Narrative:

I was working east high position and received handoff on DH8 climbing to FL50. I had no traffic so I flashed the aircraft on the next sector (gibbs) and they flashed it on to ZMA. Therefore controller working east low sector turned the aircraft (DH8) on course and climbed him to FL120. A few mins later, I received a handoff from the gibbs sector, an E120 level at 110 nebound toward the DH8 who was still slow climbing through the gibbs airspace. The previous controller was training and failed to see that the airplanes were heading toward each other and were not separated. The E120 was switched to my frequency level at FL110. I had to take evasive action and turn the E120 sse to miss the DH8.
