Hi, I'm a graduate student at the Ubiquitous AI Lab, advised by Prof. Taesik Gong. My research interests span adaptive AI, efficient AI, and on-device AI. I study how AI systems can adapt across tasks, environments, and users, how models and agents can use less computation and memory, and how to bring these systems to resource-constrained edge devices. My work also explores personalization and reliability in GUI agents. Ultimately, I hope to help democratize AI by making it efficient enough to fit seamlessly into everyday life.
