After an incredible decade at the University of Utah, I’m happy to share that I’ll be returning to my alma mater, TU Graz, this fall as a Professor of Human-Computer Interaction.
I’ll be hiring a PhD student and a PostDoc in Graz—if you're interested in HCI and visualization get in touch!

Going to #CHI2025 in Japan? Interested in running user studies?
Sign up for our virtual CHI 2025 course that teaches you how to use reVISit, a new, open-source user study tool reducing the tedium of study design. Come learn through some practical examples.

How can we use black-and-white patterns in visualization? If you have visualization design experience, we’d love your input! We’re running a short study (less than 20 minutes) where you’ll experiment with designing patterns for a chart.
Please participate here revisit.dev/replication-...

reVISit 2.0 Highlight: reVISit now supports Vega and Vega-Lite stimuli. You have the freedom to plug in Vega JSON configurations inline, or as a file. You can leverage interaction and reVISit's provenance tracking and interaction replay feature as well, with no extra effort. revisit.dev #datavis

I wonder what percentage of wasabi is actually eaten vs thrown out. If I'm anywhere close to average it can only be 10% at most...

A cool idea is what Segel & Heer call "the Martini Glass Structure" where a visualization begins with a scripted story, but then opens up free exploration.
