Elin Rhys grew up in Solva, Caernarfon and Llanelli. A graduate in Biochemistry from the then University of Wales Swansea in 1978, she worked as a scientist with the Welsh Water Authority for five years before embarking on a career as a television presenter with HTV, BBC Schools and S4C in 1984.

In 1993, she founded her own television company with the aim of popularising science in the media, and to do so mainly through the medium of Welsh. Today, Telesgop is a multi-media company and has its headquarters in the city of Swansea. Telesgop productions – whether for television, radio or the Internet, in English and Welsh – are held in high esteem across the world. The company's most recent productions for S4C are Pobol Port Talbot which portrays the community of the town and its famous steel industry, Her yr Hinsawdd, which considers changes in the global climate and, specifically, its impact on Greenland and the Maldives and Ffermio, a weekly countryside and agcriculture current affairs series. For BBC Wales, Telesgop produces coverage of the Royal Welsh Show and many observational documentaries around Wales. Telesgop’s most recent metwork production is Music for Misfits, The History of Indie Music for BBC Four, and Edward the 8th’s Murderous Mistress for Channel 4.

Elin has built an impressive public reputation, and her comments and advice on issues such as leadership, equality in the workplace, and issues associated with broadcasting and the Welsh language are held in high regard, so much so that the Welsh Government called upon her to chair the Task and Finish Group on 'The Welsh Language and Economic Development' which published its recommendations in 2014.

Elin is an active member of the University Council, appointed by the University Court, and also works with the University’s Employability Academy Strategic Board. In July 2016 she was awarded an Honorary Degree by the University.
