Heading to #EMNLP2026! Excited to share two papers on LLM user simulation: 🧠 KnowSim: Simulating how users learn through AI interactions, validated against real human–AI interaction data across different knowledge levels. 🎭 User Role Vector: Investigating assistant bias in LLM user simulators through internal representations and activation steering. I’m also on the job market! I’d love to connect with folks interested in user simulation, interactive AI evaluation, and oversight for agentic systems. Feel free to DM me!
AI assistants can provide correct, comprehensive information and still be poorly calibrated to the user: too difficult for novices, redundant for experts. KnowSim is a user simulator that tracks what a user knows and updates that knowledge as the conversation unfolds, so we can evaluate information calibration over multi-turn interactions. Across 9 LLMs, model rankings changed with the user’s knowledge level. 📄 arxiv.org/abs/2608.17150

Announcing our new work: Toward Honest Language Models for Deductive Reasoning 🎉 1. We study honesty in settings where a model must derive a conclusion only when it logically follows and abstain when the query is unanswerable. 2. To support this, we curate two multi step deductive reasoning datasets built from graph structures, one for linear algebra and one for logical inference. 3. We find that prompting and existing training methods, including GRPO with or without supervised fine tuning, struggle to reason honestly on these tasks. 4. We introduce ANCHOR ⚓️, a reinforcement learning method that injects ground truth trajectories into rollouts to stabilize learning and prevent early collapse. 📄 Check out the paper: arxiv.org/abs/2511.09222

🚨 New on arXiv! 🚨 "Not There Yet: Evaluating Vision Language Models in Simulating the Visual Perception of People with Low Vision" Can VLMs really simulate what people with low vision perceive? Our findings: Not quite yet. 📄 arxiv.org/abs/2508.10972v1

Meetings often drift off-track. Can AI help us reflect in the moment and realign? Our #CHI2025 paper explores how AI-assisted interventions influence goal reflection during workplace meetings. w/@lev_tank @rishivanukuru @PayodPanda @seanrintel @ava___scott

A week before heading to Japan for #chi2025! I will be presenting a work focusing on immersive story viewpoint and navigation design (arxiv.org/abs/2502.04542). Happy to chat about any experiences on storytelling or VR/AR design!
