šŸ”Ž Research Interest

My research focuses on multi-modal personalization, leveraging video, images, text, and structured signals such as graphs and user histories to model individual preferences. I am particularly interested in aligning generative and retrieval models with user-specific rewards and long-term interaction patterns, thereby bridging the gap between conventional general benchmarks and real-world personalized experiences.
