I am Chuyuan 李楚源. Usually, I go by Lisa.

I have recently joined the University of British Columbia as a postdoc fellow, working with Prof. Giuseppe Carenini. I obtained my Ph.D. in 2023 at LORIA (Université de Lorraine) under the supervision of Prof. Maxime Amblard and Dr. Chloé Braud. I earned my Master’s in Computational Linguistique from Université Paris Cité (Paris Diderot). Before that, I obtained my bachelor’s degree in China, majoring in French Language & Literature, and my Master’s in Strategy & Management of International Business in Paris.

My research interests lie in computational linguistics and Natural Language Processing, including discourse processing, dialogue analysis, and language specificity detection (for instance consistency checking, bias, and language in people with cognitive impairments such as Schizophrenia and Dementia). I am currently exploring how Large Language Models perform at predicting structured knowledge and how to use LLMs properly in practical scenarios such as the mental health domain. I am happy to collaborate with students who are interested in these topics. Please send me an email. 

During my PhD, I conducted research on predicting Schizophrenia patients from a French dataset with specific linguistic features and classical classification algorithms, with some interesting results! (TALN 2020, Journée TLH et Santé). I also worked on depression detection in dialogues leveraging different levels of information within a multi-task learning framework (SIGDial 2022). On discourse processing, I built a semi-supervised pipeline that extracts structural information in Transformers and utilizes only a handful of annotated data (EACL 2023, GdR-Lift 2023, CODI2024, Ph.D. thesis).

I speak French, English, and Chinese. Nature lover, passionate about outdoor activities and traveling.



[2024.02] I will be attending ML for cognitive and mental health workshop (ML4CMH) @AAAI, in Vancouver

[2024.02] I passed the French lecturer qualification, CNU, Section 27 (Informatics)!

[2023.11] I will be joining UBC as a post-doctoral fellow.
