Hi! Welcome to my home page. πŸ‘‹

I am a postdoctoral researcher at Purdue University hosted by Prof. David J. Love.

Before, I received the B.Sc and Ph.D. degress from the Ulsan National Institute of Science and Technology (UNIST) in 2017 and 2021, respectively. I was fortunate to be advised by Prof. Hyun Jong Yang. From 2021 to 2024, I was a postdoctoral researcher at POSTECH from 2021 to 2024. From 2024 to 2025, I was a postdoctoral researcher at AiSLab in the department of electrical and computer engineering, Seoul National University (SNU). I am interested in publishing flagship journals and conferences in Communication/AI field, such as TWC, TCOM, TMC, INFOCOM, TON, TVT, NeurIPS, ICML, and AISTATS. . For more about me, please check my CV and google scholar.

I am also open to collaborating to explore AI-and-Networking research topics, such as federated learning, over-the-air computing, radio resource management, AI-based signal processing, semantic communication, and AI-RAN.

    IEEE Transactions on Vehicular Technology TVT, 2024-02-20

    We propose a deep-reinforcement-learning (DRL)-based joint UA and RA scheme to maximize the minimum rate, i.e., max-min fairness (MMF), with highly limited information exchange among the BSs. The proposed DRL algorithm optimizes UA at each BS in a distributed manner to maximize an MMF objective function with only local CSI and without any iterative process.

    IEEE Transactions on Vehicular Technology TVT, 2019-11-10

    Motivated by the fact that the condition for obtaining the near-global solution with the dual problem approach is rarely satisfied for increasing number of users, we derive explicit first order optimality conditions to obtain a 2-distance ring solution of the primal UA and RA problem, and propose a sequential optimization method. In addition, we propose a PC algorithm based on the first order KKT optimality conditions, in which transmission power of each RB is iteratively updated.
