2024 marks the official launch of the Human-AI Collaboration Lab, so I wrote a one page letter to introduce the lab, share highlights, and begin a lab tradition of reflecting on the year and sharing what we're working on in an annual letter to share with friends and colleagues.

Excited to see our paper out now in Nature Machine Intelligence ! 🌟 We study the gap between what LLMs know and what users think they know, and show how tailored explanations can help bridge this gap. Read more here: nature.com/articles/s4225…

Our paper: Decision-Point Guided Safe Policy Improvement We show that a simple approach to learn safe RL policies can outperform most offline RL methods. (+theoretical guarantees!) How? Just allow the state-actions that have been seen enough times! 🤯 arxiv.org/abs/2410.09361

Can emotion regulation interventions spread from treated to non-treated people in a group? We examine this question in a paper published in Nature Communications, led by Michael Pinus & Yajun Cao. nature.com/articles/s4146…

🎙️➡️📝I build a minimalistic Python library for transcribing speech to text using the Whisper API because I found the existing apps a bit too feature rich (and expensive) for my taste. Sometimes, you just want a simple tool that does one thing really well.

Super cool opportunity to work with two brilliant scientists and fantastic mentors Matt Groh Dashun Wang 🌟🌟 Come work with us NICO Kellogg School ! Feel free to reach out!

💡 New paper at #CHI2025 led by the amazing Negar Kamali 💡 Large scale experiment with 750k obs addressing 1 How photorealistic are today's AI-generated images? 2 What features of images influence people's ability to distinguish real/fake? 3 How should we categorize artifacts?

How photorealistic are today's AI-generated images? 🤔 Go say hi to Negar Kamali at #CHI2025 and find out more!

What is Claude's EQ? Awesome look into affective convos w/ LLMs Highlights: - 3% of all convos are affective - Claude pushes back 10% of time - People on avg express more positivity over course of convo Related q: How well do LLMs recognize effective empathic support? See 👇

🚨New pre-print!🚨 “Understanding Trust in AI as an Information Source: Cross-Country Evidence”, joint w Marta Serra! Coupling experimental data from 2900 participants & 11 countries with WVS data, we provide novel evidence of individuals' trust in LLMs as info sources.

Time for IC2S2 in Norrköping!! Super excited to share this year’s projects in the lab revealing how (M)LLMs can offer insights into human behavior & cognition More at …boration-lab.kellogg.northwestern.edu/ic2s2 If you're here too, say hi! #IC2S2

🎉 Wednesdays@NICO seminar lineup just dropped!!! We’re bringing together rockstar interdisciplinary speakers on complex systems and data science spanning neuroscience, policy, imagination, AI, design, complexity, and evolution. Join us every Wednesday at noon this Fall

Excited to share our work at CODE@MIT this weekend! Looking forward to new ideas and fun discussions with everyone there ✨
