Excited to be heading to Barcelona for #CHI2026 to host our workshop PoliSim: LLM Agent Simulation for Policy! This year, we’ve seen incredible interest from researchers across HCI, NLP, CSS, and Policy. We accepted 25 outstanding papers, with 5 selected as Best Paper nominees.

The overleaf git project for one of my #uist2026 submissions was assigned a uuid starting with "67". I believe this lets me mine the latest block on the gen alpha blockchain using the "Proof of Relevance" protocol. Who should I speak with about this

Will AI become a confirmation bias machine? AI can be a powerful tool for truth-seeking. Yet, people might prefer to use AI to confirm their pre-existing beliefs, and features of AI systems (eg sycophancy) may make AI effective at justifying what people want to believe. osf.io/preprints/ps...

Really excited that “Privy” received a CHI ’26 Honorable Mention Award 🏅 Privy is part of my PhD work on AI privacy: understanding AI privacy risks, studying why they’re hard to address in practice, and building tools that help product teams act on them.

I am working on a UX audit agent for my company (fuguux.com/). I passed in the output of our audit agent into Claude code for my personal website and...voila, a refreshed and much better site. Surprised it worked! Before -> after sauvik.me

An exciting development: Privy was recognized with a best paper honorable mention at #chi2026! Congrats to the whole team, including: @hankhplee.bsky.social @kyzyl.me @jodiforlizzi.bsky.social

SCOOP: An internal DHS document obtained by 404 Media shows for the first time CBP used location data sourced from the online advertising industry to track phone locations. This surveillance can happen through all sorts of apps, such as video games, news apps, weather trackers, and dating apps.

Honored to be named Privacy co-chair of ACM's U.S. Technology Policy Committee with @benwinters.bsky.social On that note: please read USTPC's statement discouraging adtech vendors from sharing personal data with DHS/ICE.

Can LLMs really serve as "crash dummies" for security & privacy testing? We put this assumption to the test. 🚨New preprint 🚨: "How Well Can LLM Agents Simulate End-User Security and Privacy Attitudes and Behaviors?" 👇 THREAD 👇 [Link to paper: arxiv.org/abs/2602.184... [1/n]

New statement from the ACM U.S. Technology Policy Committee on AdTech & DHS privacy/security: computing experts urge stronger safeguards around government use of advertising-tech data collection. #Privacy #Security #TechPolicy acm.org/binaries/con...

🚨New paper🚨 We spent a year working with emergency preparedness policymakers to answer a simple question: can LLM agent simulations actually help real institutions make better decisions? The answer is yes—but perhaps not how you'd expect. 👇 THREAD 👇 [Link to paper: arxiv.org/abs/2509.218... [1/n]

📣 New at #CHI2026 People share sensitive things “anonymously”… but anonymity is hard to reason about. What if we could quantify re-identification risk with AI? How should we present those AI-estimated risks to users? Led by my student Isadora Krsek Paper: www.sauvik.me/papers/70/s...

📣 New at #CHI2026 Developing a new AI product? How would you figure out what are the privacy risks? Privy help non-privacy expert practitioners create high quality privacy impact assessments for early-stage AI products. Led by @hankhplee.bsky.social Paper: www.sauvik.me/papers/69/s...

Sounds like a great opportunity for anyone building a spring 2026 schedule right now! Hey @cmu.edu students, check out this HCII special topics course "Building Technologies for the Resistance." 👀 hcii.cmu.edu/course/speci... #privacy #cybersecurity #ethics #TechEthics #SurveillanceCapitalism

I'm fortunate to be able to teach my new class on "Building Technologies for the Resistance" next semester. If you're a CMU student, consider enrolling! This will be a collaborative, project-based class where you'll get to prototype resistance technologies.

I am pleased to say that I submitted the last of my dissertation work for publication! This work was a long-term goal starting with a Mozilla grant I applied for in my first year of PhD. Since then, I’ve learned a lot and hope that what I contributed will be useful to the community.

Gave a talk at PGH TechFest on The Promise and Perils of AI for Products. I summarize capabilities of AI today, challenges (trust, explainability, human agency), and recommendations.

🚀💫 I’m on the job market for academic (tenure-track) and industry research positions! 👋I am a Postdoc Fellow at @hcii.cmu.edu working at the intersection of human-AI interaction, cognitive science, responsible AI, design, and social computing. I earned my PhD from @gtresearch.bsky.social in 2024.

Excited and grateful to share that I’ve been named a Presidential Fellow by @cylab.bsky.social ! Endless thanks to my advisors @sauvik.me and Jodi Forlizzi, and all my collaborators for their constant inspiration as we work toward shaping the future of privacy-preserving AI.

Congrats to my student @hankhplee.bsky.social for being recognized as one of the 2025 CyLab Presidential fellows! cylab.cmu.edu/news/2025/1...

Two spuddies will be at #CSCW2025: @yuxiwu.com will present our work on designing citizen harm reporting interfaces for privacy (and is on the job market!). Isadora Krsek will present our work on user reactions to AI-identified self-disclosure risks online.

Honored to be one of the recipients of the Google Academic Research Awards this year! @alan-ritter.bsky.social and I will further our work on exploring how AI can be used to help users make safe disclosure decisions online. research.google/programs-an...

tl;dr: i'm on the academic job market; say hi at #CSCW2025! i'm a distinguished postdoc fellow at northeastern studying how tech's deep entanglements into society have caused concrete harms to people and changed what privacy fundamentally means (is it dead? is it recoverable? how? 😨) yuxiwu.com

I'm on the job market looking for CS/ischool faculty and related positions! I'm broadly interested in doing research with policymakers and communities impacted by AI to inform and develop mitigations to harms and risks. If you've included any of my work in syllabi or policy docs please let me know!

#chi2026 reviewing season is here! Friendly reminder that it is possible to write thoughtful reviews without nitpicking and without it taking a lot of time. I've actually completed my seven 2AC reviews already. Some (updated) tips I wrote about this: sauvik-das.medium.com/a-quick-gui...

📣 Accepted to #AIES2025: What do the audio datasets powering generative audio models actually contain? (led by @willie-agnew.bsky.social) Answer: Lots of old audio content that is mostly English, often biased, and of dubious copyright / permissioning status. Paper: www.sauvik.me/papers/65/s...

🔐 New #UIST2025 paper by @kyzyl.me Imago Obscura uses #vision #language #models to understand user #privacy concerns, improve their awareness of image privacy risks, and their ability to address these risks. 📜: sauvik.me/papers/66/se... 🔗: cmu-spuds.github.io/imago-obscura/ #PrivacySky

Honestly, now I want to write a piper titled: "[mention a specific relevant paper by them]"

How does "AI search" differ from standard web search? Can you trust it? I spoke to Jon Reed at CNET about this: www.cnet.com/tech/service...

I've been receiving a new kind of email lately: people who GPT has convinced to email professors in order to get their "deeply insightful" conversations w/ GPT published. It's a weird confluence of AI sycophancy + human loneliness and delusions of grandeur.

Usability is like security: if you don't design around it from the very start, when you try to patch it on, unless you get lucky, you'll discover all kinds of architectural commitments that make it really hard, and you'll always play catch-up.

As of today, I am officially Associate Professor* at @hcii.cmu.edu. Surreal — I was out of my depth when I started. Couldn't have done it without my incredible students — the true brains of the operation — and the support of my mentors. Thank you all! * not yet tenured, because CMU

new paper incoming at USENIX Security 2025 📬 "Navigating Security and Privacy Threats in Homeless Service Provision" really grateful to have worked with @hongshen.bsky.social, Fei Fang, and a team of amazing undergrads and community collaborators on this project yuxiwu.com/pubs/sec25_h...
