The Humans, Data, and Computers Lab

Software Papers People Contact

At the HDC Lab, we study how computer science interacts with human experiences, at all levels. We specialize in novel algorithms for interactive visualization and exploratory data analysis. This ranges from creating mathematical foundations for the evaluation of visualization designs, to novel data structures and systems for interactive data analysis at scale, to novel ways to characterize data-driven discrimination, to topological analysis in visualization.

When human concerns and our modern technological society overlap, we strive to advance computer science in order to help people lead better lives.

We are part of the Department of Computer Science at the University of Arizona’s College of Science.
