Finding the signal
in every movement.
I’m Jiuhui Xu — a student researcher, mathematical modeler, and dancer. I build systems that turn motion into insight, then carry that thinking into teams, stages, and communities.

01 / APPROACH
One mind, multiple modes
Research and dance are not opposite worlds.
Both ask the same questions: What is the system doing? Where is the imbalance? How can a precise adjustment change the whole outcome?
Drag the lens
Feel the whole system.
Choreography, spatial awareness, rehearsal design, and embodied precision.
Observe closely
Start with the human reality: an injured dancer, an unstable model, a team under pressure.
Build structure
Turn ambiguity into variables, roles, experiments, or a rehearsal system people can use.
Revise in motion
Test, notice what fails, and improve the system without losing sight of the people inside it.
02 / SELECTED WORK
Projects as living systems
Choose a lens. See the work reorganize itself.
Initiated a video-based system to assess the completeness and quality of ballet turns. Designed the expert-labeling workflow, recruited ballet specialists, and expanded the usable video dataset after diagnosing limitations in the original samples.

REVIEW SIGNAL
“Very innovative” · “Very high technical quality” · “Top quality”
Built and cleaned a substantial text corpus, ran pilot calculations, diagnosed unstable outputs, and repeatedly revised the data-collection strategy. The paper connected mathematical reasoning with literary interpretation.
Synthesized PNIPAM-HPC and PNIPAM-PAM hydrogel specimens for controlled comparison. Measured tradeoffs across responsiveness, robustness, shrinkage, and reversibility, then presented a poster at the 11th ICAEE conference.
Self-studied differential equations, physics-informed neural networks, and 3D Gaussian Splatting. Synthesized the mathematical background, current limitations, and a proposed combined research pathway.

Two working projects turn different parts of my practice into experiences people can use: one listens with children; the other reads movement with data.

Keep the story.
A gentle English picture-book audio library for young listeners, with eight stories, saved progress, favorites, playback controls, and a sleep timer.

BaTec · Ballet Turn Assessment
Movement becomes
measurable feedback.
A live video-analysis interface for ballet turn completion and movement quality, translating a performance into an assessment dancers can inspect.
Each portal opens the working project in a new tab, so the resume stays as your map while the work becomes the destination.
04 / IMPACT
Beyond the model
A good system should help people move together.
01
Cheer Up Cheerleading Club
Founded an inclusive school club, taught dancers in small groups, and unified different experience levels into one performance standard.
Founder · Choreographer · Student coach2,000+
A program that traveled
Combined jazz, cheerleading, and contemporary dance into an accessible group program that spread across multiple campuses.
Cross-school exchange · Formation designA/V
Literature in performance
Turned reading into discussion, drama, audio production, original music, and a campus-life video — shaping structure, pacing, and interpretation.
Organizer · Director · Performer300+
Books, tools, and attention
Organized reading events for young children, donated books across three provinces, and shared study methods and technical tools with younger students and teammates.

What else can
motion reveal?
I’m exploring the space where data, people, and embodied experience meet.
