Stefano (Stef) Corazza joined Roblox in July 2022 as the new Head of Roblox Studio, one of the most used 3D immersive content creation software tools in the world. Prior to Roblox Stef led a team responsible for building out Adobe’s AR strategy. He was also involved in leveraging machine learning to democratize content creation.

Under his tenure at Adobe, the company's 3D organization grew from three employees to over 200 people, making the 3D business one of the fastest growing segments at the company. Growth was driven by the Substance 3D collection of tools, which Stefano drove the acquisition of as board member and executive sponsor. Stef joined Adobe via a 2015 acquisition of Mixamo Inc, an online software platform for 3D character animation that leveraged machine learning to democratize 3D animation. Mixamo was founded by Stef (also led as CEO/CTO before its acquisition) and it currently helps - as part of Adobe Creative Cloud - hundreds of thousands of game developers and animators every month to create character animations in seconds. Prior to Mixamo, Stef was a research associate at the Stanford University Biomotion Lab, where he developed markerless motion capture technology and won the Stanford-Caltech-Berkeley Innovators' Challenge in 2005. He holds a Bachelor of Science in Mechanical Engineering from University of Padua, a Master of Design from University of Florence, a Ph.D. in Mechanical Engineering and a Ph.D. in Bioengineering and Computer Vision from University of Padua, part of which was completed at Stanford University.

Stef has also built art installations for museums and festivals in the past and founded the Festival of the Impossible, an immersive experience festival celebrating artists who are pushing past the boundaries of reality. Stef holds over 40 patents, the majority of which are in the animation and motion capture domains where he has published over a dozen peer reviewed papers and over thirty conference proceedings.

Stef is involved as angel investor and startup advisor, notably in the past with Matterport (now public as MTTR), Artomatix (acquired by Unity), Evertoon (acquired by Niantic), and others. And he is on the board of Rokoko.
