Joe Rupertus
I graduated from Princeton in 2026, where I did research in human-computer interaction and published to CHI 2025. I've been an indie iOS developer since I was 16 and I won Apple's Swift Student Challenge in 2021.
I really like creating things that people find useful and fun. I believe in a future that takes advantage of new technology while preserving the things that make us human. I also like running, photography, and making travel vlogs.

About
I've always been someone who enjoys building and creating things in any form, whether that's art, videos, or apps. When I was 16 I was bored at home during COVID and taught myself how to make iOS apps by watching YouTube tutorials. I shipped four apps to the App Store and won the Swift Student Challenge.
At Princeton, I got involved with several startups and even tried founding my own company. I also did HCI research on human-AI collaboration and spatial computing. I presented a project about AI digital twins for crowd work at CHI 2025, and I wrote my senior thesis on inferring user intent from multimodal input in AR.
