About

Huirong Chai

Huirong Chai is a PhD researcher at Georgia State University working on human–computer interaction. Her work runs along two lines: measuring what language models actually cost at runtime on phones and edge hardware, and examining how the field evaluates whether systems can anticipate human movement well enough to share a space with people.
