Publications

Research work on 3D perception, collaborative occupancy prediction, and efficient intelligent systems.

My publication record is organized around a long-term research direction: efficient and predictive 3D scene understanding for autonomous and embodied agents. Current work focuses on collaborative semantic occupancy prediction, bandwidth-aware token communication, and occupancy-based world models, with an earlier foundation in real-time scheduling for resource-constrained embedded systems.

The projects below reflect the trajectory I want to continue in Ph.D. research: building perception systems that are accurate, communication-efficient, temporally aware, and useful for downstream decision making.
