😄 About Me

Hello, I’m Christian Yang (杨智桓 / Yang Chi Wun in Cantonese). I graduated with a Bachelor of Engineering in Artificial Intelligence from Sun Yat-sen University in Fall 2025. Currently, I’m taking a gap year working as an AI Engineer at Sengine AI, a promising startup, where I focus on Retrieval-Augmented Generation (RAG) and Multi-Agent Systems.

During my undergraduate studies, I had the fortune of receiving academic guidance from Dr. Zhao Song and Dr. Yingyu Liang. My research interests include Large Language Models (efficient training & inference, reasoning, and science of LLMs), AI Security, and Deep Learning Theory. I welcome discussions, critical feedback, or novel ideas related to my work—please don’t hesitate to reach out via email at christiannyang37 [at] gmail [dot] com.

I am now actively preparing for the next phase of my career and am seeking PhD student positions or on-site research internships commencing in Fall 2026. I am open to discussing potential opportunities and collaborations.
