About Me

I am a first-year Ph.D. student at the School of Electrical Engineering at KAIST, under the guidance of Prof. John Kim.

I love computer architecture and also have a strong interest in security!

My research so far has focused on side-channel attacks and measurement studies on GPUs. Currently, I am doing research about resilient distributed training and problems related to NVSwitch. More recently, I have become interested in speculative decoding and differential privacy with fine-tuning, so I would love to discuss various problems related to these topics :)
