Cowan, a former international over 110m hurdles, has been appointed by UKA's Olympic head coach Peter Eriksson and performance director Neil Black to take on the role in the build up to Rio 2016.
And having worked closely with Eriksson and Black in 2012 as a sprints coach for the Paralympic team he is keen to renew their blossoming partnership.
Cowan coached 2008 Olympic champion Ohuruogu ahead of this summer's Games – as well as Andy Turner, Shana Cox and Bianca Williams – and believes his methods can be used across the board.
But medals are the 39-year-old's main priority, and it's Ohuruogu's unexpected success on home soil that he claims stands him and Team GB in good stead.
"I'm delighted to have the opportunity to continue working with Neil Black and Peter Eriksson so that the athletes in my training group can continue their development and capitalise on the success of London 2012," said Cowan.
"It's important that we keep our momentum going to keep progressing and enjoy more good results in the future.
"Christine Ohuruogu's silver medal at the Olympics was a fantastic achievement and I'm sure we will build on that, as well as on the other great performances of the athletes in my training group during 2012, in the coming months and years leading up to the next Olympics in 2016.”
