About
The real voyage of discovery consists, not in seeking new landscapes, but in having new eyes.
--Marcel Proust
Research Interests

My primary research interests lie in the field of visualization and computer graphics. My broad vision is to invent novel visualization techniques to empower people in all scientific communities to explore, understand, and interpret the vast amount of data that result from physical acquisition and simulation. I am currently working on developing strategies and methods to address effective and efficient visualization.

 
High Fidelity Visualization
In high fidelity visualization, the goal is to develop algorithms that can deliver artifact-free visualization while achieving efficiency and retaining a maximum amount of information residing in the data.

Illustrative Visualization
Illustrative visualization explores the power of illustrations to effectively convey information by omitting or simplifying unimportant details while enhancing the most significant features or exposing hidden features that are important.

Explorative Visualization
In explorative visualization, the goal is to incorporate user into the data exploration process. Recent advances in input device technologies have brought opportunities for revolutionizing the interface and increasing the user's role in visualization. The main aim here is to equip the user with an intuitive sketch-based interface to perform difficult visualization tasks and to achieve a better understanding of complex phenomena.
