I am currently a researcher at Huawei Noah's Ark Lab, conducting research on foundation models and AI agent.

From 2018 to 2022, I spent four years at the Chinese University of Hong Kong (CUHK) to obtain my Ph.D. degree, under the supervision of Professor Guoliang Xing (IEEE Fellow). During Ph.D., my research interests lie in the Sensing and Computing for Edge AI Systems. I got my Bachelor degree from School of Physics, University of Science and Technology of China (USTC) in 2018.

When I have free time, I enjoy studying business models across various industries and researching how to invest based on fundamental analysis. Some of my random thoughts can be found in the 雪球专栏, 知乎专栏

Research Interests

Throughout my Ph.D., I conduct research on the Sensing and Computing for Edge AI Systems. My research involves the following three directions:

  • Sensor-Specific Data Processing
    I have been working on the data processing algorithms on a variety of sensors, including RGB-D cameras, IMUs, and mmWave radars. Applications include object detection, object tracking, activity recognition and vital sign sensing.

  • Machine Learning Algorithms for Real-World Data
    Due to the imbalanced data distribution, data insufficiency and domain shift, machine learning using the real-world data is highly challenging. I have been working on corresponding solutions on federated learning, long-tailed learning, few-shot learning and domain adaptation, etc.

  • High-Performance Inference on the Edge
    The deployment of the deep learning models on edge devices is the last mile of building an AIoT application. My studies aim to accelerate the on-device inference of neural networks via hardware-aware tensor program generation using both intra-operator and inter-operator optimizations.
