He is the co-creator and lead member of the electronic dancehall music project Major Lazer, a member of the supergroup LSD with Sia and Labrinth, a member of electronic duo Jack Ü with producer and DJ Skrillex, and a member of Silk City with Mark Ronson.

Diplo worked with and dated British musician M.I.A., an artist who is credited with giving him exposure in his early career. Later, he, M.I.A., and fellow producer Switch created a Jamaican dancehall project and cartoon series titled Major Lazer. Since then, Diplo has worked on production and mixtape projects with many other pop artists, such as Gwen Stefani, Die Antwoord, Britney Spears, Madonna, Shakira, Beyoncé, Ellie Goulding, No Doubt, Justin Bieber, Usher, Snoop Dogg, Trippie Redd, Chris Brown, CL, G-Dragon, Bad Bunny, Kali Uchis, Joji, MØ and Poppy. His alias, short for Diplodocus, derives from his childhood fascination with dinosaurs.
