Capable of playing on both sides of the scrum, Doran-Jones' career started at Lansdowne Rugby Club in Dublin whilst he was at University in the city.
He had a spell with Kings Country in New Zealand and four seasons with Leinster from 2003 to 2007 before spending the past two seasons at London Welsh and also playing for London Wasps in their Guinness A League triumph in 2008.
He has represented England at U18 level and Ireland U19s and U21s in their respective Six Nations and World Cup squads.
Doran-Jones said today that he'd had offers to join other clubs but had been so impressed with the Kingshom set up that it had been an easy decision.
"I did have other options but I met up with Dean Ryan and Carl Hogg and what they had to say about developing me as a player really struck a chord."
"I'd also never visited Kingsholm and I got an awesome feeling from the stadium and the city. There's so much pride and tradition there but also so much potential. I really wanted to be a part of that."
Head Coach Dean Ryan added:
"Paul's had a very good grounding in National League Division One and more than held his own against some very good front rows."
"We think he's one for the future and can develop into a very good Premiership player."
