Hi, there! I am Leo, and I live in Toronto, Canada. I am soon completing my PhD study at VisLab of HKUST in 2024.
My primary research focuses on data visualization and addressing misleading information. Before my PhD study, I had completed my MPhil in Computer Science at HKUST and BSc. Computer Science at CUHK and worked as a Software Engineer for several years.
I am passionate about the world we live in, where programming computers opens up incredible possibilities. With the vast amounts of data available today, we can achieve things that were once unimaginable and transform the way 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 takes in 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!
Data visualizations are powerful tools for gaining insights from data but there is also potential to be misled by visualizations. My PhD thesis investigate this negative potential of data visualizations and develop guardrails to prevent this negative impact. Three published works on this topic constituted the main theme of my PhD thesis.
[Misinformed by Visualization: What Do We Learn From Misinformative Visualizations?]
[Why Change My Design: Explaining Poorly Constructed Visualization Designs with Explorable Explanations]
[How Good (Or Bad) Are LLMs in Detecting Misleading Visualizations]
A computer vision system that collects and analyzes food tray images to provide analysis on food consumption and waste patterns in the canteens at HKUST. [Project]
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]
Learning Vis Tools is a series of data visualization tutorials covering a wide range of visualization tools covering GUI, Python and Javascript. [Presentation@VIS19] [GitHub]
100 Vis Challenge is an on-going challenge for myself to draw 100 beautiful visualizations with public datasets. [Observable]
VisMOOC+ hosts video, collects clickstream data and helps instructors and students to improve teaching and learning through visual analytics. [GitHub]
aimole is a competition platform for game playing AI. Students compete on the leaderboard by writing bots to play against each other. We have developed two games, Othello and 2048. [GitHub]
codeSubmit is a programming assignment online judge. Students can directly do coding on web, run their code and get feedback immediately. [GitHub]
Rumours Hub is a maching learning project to extract information from football transfer news using techniques learned from Andrew Ng's Machine Learning Course on Coursera. [Demo]

I continue my study in data visualization as a PhD student. I published a series of papers on misleading visualizations on various top-tier journals of the data visualization research community. Besides, we delivered several large scale visual analytics projects related to learning analytics and food waste analytics.
I started my postgraduate study at HKUST and research on data visualization. During my MPhil study, I received multiple awards including best short paper honorable mention award, best poster award, and best teaching assistant award.
VisLab is a research group lead by Prof. Huamin Qu. We developed and deployed the 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. We built scalable and reliable data acquisition backend to support the social media and inluencer analysis.
With Dr. Wong Tsz Yeung, we created and taught an online course of hundreds engineering students at CUHK, including course materials (gitbook), assignments (supported by codeSubmit) and project (supported by aimole).
Mobigator is a healthcare management software consulting firm. We delivered a communicable disease information system and deployed to the Centre for Health Protection of Hong Kong Government.
I enjoyed the best computer science undergraduate education in Hong Kong. The strong computer lab culture provided the best learning environment and resources to me and my peers.
I read a lot. I like the feeling of knowing more about this world.
