Augmented Reality
will revolutionize our everyday life

I’m passionate about researching, developing and deploying Computer Vision and Deep Learning algorithms, for making our world better through Self-Driving Vehicles, and Augmented-Reality applications. I received my PhD at Bournemouth University, UK, focused on Augmented Reality research with Computer Vision and Machine Learning. Before this PhD programme, I got my Master's degree from University College London (UCL) with distinction. My research focuses on Augmented Reality in surgical guidance and games with the common theme of applying novel computer vision technologies, e.g. SLAM (Simultaneous Localization And Mapping) and machine learning techniques, e.g. Deep Learning, to tackle the AR tracking, reconstruction and interaction problems.

Skills & Techniques

  • Multi-platform Programming

    I’m passionate about solving real-world problems with coding. I have more than 8 years multi-platform programming experience with C/C++, Python, Matlab and Golang in Windows and Linux.

  • Research

    I love research and always keep up with the latest research trend and paper. I have published 8 papers as the first author during my PhD including some of the most impactful journals and conferences such as IEEE Transactions on Medical Imaging (IF 7.81), Neurocomputing (IF 4.07), and IEEE International Symposium on Mixed and Augmented Reality (ISMAR), Eurographics (EG).

  • Computer Vision

    Computer Vision is one of the most impressive and fascinating technologies that I have learned and worked on. It is the door connecting the machine with our real world. So far, I have worked on many projects using computer vision, such as medical image processing, AR and Self-Driving. I have comprehensive knowledge and experience with computer vision algorithms in feature/object tracking, camera calibration, Structure from Motion (SfM) and Simultaneous Localization and Mapping(SLAM).

  • Deep Learning

    I am keen on deep learning and believe it's the key to many future technologies such as AR and Self-Driving. I have extensive experience using Caffe and Tensorflow for object classification (CNN), semantic segmentation(FCN, CRF-RNN) and reinforcement learning. I have completed and earned certificate of the Deep Learning Specialization coursera online course by Andrew Ng. [Certificate]
