Faculty 2014

Our lecturers are hand-picked for their in-depth expertise and ability to convey
their experiences to maximise the learning experience of our delegates. They also
are friendly, approachable, and able to have a good laugh! The intensive, yet
informal, atmosphere at the XML Summer School gives delegates the opportunity to
pick the brains of our expert faculty, both during the classes and afterwards over
meal or in the bar.

The Faculty Board operates under the stewardship of Course Director, Dr Lauren Wood.
Each year it decides on the appropriate courses and curriculum and invites the
fantastic array of experts to prepare and deliver classes.
