Papadopoulos, a research scientist and practising psychologist, will work closely with eHarmony’s PR agency, Third City, in an ongoing PR exercise to design and front the site’s new advertising campaign, ‘Brains behind the butterflies’.
She will also support the brand’s UK activity and provide advice to singles via media channels online and in print.
In addition, Papadopoulos will be working on eHarmony’s Compatibility Matching System – one of the brand's core elements, which uses science to match singles based on 29 dimensions of compatibility.
She said: "The science behind this relationship site is not only what sets eHarmony.co.uk apart, but ultimately delivers its members with quality matches that they’re truly compatible with. When it comes to love, it’s about quality not quantity, and I’m really excited to be involved with a brand that holds these values at its core."
eHarmony works with researchers from Oxford University carrying out scientific research into love, long-term relationships and marriage.
Romain Bertrand, managing director of eHarmony, said: "Her extensive experience means she’s an expert in understanding people – something that we also pride ourselves on. Both her academic and creative input will be invaluable in communicating and demystifying the science of relationship psychology and ultimately how singles can achieve better matches."
