Gemili and Dasaolu both enjoyed a fine 2013 season with the former becoming the second fastest Brit ever over 200m at the Moscow World Championships.
The 20-year-old clocked 19.98seconds to qualify for the final, where he placed just 0.04 shy of bronze in fifth, and also collected European under-23 gold over 100m.
Dasaolu meanwhile became the second fastest Brit ever over 100m with 9.91 at the world trials in Birmingham and went on to finish eighth in Moscow.
Gemili has now moved to Dasaolu's base in Loughborough to train under sprint coach Steve Fudge, leaving Michael Afilaka and London behind.
"You've obviously got Usain Bolt and Yohan Blake training together, and they're the quickest guys in the world, so to have me and James training together can't be a bad thing," Gemili told the Daily Telegraph.
"He's the only Briton this year to go sub-10 and I'm the only Briton to go sub-20, so it can only be positive for us to train together."
