Hi, there! I am Leo, live in Hong Kong. I am now doing my postgraduate study at VisLab of HKUST, on data visualization. Previously, I had completed my BSc. Computer Science at CUHK and worked in the industry as Software Engineer for a couple of years.
I am enthused by the world we are living in. It's an exciting era with abilities to program computers. Especially with abundant amount of data, we can do things that seem impossible before. It also changes the ways we approach problems.
I love data visualization. With the gigantic amount of data collected, we cannot see the truth beneath it without visualizing it. Data visualization incorporates a broad range of knowledge to let us see in the ocean of data. It is both computationally technical and psychologically humane while the painting is artistically pleasing.
Let's visualize the world!
Bad Vis Browser is a collection of bad visualizations collected from the Internet. I labeled each visualization and put them into a gallery. [Dataset] [GitHub]

I continue my study in data visualization as a PhD student. I have learned a lot from the visualization community, and determined to contibute to the community, as a researcher.
After a year working as research assistant, I decided to start my postgraduate study with primary focus on data visualization and any related field of research.
VisLab is a research group lead by Prof. Huamin Qu. I am responsible for developing VisMooc project, an exciting project on data visualization for all aspects of Massive Open Online Course.
Lamplight Analytics is a startup collects data from social media, analyses and spots influencers. I am responsible for building scalable and reliable data acquisition backend to support the analysis.
I am the engineer of the online course taught by my former teacher Dr. Wong Tsz Yeung, including course materials (gitbook), assignments (supported by codeSubmit) and project (supported by aimole).
Mobigator is a healthcare management software consulting firm. I am responsible for the software development of communicable disease information system, deployed by the Centre for Health Protection of Hong Kong Government.
I read a lot. I like the feeling of knowing more about this world.
