My name is Hang Zhao, a six-year Ph.D. candidate at the Computer Science Department, Stony Brook University. I was interning at Meta as a Machine Learning Engineer working on Large Language Models fine-tuning. Here is my Google Scholar profile. My Resume is attached. My advisor is Prof. Xiaojun Bi. I am doing research at the HCI lab. My research experiences are related to Machine Learning, Deep Learning (Transformer, CNN, LSTM), Reinforcement Learning (DQN), AI medical diagnosis, and Large Language Models.
