I am currently a Visiting Professor at the University of Sheffield, an Honorary Research Associate of the Smithsonian Institution in Washington, DC, and an Honorary Research Associate of the Institute of Zoology, Zoological Society of London. After obtaining my first degree in 1974 by passing the Institute of Biology membership exams, I obtained a PhD in 1979 through the Royal Veterinary College (London). I spent most of my professional life at the Zoological Society of London (ZSL) and retired in 2011; however, I still hold a position as Secretary of the ZSL Ethics Committee for Animal Research. In 2012, I was awarded the Setchell medal by the British Andrology Society, and then, in January 2018, the Society for Reproduction and Fertility awarded me their Marshall medal. Since retiring in 2011, and without having to contend with the burden of administration, I have co-authored more than 40 scientific papers and have also planned and co-edited three books.
