Tim is cofounder and CEO of Relativity, the first autonomous rocket factory and launch services leader for satellite constellations. He has helped change the future of space exploration by expanding the possibilities of additive metal manufacturing. Under his leadership, Relativity developed the largest robotic metal 3D printer in the world and tested its entirely 3D printed Aeon rocket engine over 200 times, on track to launching Terran 1, the world’s first 3D printed rocket.

Prior to Relativity, Tim brought metal 3D printing in-house at Blue Origin and served as a Propulsion Development Engineer on Crew Capsule RCS thrusters, BE-4, and New Glenn. He holds an MS and a BS in Aerospace Engineering from USC, where he played a leadership role in launching the first student-designed and built rocket into space together with Relativity cofounder and CTO Jordan Noone.
