About Zhiheng

Hi, here is Zhiheng. Welcome to my personal website, nice to see you😆~ I’m currently seeking a PhD position on the term of 24Fall. My research interests are specifically focused on structural text planning and generation, causality in natural language processing, and the development of efficient large language models (LLMs). I am deeply passionate about advancing the field of AI by creating innovative systems that merge language structures with logical reasoning to address complex real-world problems efficiently. – for more details, please see my SoP and CV.

Currently I’m a senior undergraduate student major in Computer Science in University of Hong Kong, supervised by Lingpeng Kong. Last summer, I work at the Berkeley NLP, supervised by Kevin Yang and Prof Dan Klein, focusing on fact tracking and contradict detection in a narrative structure, such as story outline. Previously, I’ve worked at the ETH NLPED Lab under the supervision of Zhijing Jin and Dr. Mrinmaya Sachan, and as a research intern at Megvii.

Research Highlight

  • Fact tracking and contradict detection in story outline
  • Probing the Understanding of Large Language Model in Causality
  • Explore new Training Paradigm for a Causal Graph based on Conditional Independent Test
  • Construct and Pre-process Datasets on NLP for Social Good
