Professor Barratt is Head of the Reproductive Medicine Group at the University of Dundee as well as a clinical scientist (Hon) with NHS Tayside. He graduated with an Honours degree in Zoology and then completed a Post Graduate Certificate in Education (University of Wales, Swansea). His PhD, also in Zoology, was under the supervision of Jack Cohen (sperm selection fame) at the University of Birmingham. His formative post-doctoral studies and IVF experience was gained at the University of Sheffield [with Ian Cooke] where they specialized in natural cycle IVF. From 1997-2005 he was the Scientific Director of the ART Centre at the Birmingham Women’s Hospital. In 2002 he was awarded Young Andrologist of the Year (American Andrology Society) for outstanding contributions to the discipline. He is a regularly invited speaker at national and international scientific conferences/workshops. He was a member of the WHO Male Fertility Semen Analysis Taskforce (for both the 4th and 5th editions) and is now director of the new WHO (2012-2016) Male Fertility Expert Working Group which is devising a new system for the diagnosis and treatment of the infertile male. He was a member of the Human Fertilisation and Embryology Authority for 6 years. He has been on the Editorial Board of Human Reproduction, Human Fertility, Biology of Reproduction, Human Reproduction Update and Journal of Andrology. In 2014 Professor Barratt presented the Professor Sir Robert Edwards keynote lecture at ESHRE. This presentation was based on the highest downloaded paper in Human Reproduction for 2013.
