The hiring decision was announced by Oscar telecast producers Adam Shankman and Bill Mechanic.
"We loved the look and feel that David created for the Oscar show last year," Mechanic said in a statement. "As soon as we signed on as producers, Adam and I knew that we wanted to work with him for our show."
"David is so creative and has such a great big-picture approach to set design," added Shankman. "I'm beyond excited to be collaborating with him on the Oscars."
