Welcome NeuroAI Lab @ Kwangwoon Univ. in Republic of Korea. We are conducting research on human-centered AI technology. Our lab wants to make the world better by studying AI technology similar to humans. Our lab provides the best research environment in Korea. We passed the first round 2020 of the Korean artificial intelligence Grand Challenge and won third place on the voice recognition track in the second round 2021. We are always looking for passionate students. If you are interested in our lab, please feel free to contact us. This is the professor's mail and the lab manager's mail.
