The 27-year-old former Munster player had moved to Zebre from Lazio Roma at the start of the 2012/13 campaign, playing 20 PRO12 games for the side and making six Heineken Cup appearances.
Thanking both Zebre for their support and Ulster for the new opportunity, Ryan said: "I have developed a lot as a player and a person during my time in Italy.
"While a part of me is sad to leave, the opportunity to join a team with the quality and character of Ulster was too great to pass up."
I'm excited to start a new chapter in my career with a team I have always admired for their work ethic, style of play and physicality.
Ulster's Director of Rugby David Humphreys added: "Dave is an experienced Irish prop with solid experience in both the PRO12 and Europe.
"He adds further squad strength to the key position of tighthead prop and I have no doubt that he will be a huge success at Ravenhill."
On Tuesday, Ulster confirmed that they were facing a considerable casualty count.
Ruan Pienaar will be out with a shoulder injury for at least six weeks, while Rory Best's ankle sprain sidelines him for six to eight weeks.
Dan Tuohy and Roger Wilson will also both be out for lengthy periods, with a fractured hand and a fractured thumb respectively.
Meanwhile John Afoa misses Friday's PRO12 clash with Connacht due to a back injury and Andrew Trimble has to follow return-to-play protocols after being concussed in Ulster's defeat by Saracens.
