I’ll be joining the Institute of Human-Centred Computing – hcc.tugraz.at/ – and look forward to new collaborations with the fantastic team there.

I’ll also stay closely connected to Utah, continuing my work with the amazing team at the SCI Institute and the Kahlert School of Computing.

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 CHI 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.

It’s the time of the year when students accepted to graduate programs make decisions on where to go, while others might still be anxiously waiting to hear back. Unfortunately, the grad admissions process is opaque, so I’ve written a post that gives background: vdl.sci.utah.edu/blog/2025/04/

Can you run a think-aloud study via crowdsourcing? Yes you can! We used reVISit for running and analyzing online TA studies. And yes, online participants do actually speak, though they’re more critical than lab participants. Check out the CHI paper: vdl.sci.utah.edu/publications/ #datavis #chi2025

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-studie

Thank you!

Different visualizations - a map, a pie chart, a bar chart, using black and white patterns.

The Internet is mostly shit these days, but every once in a great while I stumble across an incredible, passion-project website.

This one is hand-animated weird art and it is worth your time as a fun decompressing thing in between your doomscrolling sessions.

I don't even know what hashtags this deserves, so it's not getting any. Boost to your friends!

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

ReVISit 2.0 (revisit.dev) has reached several exciting milestones recently:

📁 Define an **entire** experiment in a single file-- (visualizations, data, study sequence, questionnaires, etc.)

🛫 Pilot and iterate on the experiment within a notebook environment.

📈 Test data collection and prototype your analyses in the same notebook!

See it in action in this clip, where we replicate a correlation perception experiment in ~160 lines of Python.

it's worth repeating that trump's executive order against DEI was actually against DEIA … the A stands for Accessibility, a very different issue. Accessibility means coding software and documents properly so everyone can use them, instead of making them wrong. Almost nobody is against accessibility

As someone who is totally blind, the Fediverse is the only place where I have ever been able to follow people such as photographers, artists, or even those who post pictures of their cats or the food they ate. The reason is that most of them use alt text. They take the time to describe the images that my screen reader can't recognise. Some write the descriptions themselves, and others use tools such as altbot. Some worry that their descriptions aren't good enough, especially when they are new at this. Let me assure you, not only are they good enough, they are extremely appreciated! If the rest of the world thought as you did, it would be a much better place. Don't hesitate to ask if you're unsure of something, but never think that we don't notice your effort.
