Dr Samantha Loveless
(she/her)
BSc (Cardiff), PhD (Cardiff)
Lab Manager, Division of Psychological Medicine and Clinical Neurosciences
Overview
I am currently employed as the Biorepository and Laboratory Manager for the Academic Neurology Lab based at Cardiff University's UHW campus.
My role involves the management of the Welsh Neuroscience Tissue Bank (WNRTB); the ethical approval, consent, collection, storage and allocation of neurology patient samples for the biobank, as well as other specific neurology projects (SNOWDONIA, Epilepsy-Bio) and biobanking arms of Multiple Sclerosis (MS) clinical trials (such as Octopus and DELIVER-MS), co-ordinating sample collection and distribution across multiple national and international sites.
I manage the laboratory and facilities as well as a team of research technicians for the MS research group and BRAIN Unit, supporting research into a wide range of disorders including MS, NMO, epilepsy, MND, glioblastoma, IIH.
My research focuses mainly on fluid biomarkers in MS with several collaborative papers published to date.
