Adaptive extended reality,
grounded in human signals.

I’m Arindam Dey — a researcher, builder, and educator interested in multimodal XR systems that sense and adapt to how people perceive, feel, and respond. Most recently Staff Research Scientist at Meta Reality Labs (2022–2024); these days I also consult through Embute Labs.
