Dr Cath Mercer is a Senior Lecturer at the Centre for Sexual Health and HIV Research at University College London, and she is one of the lead researchers on Britain’s National Survey of Sexual Attitudes and Lifestyles. She is a trained demographer with an interest in sexual mixing, that is, who has sex with whom. Her interest lies in the transmission of STIs (sexually transmitted infections) with regards to the interaction between biology and behaviour. And not just the individual’s behaviour, but also their partners and their partners’ partners. In her talk, Cath explores changes in sexual behaviour and sexual partnerships observed in Britain, considering the effect of the internet and social media on sexual behaviour.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
