Dr Gerard Sheehan is a Research Fellow in the Prof. Robin May lab at the Institute of Microbiology and Infection at the University of Birmingham since September 2019. His main area of work focuses on is extracellular vesicles (EVs) from Cryptococcus gattii and their role in cell-cell communication and virulence. EVs are small (50-1000nm), secreted membrane ‘packages’ enclosing protein, RNA and carbohydrates. Dr Sheehan is more broadly interested in the interaction of fungi with their host as well as neglected tropical diseases. Previously, he obtained his PhD examining host – pathogen interactions using the Galleria mellonella larvae infection model and a range of important human pathogens such as Candida albicans, Aspergillus fumigatus, Klebsiella pneumoniae and Staphylococcus aureus at Maynooth University (Ireland). Dr Sheehan also utilises a range of ‘-omic’ based platforms including quantitative mass spectrometry to study the host – pathogen interactome.
