Synthetic radar data supporting sensing models across multiple environments

Physics-Based Radar Data Synthesis

Generate controllable human and animal motion, place it in sensor-agnostic RF scenes, and use RFDT—a physically based differentiable RF ray tracer—to produce labeled radar training data.

  • Designed data across subjects, behaviors, and environments for activity recognition.
  • Collected real human and pet activities including walking, sitting, lying down, falling, and jumping.
  • Co-authored the forthcoming ACM MobiCom 2026 demo, Differentiable Radio Frequency Digital Twin.
WiTwin Studio interface for simulation preparation and 3D scene authoring

WiTwin Studio

Built simulation preparation workflows that connect interactive 3D scene authoring with a Python simulation backend.

  • Developed tools for graphics assets, motion matching, animation timelines, and interactive visualization.
  • Added natural-language agents with scene and motion tools for multi-step workflows.
  • Defined execution boundaries between read-only planning and scene-changing actions, with regression coverage and saved-scene restoration.

CWC Research Intelligence Platform

Built an evidence-backed system for more than 20 faculty members, combining searchable profiles, monthly activity digests, and collaboration discovery.

  • Consolidated source evidence with identity verification and provenance.
  • Generated summaries, themes, and keywords with unsupported-claim checks and deterministic fallbacks.
  • Built a searchable WebHub, monthly GitHub Actions workflow, and a correction loop for user feedback.
