At Roblox, our researchers drive our vision to reimagine the way people come together. We have over 100 PhDs collaborating across the fundamental Roblox Research team and applied Data Science & Analytics, User Research, and advanced engineering R&D teams. Together, they invent the future of Roblox, helping us truly deliver on our value of “taking the long view.”

The Roblox Research scientists publish findings in academic conferences, release open source and data, collaborate with universities, and bootstrap transferring results into production. Here are the team members responsible for that innovation.
