Hi👋, I’m Qianli Wang and work as a NLP researcher dedicated to advancing the interpretability and explainability of LLMs at XplainNLP group, Quality and Usability Lab, Technische Universität Berlin under the supervision of Sebastian Möller.

Research interests 👀

Topics of interest are post-hoc explanations (especially counterfactual example, free-text rationale), interactive conversational XAI systems, mechanistic interpretability, reasoning, multilinguality, evaluation, alignment.

News ✨

2025-05-19: 💫 Three first-authored papers in submission about (1) multilingual explanation request parsing and custom input extraction in ConvXAI; (2) counterfactual validity evaluation for counterfactual data augmentation; (3) how does quantization affect model explainability and interpretability.

2025-05-15: The 4th first-authored paper titled FitCF: A Framework for Automatic Feature Importance-guided Counterfactual Example Generation accepted at ACL 2025 Findings, which will be hold in Vienna, Austria! 🍻

2025-05:15 🚥 Thrilled to announce that I will be conducting a research stay in September at the CopeNLU group, led by Isabelle Augenstein, funded by the Danish Data Science Academy (DDSA).
