About
Hi👋, I'm Qianli Wang and work as a NLP researcher dedicated to advancing the interpretability and explainability of LLMs at Quality and Usability Lab, Technische Universität Berlin under the supervision of Prof. Dr.-Ing. Sebastian Möller, co-supervised by Dr.-Ing. Nils Feldhus.
News
2026-01-21: Our survey about actionable mechanistic interpretability is now available on arXiv!
2026-01-06: Two first-authored and three co-authored papers in submission about (1) how quantization affects self-explanations❓collaborated with Pepa Atanasova; (2) feedback-driven iterative counterfactual refinement; (3) NLG evaluation trend survey led by Jing Yang; (4) claim-level grounding traceable generation led by Bohao Chu; (5) mechanistic interpretability application survey led by Hengyuan Zhang.
2025-09-27: 📝 One paper about multilingual counterfactual evaluation in collaboration with LMU and Uni Marburg in submission.
2025-09-01: 🌱 Start my research stay in the CopeNLU group led by Prof. Dr. Isabelle Augenstein in Denmark🧜. Thanks for hosting me and providing a nice starting point for our collaborations!
2025-08-21: 💥Delighted to share that (1) Multilingual Datasets for Custom Input Extraction and Explanation Requests Parsing in Conversational XAI Systems accepted at EMNLP 2025 Findings; (2) Truth or Twist? Optimal Model Selection for Reliable Label Flipping Evaluation in LLM-based Counterfactuals accepted at INLG 2025. See you in Hanoi, Vietnam 🇻🇳 and Suzhou, China 🇨🇳! ✈️
