Josh Giegel is the CTO and Co-Founder of Virgin Hyperloop One, where he is leading a world-class team of engineers making the hyperloop a reality.

Josh brings with him an unmatched background in thermodynamics, heat transfer, compressible fluid mechanics, power cycles, turbomachinery, nonlinear structural analysis, as well as a strong history in hardware-based development. He is leading the design, analysis, and innovation for thermodynamic elements of the hyperloop system. 

Previously, Josh led research activities at Echogen Power Systems, a startup in the waste heat-to-power energy sector. Josh was the sole inventor of four novel supercritical CO2 power cycles that significantly improved efficiency and lowered cost. He also developed custom multi-objective, nonlinear optimization software which provided solutions in real-time to drastically reduce engineering man-hours.

Prior to Echogen, Josh worked at SpaceX where he served as the lead analyst on six different successfully tested rocket engines including the Merlin 1D and Super Draco family of engines. Josh's analysis was also critical to the success of the Dragon spacecraft where microgravity propulsion systems are an integral piece in the docking and deorbiting from the International Space Station. He received an "Ass-Kicker" award for his work identifying and replicating the Falcon 9 first flight anomaly, and decisively protecting against future such events.          

Josh received an MS in Mechanical Engineering from Stanford University where he was a Graduate Engineering Fellow. He holds a BSME from Penn State University where he graduated with honors and was first in his class.
