Undergraduate Student Researcher

Toronto Robotics and Artificial Intelligence Laboratory
  • Contributed in an LLM-based agentic workflow for robotic navigation with long-term memory, enabling scalable task-conditioned retrieval for long-horizon multimodal robot memory
  • Developing undergraduate thesis that integrates vision language navigation with a novel real-time scene-graph memory module to support high-level navigation tasks and apply this system to real-world deployment with RL-based Husky robot locomotion

Student Researcher

Robot Vision and Learning Lab @ UofT
  • Developed a sparse view 4D Gaussian Splatting reconstruction algorithm for use in real-world robot tasks that achieved superior reconstruction quality under minimal camera setups, cutting the number of input views needed for reconstruction from ∼20 to ∼4. This work will be integrated into the group’s adversarial study on iterative-policy-learning.

Co-op Researcher - Autonomous Driving

Noah's Ark Lab, Huawei Canada
  • Research on enhancement and refinement of relightable 3D Gaussian Splatting
  • Develpoed an algorithm called UniGaussian that integrated fisheye and pinhole camera models for 3D Gaussian Splatting reconstruction in autonomous driving scenarios via Unified Gaussian Representations
  • Developed a novel single-image–to–3D reconstruction pipeline to address fine-detail loss in diffusion-based 3D asset generation.
  • Participated in simulating on group's end-to-end pipeline for autonomous driving
