About

Ziyu Jiang is a Senior Researcher in the Media Analytics Department at NEC Laboratories America in San Jose, CA. He earned his Ph.D. in Computer Science from Texas A&M University, where his doctoral work explored advanced methods in deep learning and visual understanding, laying the groundwork for his contributions to large-scale AI systems.

At NEC, Dr. Jiang’s work spans two core areas: autonomous driving and robotics. On the autonomous driving side, he focuses on building a simulator—a digital twin of the real world—to train and validate autonomous driving algorithms. On the robotics side, he is developing an agentic system that enables advanced robot deployment and self-evolution.

Drawing on his expertise across neural rendering, diffusion-based generation, 3D reconstruction, robotics, and agentic systems, Dr. Jiang’s innovations play a central role in NEC’s Autonomous Driving Simulation and Embodied AI initiatives. His work enables the automatic construction of photorealistic, controllable driving simulations, substantially reducing the cost of validating autonomous driving algorithms and ensuring their safety in long-tail scenarios. He is also taking on an increasingly important role in NEC’s robotics development.

Projects

Multimodal LLMs for AI DevOps

Overview: Our AI DevOps pipeline builds a high-fidelity digital twin of sensor data which allows for self-improvement of deployed models. We leverage our foundational vision-language models to automatically determine issues in currently deployed AI, pseudo-label or simulate training data, develop models with continual learning and use an LLM-based verification over diverse scenarios.


Neural Rendering and Diffusion for Simulation

Overview: Our simulation framework utilizes advances in neural rendering, diffusion models and large language models to automatically transform drive data into a full 3D sensor simulation testbed with unmatched photorealism.


Robust and Unbiased Face Recognition

Overview: Our face recognition methods achieve high accuracy on competitive public benchmarks through the use of universal representation learning techniques that leverage very large-scale datasets, with robustness to variations such as occlusions, blur, lighting or accessories.

Teaching AI to Edit Driving Scenes It Has Never Seen with HorizonWeaver

Our HorizonWeaver software edits driving scenes with instruction-guided AI, adding traffic, changing weather, and generalizing to unseen roads, all while preserving the safety-critical details that keep autonomous vehicle testing honest.

When Video AI Gets Physics Wrong, the Consequences Are Real

Video generation models can look physically convincing while getting the physics completely wrong. PhyCo, new research from our Media Analytics department, introduces continuous, controllable physical properties to video AI, allowing practitioners to specify friction, bounce, and force.

HorizonForge: Driving Scene Editing with Any Trajectories and Any Vehicles

Controllable driving scene generation is critical for realistic and scalable autonomous driving simulation, yet existing approaches struggle to jointly achieve photorealism and precise control. We introduce HorizonForge, a unified framework that reconstructs scenes as editable Gaussian Splats and Meshes,

HorizonWeaver: Generalizable Multi-Level Semantic Editing for Driving Scenes

Ensuring safety in autonomous driving requires scalable generation of realistic, controllable driving scenes beyond what real-world testing provides. Yet existing instruction guided image editors, trained on object-centric or artistic data, struggle with dense, safety-critical driving layouts. We propose

LangDriveCTRL: Natural Language Controllable Driving Scene Editing with Multi-modal Agents

LangDriveCTRL is a natural-language-controllable framework for editing real-world driving videos to synthesize diverse traffic scenarios. It represents each video as an explicit 3D scene graph, decomposing the scene into a static background and dynamic object nodes. To enable fine-grained editing and

PhyCo: Learning Controllable Physical Priors for Generative Motion

Modern video diffusion models excel at appearance synthesis but still struggle with physical consistency: objects drift, collisions lack realistic rebound, and material responses seldom match their underlying properties. We present PhyCo, a framework that introduces continuous, interpretable, and physically
