🚨 New CHI 2026 Workshop 🚨 PoliSim@CHI 2026: LLM Agent Simulation for Policy

🚀💫 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.

Happy to share that our paper has been selected for an ORAL presentation at #EMNLP2025 main conference! I’ll be presenting in person in Suzhou. See you there!

Happy to share that our paper has been accepted to #EMNLP2025 main conference!

🚨 New Preprint! 🚨 Smarter LLMs are more selfish. We show reasoning-enhanced models significantly prefer greed over cooperation. The more LLMs reason, the worse they cooperate. 👇 THREAD 👇 [Link to paper: arxiv.org/abs/2502.177... [1/n]

🚨 New Paper! 🚨 “Groups that communicate diverse information make wiser decisions.” Right? Not always—for LLMs, just like humans. We bring this scrutiny to AI by introducing the Hidden Profile paradigm to assess how multi-agent LLMs actually reason together. arxiv.org/abs/2505.115... [1/n]

😬In sims, 1/100 Asian-coded agents will join a protest if told they shouldn't. All 100 Black-coded agents will join anyway. New #Facct2025 paper led by @yuxuanli1225.bsky.social Actions Speak Louder than Words: Agent Decisions Reveal Implicit Biases in Language Models sauvikdas.com/papers/64/se...

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

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...

🔒 Our new #USEC2025 paper shows that by automating permission decisions based on prior decisions, we risk NORMALIZING privacy discomfort rather than reducing it. "Modeling End-User Affective Discomfort With Mobile App Permissions" Paper: sauvikdas.com/papers/60/se...

🚨 In our new #USEC2025 paper, we introduce a secure, physically-intuitive RFID tag that users actually trust. On-demand RFID: Improving Privacy, Security, and User Trust in RFID Activation through Physically-Intuitive Design 👉 Paper: sauvikdas.com/papers/62/se... #Privacy #AcademicSky #Security

🚀 Our paper has been accepted to #CHI2025! 🎉 arxiv.org/abs/2409.12000 As AI technologists and data workers increasingly enter the news industry, cross-functional collaboration with journalists is becoming essential. But how do these collaborations unfold in practice?

@hankhplee.bsky.social's MSR internship work is getting quite a bit of attention! Following a year where he was recognized with both a CHI Best Paper and a USENIX Security Distinguished Paper, it looks like I will one day be best known for being Hank's advisor :p

🚨Trapped by infinite scroll & autoplay on social media? Our TOCHI paper introduces a system that reduces distraction by 4x by suppressing these and other dark patterns. Purpose Mode: Reducing Distraction through Toggling ACDPs on Social Media Web Sites 📝 hankhplee.com/papers/purpo...

LLMs let bias slip out when acting as agents arxiv.org/abs/2501.17420

In this new pre-print, my student @yuxuanli1225.bsky.social outlines how language agents making shockingly biased decisions, even when their words seem "unbiased". Also, the latest models are better at hiding bias, but it still drives what they do. It's also his FIRST Ph.D. paper! Please boost :)

🚨 Advanced LLMs may sound unbiased—but it's a ruse. We show that demographically-informed language agents reveal stark, implicit biases in decision-making. New preprint: “Actions Speak Louder Than Words: Agent Decisions Reveal Implicit Biases in Language Models” 👉 arxiv.org/abs/2501.17420 [1/n]
