📣 New paper alert 📣 What if AI agents' biggest strength is also their biggest risk? "The Perils of Agency: How Developers Perceive, Prioritize, and Address Risks in Agentic AI Products" (#AIES2026) 📑 hankhplee.com/papers/aies2... 🧵1/9

Excited to be in Barcelona 🇪🇸 next week for #CHI2026 and share one full paper and one workshop paper on privacy, GenAI, and critical thinking.

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.

📣 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...

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]

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.

@cylab.bsky.social wrote a great article on @hankhplee.bsky.social's #chi2025 paper on Purpose Mode. He presented it today and did a great job! PurposeMode reduces distraction on social media from 28% -> 7%. You can use it, too! It's open source :) cylab.cmu.edu/news/2025/04...

Purpose Mode helps social media users stay focused on their desired tasks

A CMU research team has developed Purpose Mode — a browser extension that allows users to “toggle off” Attention Capture Damaging Patterns (ACDPs) while using social media platforms.

How does using GenAI tools reshape knowledge workers’ critical thinking? Our #CHI2025 paper studied 319 knowledge workers to dive into this question. w/@advaitsarkar.bsky.social @levlevlev.bsky.social Ian, Sean, Richard, Nick @msftresearch.bsky.social @hcii.cmu.edu www.microsoft.com/en-us/resear...

@yuxuanli1225.bsky.social has been producing great work since day one of his PhD. Can’t wait to see where his brilliant work leads next!

We just found out that @yuxuanli1225.bsky.social 's paper was accepted to #FAccT2025 A true testament to his hard work and determination!

I'm absolutely thrilled to see my recent CHI paper go viral! I’m humbled by all the support and grateful for the thoughtful critiques. Critical thinking in the Generative AI era is more important than ever — stay tuned for more insights soon!

Microsoft's own research confirms something that was already pretty obvious: relying on a text generating machine to come up with answers erodes critical thinking, and is a method favoured by those who never liked doing critical thinking in the first place advait.org/files/lee_20...

📣 New paper Privacy harms can seem small in isolation. Viewed in aggregate, however, we realize how creepy surveillance capitalism can be. Unfortunately, these harms go unreported, blurring aggregate impacts. Our #CSCW paper explores how to fix that: sauvikdas.com/papers/56/se... #AcademicSky

I created a starter pack for researchers who work at the nexus of HCI & cybersecurity / privacy here. Please do let me know if you would like to be added to the list!I'm sure I've missed many folks. go.bsky.app/RGsu5jn
