"I have thoroughly enjoyed my time working with Leinster and have grown as a coach at the province," he said.
"I am excited to be taking on this new role.
"There is some good scrum talent across all four provinces but there is always plenty to work on as we attempt to maximise the growth and development of the emerging talent while also staying as competitive as possible at the top level."
