Under this partnership, Leinster will establish a new high performance training unit on UCD's Belfield campus adjacent to UCD's state-of-the-art Institute of Sport and Health (ISH).
In addition, the newly-crowned Heineken Cup champions will avail of UCD's extensive suite of top class synthetic and grass pitches.
Players will have access to UCD's expanding suite of physiological and biochemical testing platforms and sports medicine facilities.
Research collaborations will be developed in areas such as high performance science, sensor technology, bioengineering and sports physiology.
Educational collaboration will see an increasing number of Leinster players enrolling in UCD courses, using the flexible modular UCD Horizons curriculum to prepare for a career after rugby.
The partnership builds on existing strong links between UCD and Leinster Rugby. Jonathan Sexton, Gordon D'Arcy and Devin Toner are current UCD students and four of the province's Heineken Cup-winning team are former UCD players - Brian O'Driscoll, Sean O'Brien, Kevin McLaughlin and Fergus McFadden.
