Dagan Wells has been actively involved in pre-implantation genetic diagnosis (PGD) and the study of human gametes and embryos for the last 25 years. He spent several years developing novel PGD tests at the University College London (UK), accomplishing the first comprehensive chromosome analysis of cells from human embryos in 1998, using a combination of whole genome amplification and comparative genomic hybridisation. In 1999 he moved to the United States and joined Reprogenetics, one of the world’s largest providers of PGD services. In 2003 he initiated Reprogenetics’ single gene PGD program, testing embryos for numerous serious inherited conditions. Dagan later
joined the faculty of Yale University Medical School (New Haven, USA) where he set up a PGD and research laboratory before returning to the UK in 2007. He is now an Associate Professor at the University of Oxford, overseeing a research team based at the Nuffield Department of Obstetrics and Gynaecology. Dagan’s work has led to the publication of more than 150 peer-review publications and book chapters and has been recognized with the award of numerous prizes and grants. He is a Fellow of the Royal College of Pathologists and currently serves on the editorial boards of several international journals. Dagan also directs Reprogenetics-UK, a laboratory offering PGD services to IVF clinics in Europe, Africa and the Middle East.
