Graphics, Visualization, and HCI

graphic visualizationIncreasingly present in daily life, interactive technology needs to be designed effectively to avoid adverse consequences such as loss of life, productivity loss, and negative experiences. To solve these monumental problems, our researchers invent, implement, and study new forms of interaction, automation, and visualization techniques.

Our work targets problems in social computing, design and creativity, decision making, intelligent systems, and cognitive modeling. For example, we study the transparency of algorithms controlling social media feeds, the use of robotics in domestic environments to support aging in place, and the application of crowdsourcing for creative work. Working at times with companies like Microsoft, Intel, Google, and Facebook, our research synthesizes knowledge from machine learning, psychology, design, and the learning sciences. In graphics and visualization, our research includes modeling and animation of natural phenomena, computational topology, graphics hardware utilization, image-based rendering, implicit surfaces, procedural texturing, and surface parameterization.

Graphics, Visualization, and Human-Computer Interaction Research Efforts and Groups


The Graphics seminar meets weekly to present and discuss recent research papers in computer graphics. Course credit of one hour is available, but requires attendance at the seminars and presentation of one paper. Announcements of upcoming presentations are made to, and you can subscribe to that mailing list.

The HCI seminar brings in emerging and established intellectual leaders in the field of human-computer interaction to present their latest research findings and visions. It also provides a lively forum for our students to practice conference, defense, and job talks and for colleagues to seek collaborators. Subscribe to the mailing list for the seminar.

Google’s Chrome Hackers Are About to Upend Your Idea of Web Security

November 4, 2016  

Wired - Coming soon to Chrome: revamped security warnings, thanks to the Security Team led by “Director of Chromeland Security” Parisa Tabriz (BS ’05, MS ‘07). “In our impatient moments, we just want to mark everything as insecure,” Tabriz says. “A huge fraction of the web isn’t HTTPS, and that’s embarrassing to me. It’s not going to solve itself.”
