Visualization is a multi-disciplinary field aimed at assiting others find insight in their data. Graph visualization, security visualization, and volume visualization all aim to address certain user tasks. These applications further drive the science and visiblity of visualization.
Research Highlights
Nematic Liquid Crystal Visualization
Nematic liquid crystals are a state of matter with many potential applications. But in order to develop this applications, visualization methods are needed to assist in understanding the tensor alignment properties and to detect and depict defects. This project aims to satisfy those needs.

Graph & Tree Visualization
Graphs and trees naturally represent relationships between concepts. Many types of information contain such relationships, and thus informative graph and tree visualization is very important. This research investigates different graph and tree visualization methods for a vareity of domain problems.

Security Visualization
Computer security experts must sift through and analyze an ever-growing and quickly changing amount of information in order to keep systems safe. This research program proposes a suite of visual analytic methods to assist these exports explore, identify, and act upon threats and anomalies.

Volume Visualization & Transfer Function Generation
Volume visualization is the process of creating depictions of 3-dimensional data such as CT-scans. An important part of this process is the generation of transfer functions—the function which determines what is visible and how it depicted. This research seeks to create more effective volome visualization and transfer function generation techniques.
