UKA continued its policy of promoting from within by appointing Dunn as successor to Peter Eriksson following his move to replace Charles van Commenee in the Olympic set-up.
Eriksson and his staff, which included Dunn, masterminded a remarkable turnaround in Paralympic performance at London 2012.Following just two gold medals in Beijing in 2008 – both for David Weir – Britain won 11 on home soil as part of a total haul of 29. Wheelchair racer Weir again led the way with four golds, while Hannah Cockroft claimed two and Jonnie Peacock, Richard Whitehead, Aled Davies, Mickey Bushell and Josie Pearson won one each.
Dunn was an integral part of the Paralympic coaching team and takes up her new role with immediate effect.
"I'm so happy to be given this opportunity," the former 100 metres European bronze and Commonwealth silver medallist said. "I'm just going to do exactly what I've been doing, make sure the athletes get the best service possible and go on to better things.
"London 2012 had an amazing impact on Paralympic sport in this country and we've a real opportunity to build on that over the next four years. I believe there is more talent out there and I am looking forward to building on the success of 2012."
