Hi there, I'm Xinyuan (Christine) Cui

"Mapping the unseen narratives of cities through spatial data and interactive design."

I am currently a Master of Urban Spatial Analytics (MUSA) candidate at the University of Pennsylvania (Expected May 2026). My work navigates the intersection of urban planning, geospatial data science, and web development. I believe in using spatial data not just to quantify cities, but to reveal the hidden human narratives within them—from transportation equity to the digital divide.

🗺️ What I Do

  • Spatial Data Science: Uncovering urban patterns using statistical modeling, spatial regression, and remote sensing.
  • Web GIS & Dataviz: Translating complex datasets into intuitive, interactive web experiences and beautiful static maps.
  • Urban Policy Analysis: Bridging the gap between raw data and actionable urban infrastructure planning.

🛠️ Tech Stack & Toolbox

  • Programming: R (tidyverse, sf, tidycensus), Python, JavaScript
  • Databases: PostgreSQL, PostGIS, Google BigQuery
  • GIS & Analytics: ArcGIS Pro, Geoda, Fragstats, SPSS
  • Design & Visualization: AutoCAD, Photoshop, SketchUp, Adobe Illustrator, Enscape, Ecotect, Mars

🌱 Currently Working On

  • 🚦 Analyzing Off-Peak Roadway Safety as a capstone with the Philadelphia Office of Transportation and Infrastructure Systems (OTIS), applying Random Forest regression (R² = 0.892) to quantify the off-peak fatality paradox and build an interactive dashboard for data-driven corridor prioritization.
  • 🏙️ Building a Philadelphia Property Appraisal (CAMA) Pipeline on Google Cloud Platform — orchestrating 9 serverless Cloud Functions to ingest ~580K property records into BigQuery, and developing an ML valuation model + dual-user dashboard serving 350,000+ properties.
  • 🛰️ Benchmarking Generative Models for Cloud Removal in satellite imagery — evaluating GANs and Diffusion models on 2,000 Sentinel-2 scenes using PSNR, SSIM, and NDVI to quantify hallucination thresholds for urban planning applications.

    What is the relationship between roadway safety outcomes and infrastructural, temporal and behavioral factors, specifically in off-peak hours?
