An education publishing company is to invest €350m in e-learning research and development in Ireland.

Houghton Mifflin Harcourt, formerly known as Riverdeep, says it will create 450 jobs at a new centre in the greater Dublin area over the next five years.

The firm says the new centre will drive innovation in digital learning for children globally and strengthen the e-learning industry in Ireland.

The investment is being supported by Enterprise Ireland and is the single largest research and development project in the history of the State.

The company said its decision to centralise all its development in the new centre is based on the fact that Dublin provides the best hub located uniquely between east and west.

The exact location of the new centre is yet to be confirmed.
