Only 43, British choreographer Wayne McGregor has already had a full career. He’s the artistic director of Wayne McGregor Random Dance, the resident company at Sadler’s Wells Theatre in London. He’s also the resident choreographer of the Royal Ballet. He’s been a research fellow in the Department of Experimental Psychology at the University of Cambridge, and he’s worked with economists, anthropologists, computer scientists, and neurobiologists. Oh, and he was the movement director for “Harry Potter and the Goblet of Fire.” Not bad for a kid from Stockport, England, whose initial role model for dance was John Travolta in “Grease” and “Saturday Night Fever.” This week, he’s in town to rehearse Boston Ballet in his 2006 piece “Chroma.” Full story for BostonGlobe.com subscribers.
