My experience with fluorescence in situ hybridisation (FISH) began in a research setting, when I was studying thyroid development and related disorders. Since then, my knowledge of FISH has expanded greatly, especially in the processing of FFPE samples. As a former in-house specialist for an in vitro diagnostics (IVD) company I am aware of the difficulties which people in FISH labs face. This experience supports me in my role as a Field Application Specialist at Oxford Gene Technology, where I am committed to helping our customers overcome any difficulties they are having and making sure their FISH processes are completely optimised.
