His Major research contribution includes:

1) Scalable Large Scale Scientific Visualization: Scientists are generating ever-growing scale of data with supercomputers in this big data era. Visualization has been increasingly important for analyzing, understanding, and revealing insights in data. Our research interests generally involve in scalable visualization and analysis of large scientific data. We largely employ and develop parallel and scalable methods to visualize and analyze data on cutting-edge HPC platforms. Feature scalability. We meet the challenge of the new data and needs in scientific research, e.g. increasing number of variables and ensemble constituents, coupled analysis of scalar and vector attributes, etc. Our research focus on multivariate, multi-valued, and ensemble flow data, which consists of both scalar and vector attributes in the context of our studies. Alternative to traditional flow visualization methods which have been studied for decades, we emphasize on the scalable analysis of indirect and multi-faceted features. We also extensively use both Eulerian and Lagrangian method for the flow data analysis from multiple perspectives. More recent work in this direction involves developing new approaches to take the advantage of data access pattern to reduce the I/O cost and improve the performance in load balance.

2) High-dimensional data Visualization: High-dimensional data refers to data items with multiple attributes. The key task is to simultaneously visualize and relate multiple attributes, in order to reveal data patterns as well as attribute relationships. Many visualization techniques have been proposed to fulfill the task, such as scatterplot matrix, parallel coordinates, etc. Yet, these are not perfect solutions, not to mention the many unexploited research problems and application fields. Regarding all the potentialities, we start the series of high-dimensional visualization researches in the PKU Vis lab. We dedicate to improve traditional techniques, propose new methods, and explore untouched application fields.

3) Urban Visualization: We focus on trajectory data. Effective visualization and analysis of such data may help us better understand the urban transportation system, find out strategies to reduce the number of accidents and traffic jams, thus ensuring people's safety, facilitating people's trip and elevating the economic efficiency. In a series of projects, we studied several aspects with trajectory data, including: traffic density, traffic jams and traffic pattern correlation.

4) New visualization methods: In this direction, we developed series of approaches of

a) Map metaphor to visualize information diffusion and event development on social media. We developed methods called D-Map and E-Map to achieve such goals.

b) Novel visualization authoring tools. One major obstacle to prevent the wide usage of visualization by public users are the high learning curve of coding. We developed a few systems to construct new visualization (iVisDesigner) or argument new interaction on existing visualization (Interaction+) without coding efforts.
