Dr. T.J.'s Research

Dr. T.J.'s research areas are at the intersection of scientific and information visualization. His goal is to make visualization techniques and systems more effective by improving interaction methods and visualization utilization. Towards this end, he focuses on visualization interfaces, visualization modeling, and applications such as volume, graph, and security visualization. The motto of his work is:

We do not make the visualizations you do; we make the visualizations you do better.

Research Projects

A list of Dr. T.J.'s research areas can be found below; more information (such as publication links, recent news) is presented for each topic in the subsequent pages. Complete lists of publications and funding are also available.

• Human Factors in Visualization

  This research program explores different human factors in visualization such as user interfaces, perceptual issues, etc. While new visualization techniques are neede to solve a user's tasks, those techniques are not useful without effective means for the user to utilize them.

• Visualization Fusion

  Scientific and information visualization have developed as two separate fields. While this approach has been beneficial, lessons from each community can be applied to the other to enhance them both. In addition, a science which approaches visualization as a unified field is needed for a better understanding of visualization as a whole.

• Web-based Visualization

  Visualization is often used in collaborative environments where peers may be distributed over vast geographic distances. In addition, data access may be restricted while visualization of that data may be open. These and similar issues drive the need for web-based visualization: visualizations which may be accessed uniformly, anywhere.

• Applications in Visualization

  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.

A research blog detaling advances in these and related research areas is also maintained.
