CARLOS SCHEIDEGGER BLOG COURSES TALKS CODE VIS WRITING PAPERS ABOUT CV

I'm a software engineer at RStudio, (and an associate professor on leave in the Department of Computer Science at the University of Arizona). I work in large-scale data visualization and data analysis. Before coming to sunny, beautiful Tucson, I worked at AT&T Research in New York.

Interactive visualization is crucial in understanding, exploring, and presenting data, but data scale can present serious barriers for effectiveness and adoption. I study these barriers and design solutions to remove them. My work ranges from theoretical to practical; from designing solutions specifically for particular domains to designing general infrastructure for large-scale visualization.

Since joining UA, I have worked in a number of projects here, including support for interactive browsing of synteny data at CoGe, and building up interactive visualization infrastructure for the ANTARES project. If you're interested in our work, you should also take a look at the webpage of the HDC Lab which I cofounded with my colleagues, Josh Levine and Kate Isaacs.

(I'm trying something different for writing, instead of a blog.)
