Welcome to Tianao Zhang’s (张天骜) personal website!

I am currently a fourth-year undergraduate student at Shanghai Jiao Tong University (SJTU), majoring in Engineering Mechanics.

I am fortunate to be advised by Prof. Linghe Kong from the School of Computer Science, Shanghai Jiao Tong University (SJTU). I also collaborate with Prof. Yulun Zhang.

My research focuses on model compression and acceleration for Large Language Models (LLMs), with an emphasis on techniques such as binarization and post-training quantization. I am dedicated to building powerful yet resource-efficient AI systems that push the boundaries of computational efficiency. ⚡

I am always open to collaborations and academic discussions! Feel free to reach out via email at ztaztazta2785@gmail.com or via WeChat (ID:ZTAZTAZTAZTAZTA).
