Undergraduate @Umich @SJTU @ SLED

Here is Xuejun Zhang. I am a senior double majoring in Electrical and Computer Engineering at Shanghai Jiao Tong University and Data Science at University of Michigan. I am an undergraduate research assistant in SLED Research Lab advised by Professor Joyce Chai.

My research explores the fundamental question of whether artificial intelligence can achieve true understanding, with a focus on multimodal learning and natural language processing (NLP). I am particularly interested in:

  1. Evaluation of Multimodal Understanding: Developing systematic evaluation methodologies to expose limitations in how models process and integrate information across modalities.
  2. Alignment and Model Capabilities: Investigating methods for aligning models toward different forms of understanding while preserving their core capabilities.
  3. Mechanistic Interpretability: Analyzing the internal mechanisms of neural networks to understand how they construct representations and process multimodal information.

I’m actively seeking a PhD position starting in Fall 2025!
