Leo Yu-Ho Lo

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!
