Geraldine Butler is Professor of Genetics at University College Dublin, since 2012. She is also a Principal Investigator at the UCD Conway Institute, and director of the Wellcome Trust PhD Programme in Computational Infection Biology. She is an editor of Eukaryotic Cell (and soon for mSphere), and also of PLoS Genetics. She was elected a fellow of the Royal Society of Biology (UK) in 2011, and a member of the Royal Irish Academy in 2015. The Butler lab is interested in determining factors controlling virulence in pathogenic fungi, and in particular in identifying the regulatory pathways controlling the growth of biofilms of Candida parapsilosis on medical devices; investigating the response of pathogenic yeast to hypoxia; and characterising the role of specific fungal transcription factors in virulence. The group uses a combination of laboratory and bioinformatics approaches, such as comparative genomics, transcript profiling, and chromatin immunoprecipitation. They have developed tools to facilitate genome analysis of Candida species, including the Candida Gene Order Browser, CGOB (http://cgob.ucd.ie).
