Dean Ivory Stable Jockey?

Anyone have any idea who is his stable jock?

Going by the stats its not too clear to me, but have heard someone go on about info from the stable jockey and it would make my decisions a little easier in balancing up that info if I knew who this was, I could maybe go back through result history and see what horses said jockey was on and how successful they had been etc etc.

TIA for any help folks.
