Yaru Liu

Hi there! I’m a third-year PhD student in the Department of Computer Science and Technology at the University of Cambridge, advised by Prof. Rafal Mantiuk. My research sits at the intersection of Computer Graphics and Machine Learning, with a background in content-adaptive rendering and real-time 3D reconstruction. I care about world models and embodied AI safety.

Previously, I earned a B.Sc. in pure math at the University of Toronto and an M.Sc. in computer engineering at McGill University. I’m just an ordinary person who has been incredibly lucky to meet so many great people along the way. I’m deeply grateful for the guidance and trust of my PhD advisor Prof. Rafal Mantiuk, Prof. Derek Nowrouzezahrai and Prof. Morgan McGuire at McGill, and my supervisors at Tencent, NVIDIA and Huawei.

Beyond research, I love business and fashion. I’ve founded 3 startups, 1 of which was acquired, and I’m drawn to problems with high technical barriers. I’m driven by practical questions, and business often anchors my academic pursuits, while fashion is my creative therapy. To me, research, business and fashion don’t just coexist. They complement and elevate one another.

Feel free to reach out for collaboration🩵

Projects

Streaming of rendered content with adaptive frame rate and resolution
Yaru Liu, Joseph March, Rafal Mantiuk
Accepted to SIGGRAPH 2026
[Paper]

We exploit the spatio-temporal limits of the human visual system to adaptively adjust frame rate and resolution based on scene content and motion. A lightweight neural network predicts the optimal configuration to maximize perceptual quality while minimizing rendering load under bandwidth constraints. Our approach successfully optimizes perceived quality while reducing 50%+ computational costs.

V-CAGE: Vision-Closed-Loop Agentic Generation Engine for Robotic Manipulation
Yaru Liu, Ao-bo Wang, Nanyang Ye, 2026
[Paper]

We present V-CAGE, an agentic framework for autonomous robotic data synthesis that leverages foundation models to bridge high-level semantic reasoning with low-level physical interaction. By centralizing semantic layout planning and visual self-verification, V-CAGE fully automates the end-to-end pipeline for highly scalable robotic datasets.

Seeing enough: non-reference perceptual resolution selection for power-efficient client-side rendering
Yaru Liu, Dayllon Vinícius Xavier Lemos, Ali Bozorgian, Chengxi Zeng, Alexander Hepburn, Arnau Raventos, 2026
[Paper]

We propose a non-reference method leveraging the spatio-temporal limits of human vision to predict the lowest resolution that remains perceptually indistinguishable from maximum quality. This enables highly efficient, perception-guided client-side rendering on power-constrained devices.

SPEM-F: Accounting for Eye Motion in Image and Video Quality Metrics
Pontus Ebelin, Yaru Liu, Niklas Sanden, Dounia Hammou, Daqi Lin, Tomas Akenine-Möller, Rafal Mantiuk, 2026

We present SPEM-F, a novel preprocessing filter that models smooth pursuit eye motion to convert any image or video metric into a perceptual video quality metric. Validated on a new 240-fps dataset, it physiologically simulates visual system latency, significantly improving prediction accuracy for temporal rendering artifacts and fast motion.

M3ashy: Multi-modal material synthesis via hyperdiffusion
Chenliang Zhou, Zheyuan Hu, Alejandro Sztrajman, Yancheng Cai, Yaru Liu, Cengiz Oztireli
Proceedings of the AAAI Conference on Artificial Intelligence, 2025
[Paper]

This framework enables neural material synthesis utilizing hyperdiffusion to learn the distribution over material weights. It provides flexible generation guided by multi-modal inputs such as material types, text descriptions, or reference images.

Real-Time Scene Reconstruction using Light Field Probes
Yaru Liu, Derek Nowrouzezahrai, Morgan McGuire
I3D 2024, Poster
[Paper]

Our approach leverages sparse real-world images to generate multi-scale implicit representations of scene geometries. By introducing a novel probe data structure, we accurately capture depths to decouple rendering performance from scene complexity.
