Built the Visual Intelligence team from scratch. Directed research in Vision Transformers, multimodal large models, and industrial AI systems.

• Created Twins (NeurIPS 2021), CPVT (ICLR 2023), VisionLLaMA (ECCV 2024) — influential Vision Transformer architectures; VisionLLaMA introduced auto-scaling 2D RoPE for LLaMA-style vision backbones
• Built MobileVLM, a compact VLM designed for real-time on-device deployment; reproduced LLaMA 7B from scratch
• Open-sourced YOLOv6, a widely used industrial object detection framework; developed QARepVGG to address quantization challenges in RepVGG-style deployment
• Shipped 3D perception for autonomous delivery vehicles and drones, reducing annotation and serving costs

Founded Xiaomi’s AutoML team and produced a series of influential neural architecture search works.

• FairNAS (ICCV 2021), FairDARTS (ECCV 2020), DARTS- (ICLR 2021), FALSR — establishing new standards for fair and robust architecture search
• Won 2nd place in Xiaomi’s first “Million Dollar Prize” (Automated Neural Network Design)
• FALSR super-resolution algorithm personally endorsed by CEO Lei Jun

• Core contributor to “Complex Power Grid Autonomy — Collaborative Automatic Voltage Control” project
• Contributed 20 invention patents; awarded National Science and Technology Progress First Prize (2018)

• Large-scale data analytics and machine learning solutions at IBM China Research Lab
