Just arrived in Bergen for CSCW, where I'll present Venire! Venire is a Reddit moderation tool that uses an ML model trained on mod decision histories to identify controversial cases. It preempts inconsistent decision-making by flagging these cases for multi-mod review dl.acm.org/doi/10.1145/...

LLM safety work often reasons over high-level policies (be helpful & polite), but must tackle on-the-ground cases (unsolicited money advice when stocks are mentioned). This can feel like driving on an unfamiliar road guided by a generic driver’s manual instead of a map. We introduce: Policy Maps 🗺️

Social media feeds today are optimized for engagement, often leading to misalignment between users' intentions and technology use. In a new paper, we introduce Bonsai, a tool to create feeds based on stated preferences, rather than predicted engagement. arxiv.org/abs/2509.10776

We are organizing a workshop on Algorithmic Collective Action at NeurIPS this year. As AI continues to concentrate power, we will meet in San Diego (Dec 6 or 7) for critical conversations on user coordination, labor, data protection, and community advocacy. Submissions due August 22. #NeurIPS2025

Last day of #ACL2025NLP but there's still lots to do: attend the #WikiNLP workshop, where we explore how NLP and wikipedia can help each other! We have amazing keynotes, discussions with Wikipedia editors, a panel + posters! Details: meta.wikimedia.org/wiki/NLP_for... Join us in room 2.31!

My team is organizing a workshop on information disorder at the CSCW conference (Oct 18, Bergen, Norway). We aim to convene scholars committed to understanding mis & disinfo, scams, online hate, etc. Applicants should submit 2-6 page position papers by Aug 1: cscw2025infodisorder.netlify.app

Prompting is our most successful tool for exploring LLMs, but the term evokes eye-rolls and grimaces from scientists. Why? Because prompting as scientific inquiry has become conflated with prompt engineering. This is holding us back. 🧵and new paper with @ari-holtzman.bsky.social .

Thrilled to share that I’ve successfully defended my PhD dissertation and I will be joining MIT as an Assistant Professor starting Fall 2026, with a shared appointment between Sloan and EECS! I will be recruiting 1-2 PhD students this upcoming cycle. Consider applying to MIT EECS!

Another week, another research ethics controversy. TL;DR Researchers released a public dataset of 2B+ messages from 4M+ users on 3k+ "public" Discord servers. Usernames/IDs are anonymized. But let's unpack this one... 🧵 www.404media.co/researchers-...

Somewhat oddly, the Trump regime's initial moves to cut science funding went very broad. This is catalyzing solidarity & advocacy around the value of science (see comms featuring cancer cures & tech innovation). But their next move may be to try to drive a wedge b/w "good science" & "bad science".

Groups use processes to make decisions. But normal people with no training will usually run a bad process. When you just perform how you think meetings are supposed to work, without training, your meetings will be boring or bad. AND, big secret: when everyone's trained, meetings feel good.

Serving as the Student Volunteer Co-Chair at #CHI2025 @chi.acm.org has been an incredible experience! A huge thank you to the 200 student volunteers who worked tirelessly behind the scenes to help make the conference a success. Looking forward to seeing you all next year in Barcelona!

☀️ Our amazing team of student volunteers is all set and excited for the conference kickoff! #CHI2025

📢📢📢 Second for Contributions! Join us at the 2nd WikiNLP Workshop on NLP for Wikipedia, co-located with #ACL2025 in Vienna. We welcome both in-person and virtual attendees, and have both archival and non-archival tracks! 🗓️ deadline: April 30 Details: meta.wikimedia.org/wiki/NLP_for...

I would love to never see the phrase "little is known about" in a paper ever again. (1) Most of the time the authors are far more confident about that statement than they should be. (2) There are lots of things we know little about because no one cares. Just not knowing isn't a good motivation.

Do you make custom feeds on Bluesky? We'd love to hear about your experiences as part of a research project at @uofwa.bsky.social @socialfutureslab.bsky.social ! Come chat with us for 45 mins and get $20 gift card. Express your interest here: forms.gle/CtoZTwCovTv8....

AI research often aims to generate Wikipedia-like content, but Wikipedia’s success lies in the underlying processes and infrastructures that enable human collaboration. Rather than just mimicking content, we should use AI to support human collaboration. Our Wikibench paper is one such example:

"When a complex system is far from equilibrium, small islands of coherence in a sea of chaos have the capacity to shift the entire system to a higher order." Iya Prigogine, Noble prize-winning chemist

Check out our latest work on steerable alignment! We improve on a typical in-context learning approach with semantic retrieval by proposing metrics that instead select examples that best exemplify a group's shared values, enabling inference-time alignment to a particular group. ➡️

In-context learning can be an effective way to conduct value alignment of LLMs through examples, but when there are multiple pluralistic groups, are the best examples for one group also the ones for another? We explore this in our paper 🌟SPICA🌟 (🧵1/9)

How can we help communities collaboratively shape policies that impact them? In our #CHI2025 paper, we present PolicyCraft, a system that supports ✨collaborative policy design✨ through case-grounded deliberation. (🧵/11)

Book announcement: with Melissa Valentine, we are publishing "Flash Teams: Leading the Future of AI-Enhanced, On-Demand Work." It's a leadership book synthesizing a decade of Stanford research on how computing, online platforms, and AI reshape teamwork. Coming October from @mitpress.bsky.social!

I’m honored to receive the Presidential Fellowship from @carnegiemellon.bsky.social's K&L Gates Initiative and to speak at next week's GenAI conference! I'll share how we build systems that empower people to shape AI through collaborative, deliberative, and democratic processes.

In Taiwan, years back, some civic hackers created the Gov0 campaign (or g0v) in which they got the domain name g0v.tw (it's a zero in the middle) and created alternatives to every gov website of what they would do if they were in charge. Anyone could see the plans by replacing the o with the 0.

Am reminded of this CHI paper about the problem with crowdsourcing fact checking to users - it showed that the partisanship of users was more predictive of what gets challenged than the actual content. :-/ dl.acm.org/doi/10.1145/...

Imagine if you could use the programming work of others to solve problems, translate text, or answer complex questions — all without needing to know how to code. Wikifunctions makes this possible by creating a global library of reusable tools, or functions, that anyone can use and improve. 🧵⬇️ (1/7)

I've been thinking about in-context learning for nearly 3 years. While there is still plenty I don't fully understand, five papers have--to a very large extent--shaped my perspective on it, and I believe everyone should read them.
