Applied ML + human-centered data work.
Jiaxi Zhou — PhD researcher (UPenn). I work at the intersection of behavioral modeling, social systems, and product decision-making, building end-to-end pipelines from messy logs/surveys to interpretable models and clear recommendations.
What I’m best at
Featured projects
🕸️ Network Analysis: From Social Ties to Actionable Segments
Network structure · communities · interpretable signals → interventions
Turns relational signals into actionable segments (communities, bridges, roles) so teams know where to intervene first.
📈 Trajectory Segmentation: Patterns Over Time → Targeted Interventions
Longitudinal modeling · latent classes · trajectories → strategy
Segments users by trajectory shape so interventions are timed and targeted, not averaged away.

Evidence of quantitative work (Google Scholar: 93 citations · h-index 6 · i10-index 4).
Writing (optional but powerful)
2–3 short posts that show judgement: evaluation, metrics, experiments, and how you translate evidence into decisions.
