Woojung Song

I'm an integrated M.S.–Ph.D. student in Data Science at Seoul National University, advised by Yohan Jo in the HOLI Lab. I study the behavioral evaluation and alignment of language agents. My research examines whether assessments of values and behavioral tendencies predict responses in realistic interactions, how faithfully language models represent human traits and evolving personas, and how agents respond to challenging users and unreliable tools. Through benchmark design and behavioral interventions, I aim to develop agents whose behavior more closely aligns with human needs and values.
