INA Research Group

Welcome to Intelligent Network Architecture Lab @ KAIST!


INA research group pursues innovative ideas in/for Internet services and applications, cloud infrastructure, and systems that support artificial intelligence. We identify and anticipate new problems that arise from the evolution of Internet-/Cloud-based services and the development of new hardware, provide novel solutions for challenging problems in the real-world, design and implement the solutions in a way that reaches out for real-world impact. INA is part of the Computer Division of the School of Electrical Engineering.
