Tim Ellis is an American aerospace engineer and the co-founder and former CEO of Relativity Space.[1]
Early life and education
Ellis grew up in Plano, Texas.[2] He is the oldest of three children.[3]
Ellis started college at the University of Southern California, where he planned to graduate and be a screenwriter, and study as part of USC’s Thematic Option program.[4] However, during his freshman orientation he switched his major to aerospace engineering.[3] Ellis and Relativity's other co-founder and CTO, Jordan Noone, both held leadership positions at USC's Rocket Propulsion Lab (RPL).[5] Within RPL, Ellis and Noone helped launch the first student-designed and built rocket into space.
While at the University of Southern California, Ellis had three consecutive internships with Blue Origin.[4]
Ellis holds a BS and a MS in Aerospace Engineering from USC Viterbi School of Engineering.
