I am a PhD student in Quantitative Marketing at Stanford GSB. My research explores how advertising, recommender systems, and AI-mediated environments shape human preferences and decision-making, with the goal of designing systems that enhance individual well-being and social welfare. Another focus of my research is developing human-AI collaboration frameworks that enable AI systems to efficiently learn from expert knowledge while providing informative feedback to human experts. I also work on AI evaluation, LLM post-training, and reinforcement learning methods.
