungal Biology and Bioinformatics, Maynooth University, Ireland

  • B.Sc.Biology, Maynooth University, Ireland


My research focuses on the use of metaproteomics, as a complementary method to metagenomics, to understand the developmental microbiome (Devome) of mushroom development.


My current work is focused on the use of proteomics to decipher the structure and function of the mushroom casing microbiome and the potential roles of microbial communities in mushroom development and disease suppression.
