Charlie Vuong — HCI researcher, maker, and sensing technologist
Hi! I’m Charlie (he/him/they), born in HCMC, Vietnam. Based in Dallas-Fort Worth, TX.
I’m a PhD candidate in Human-Computer Interaction at the University of Texas at Arlington, working under Cesar Torres in The Hybrid Atelier.
My HCI research
Building sensing systems and interactive tools that work with materials—especially fluids—through rheological visualization, supporting materials literacy for creative and interaction design.
