Faculty 2017

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.

Ann Wrightson

Ann Wrightson

In the late ‘70s I left the University of Cambridge with a BA in Philosophy and
an even stronger addiction to books than when I left school, so it’s no wonder
that my first job was in publishing. I’d also acquired a fascination for logic
and some programming skills, so my first job was actually as a programmer in the
brave (fairly) new world of electronic publishing. I spent the next thirteen
years in that little-world, including seeing the European side of SGML
standardization at first hand, and helping start off the SGML Users Group. Then
I was made redundant from a project to build a newspaper system, picked up a
temporary lectureship to keep the family and spent the next ten years as an
academic paying more attention to formal methods, systems analysis & human
computer interaction than to markup.

When XML came along I was gradually pulled back into markup languages and
standards, & ended up playing seriously with Topic Maps and eGovernment
interoperability standards in the early 2000s. By 2004 I was in my first HL7 CDA
project and gradually the rest of the world dropped away as I strayed further
& further into Health Informatics. These days I’m an enterprise architect
who (oddly) goes hands-on with systems analysis & data mapping rather than
networks or coding, and gets all geeky about interoperability payloads and end
to end semantic integrity.
