Preimplantation Genetic Diagnosis: The Who, the What, the Why and the How

Paul Waldron

Paul Waldron is a Volunteer Writer at BioNews, having originally joined the publication under the auspices of its writing scheme. He is currently studying for a PhD at University College London's Institute of Ophthalmology, where his research focuses on developing therapies for restoring vision in retinal diseases, by transplanting new light-sensitive cone cells into mouse retinas. He is also investigating how immature cone cells migrate during development. Previously, he studied Natural Sciences at Emmanuel College at the University of Cambridge, where he specialised in Cognitive Neuroscience.
