Natural Language Processing

Zichen Song is an incoming Combined Master-PhD student in Computer Science and Engineering at Sungkyunkwan University (SKKU), South Korea (Fall 2025). His research focuses on security and privacy for large language models - particularly membership inference and data extraction attacks - as well as optimization of (multi)modal LLMs, deep spiking neural networks, and medical AI.

His broader interests include trustworthy AI, federated learning, and efficient training/inference for foundation models. He has experience with Python, C/C++, PyTorch, TensorFlow, and Linux, and enjoys building reproducible research codebases and clean experimental pipelines.
