Gheyath K. Nasrallah

Postdoctoral Fellow


Gheyath (Goos) is a medical technologist by profession. He completed his PhD at Dalhousie University, Department of Microbiology and Immunology, in 2011. During his PhD, Gheyath used the yeast and the tissue culture model to explore the role of two bacterial genes, htpB & potD, in the pathogenesis of the fresh water pathogen Legionella pneumophila. Gheyath recently joined the Berman laboratory as a postdoctoral fellow to work on a Genome Canada-funded project entitled: Identifying Genes and Novel Therapeutics to Enhance Treatment (IGNITE). The IGNITE group will use the powerful genetic tools of yeast, zebrafish, tissue culture, and mouse models to discover novel genes responsible for a number of orphan diseases (ODs) prominent in Atlantic Canada. This multi-pronged approach will function as a pipeline to identify the underlying genetic lesions, validate the phenotype, and ultimately serve as a platform for developing small molecules and drugs targeting these ODs. Gheyath will be leading the efforts using the molecular biology tools afforded by the zebrafish model including phenotype characterization, morpholino knockdown injections, generation of transgenic models of the human disease, and chemical screens in the zebrafish embryos.
