I have a broad research interest in building trustworthy language models, with current focus on improving their robustness and alignment. Previously, I conducted research on language models’ social good, especially in empathetic dialogue systems. I have also built a series of popular NLP datasets, including ChID, KDConv, ESConv, and CDConv.
