Since my initial encounter with machine learning in 2021, my Ph.D. journey has led me to sequentially explore affective computing, causal analysis, probabilistic methods, language models, and mechanistic interpretability. The most fascinating part of it all has been the process of independent exploration.

Postdoctoral Research Fellow at Nanyang Technological University
Hang Chen received his Ph.D. from the Faculty of Electronic and Information Engineering at Xi’an Jiaotong University in March 2026. In June 2026, he joined the College of Computing & Data Science (CCDS) at Nanyang Technological University (NTU) as a Postdoctoral Research Fellow, working with Prof. Wenya Wang. His research is rooted in causal representation and structural analysis in machine learning. Recently, his focus has shifted towards applying the mechanistic interpretability of Large Language Models (LLMs) to guide and control post-training processes, such as Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL).
