During his four years at Craven Cottage, the 47-year-old helped the club preserve their Premier League status and appoint Roy Hodgson as boss. He also had a four-year stint as sales and marketing director at Glasgow giants Celtic.
He told the club's official website: "It was the size of the club and knowing what a fantastic fanbase it has, with so many loyal supporters, which were the main factors in me wanting to take up this challenge. The club has so much potential and so many strengths and I'm excited about working to help capitalise on that in the months and years ahead.
"It was also the passion of the owners and directors in the shape of Delia Smith, Michael Wynn Jones and Michael Foulger which attracted me. It's so important to have people at board level who share passion for the football club and the directors here definitely have it.
"Clearly promotion from League One is essential - everyone in the football club needs to be focused on getting us back to the Championship. Consolidation for a season is not something I would be interested in and I sense I'm not alone in that.
"Of course no team has a divine right to promotion from any division but the fact remains the size of the club and its support demands a positive attitude and a commitment to promotion as the objective. It's about sheer hard work from everyone at the club, that is what will give us the best chance of achieving the objective we all share."
