I am a PhD candidate at the University of Michigan School of Information, advised by Eric Gilbert and Ceren Budak.

Population-Scale AI Interaction

View the full-size figure showing how AI can expand what people consider and how AI-generated ideas and judgments spread through populations.
  1. Build perspective-expanding interventions. I build systems that simulate perspectives and policy futures to expand what people consider.
  2. Measure the collective dynamics of human–AI interaction. I design experiments in which AI-generated ideas and judgments pass between people, making population-level effects measurable.

Research overview and CV

Selected Publications

NeurIPS 2025 (Spotlight πŸ† - top 4% of submissions)

We introduce an evaluation framework that tests whether LLMs learn fundamental human values or merely surface-level preferences. Across 9 models, the average Deep Value Generalization Rate is just 0.30, meaning all models generalize deep values less than chance.

CHI 2025 (Honorable Mention πŸ† - top 5% of submissions)

We introduce Plurals, a system and Python library for pluralistic AI deliberation. Three randomized experiments show simulated focus groups produced output resonant with relevant audiences (chosen over zero-shot generation in 75% of trials). Python Library | Docs

ACM Collective Intelligence 2025 (Honorable Mention πŸ†)

We conducted an experiment (800+ participants, 40+ countries) using a dynamic "many-worlds" design. We find that high AI exposure increased collective diversity but not individual creativity. AI made ideas different, not better.

Mathematical Art

I create generative art using programming, randomness, and geometry. My work explores the intersection of mathematical patterns and aesthetic expression.
