Profile

I am a Ph.D. candidate in Computer Science at Nara Institute of Science and Technology (NAIST), Japan. My research interests include distributed systems, software-defined networking (SDN), and reinforcement learning, aiming to build high-performance, adaptive, and reliable network systems.

In particular, I focus on dynamic controller placement, distributed storage optimization, and network latency modeling in large-scale SDN environments. I combine reinforcement learning with real-world network data to design self-adaptive deployment strategies that enhance efficiency, load balancing, and responsiveness in distributed networks.

I am committed to advancing the core technologies of next-generation intelligent networks by bridging theoretical advances in machine learning and practical challenges in distributed system design.
