Dr Bernie Owusu-Yaw was a Volunteer Writer at BioNews, having originally joined the publication under the auspices of its writing scheme. She has completed a PhD in Neuroscience at University College London, where the aim of her research was to develop models of inherited prion diseases. The models will be used to investigate the molecular mechanisms of these diseases.
