Kim primarily works on two important challenges for high-speed, high-volume information processing systems — how to describe information efficiently, and how to transmit it reliably in the presence of noise and interference. He is a co-author of the textbook, Network Information Theory. Kim earned his bachelor’s degree with honors in electrical engineering from Seoul National University, receiving a GE Foundation Scholarship. Kim has served as a distinguished lecturer for the IEEE Information Theory Society, and as Associate Editor for the IEEE Transactions on Information Theory. He is a Fellow of the IEEE.
