Dr Wells’ current research programme is focused on increasing understanding of the molecular genetic processes underlying gametogenesis and preimplantation development. His laboratory has a strong translational emphasis and is actively involved in the development of new PGD methods that are more comprehensive and more reliable than those in current use. Dr Wells’ research also aims to create novel techniques for improving the success rates of IVF treatment.

Biography
Dagan Wells has been involved in preimplantation genetic diagnosis (PGD) and the study of human gametes and embryos for almost two decades. He began his career at the University College London, where he supervised molecular diagnostics at the UCL Centre for PGD. During his time in London, Dr Wells was responsible for the first application of whole genome amplification to human embryonic cells and was involved in the first PGD case for a cancer predisposition syndrome. He was also responsible for developing the first method for reliably screening the entire chromosome complement in embryos and oocytes.
In 2000 Dr Wells moved to the United States and joined Reprogenetics LLC, one of the largest providers of PGD services in the USA. Shortly after his arrival he initiated Reprogenetics’ highly successful single gene PGD program, which has grown exponentially since its inception.
In 2003, Dr Wells’ moved to Yale University, where he spent four years as an Assistant Professor in the Department of Obstetrics and Gynecology. While at Yale Dr Wells and his group began clinical trials of comparative genomic hybridization (CGH), a comprehensive chromosome screening method, applied to blastocyst stage embryos. This approach has been associated with some of the highest in vitro fertilization (IVF) pregnancy rates ever recorded.
Dr Wells’ research team relocated to the Nuffield Department of Obstetrics and Gynaecology at the University of Oxford at the end of 2007. Dr Wells’ current research programme is focused on increasing understanding of the molecular genetic processes underlying gametogenesis and preimplantation development. His work has been recognized with the award of several prizes, including the American Society for Reproductive Medicine General Program Prize (2000) and the publication of more than 60 papers in peer-review journals.
Dr Wells has attracted funding from multiple companies and public bodies, including the National Institutes of Health (USA) and Medical Research Council (UK). He is a Fellow of the Royal Society of Pathologists and serves on the editorial boards of several international medical journals.
