Dario Seyb

Graphics Engineer at Valve

I work on making games look and feel great. My background is in computer graphics research — I spent years figuring out how light bounces around virtual worlds, how to represent complex shapes efficiently, and how to make all of that run in real time.

Before Valve, I was a Senior Research Scientist at Meta Reality Labs working on real-time holographic display rendering and neural graphics. I earned my PhD in computer graphics from Dartmouth College, where my research earned both a SIGGRAPH Best Paper and a Best Paper Honorable Mention.
