Dr Hywel Williams is a Senior Lecturer in Bioinformatics at Cardiff University. His research is focused on using multi-omic techniques and big data informatics to better understand the biological basis of rare disease, with an emphasis on neuro-related phenotypes, and to help increase diagnostic rates and improve patient wellbeing. He will be co-leading our Genotype-Phenotype Association community which focuses on studying large-scale genotype-phenotype studies to uncover rare variants linked to traits and diseases.
