Hyerin Kim

I’m currently pursuing my Ph.D. in Computer Science at the Technical University of Munich under the supervision of Prof. Jörg Ott.

I received my M.S. in Computer Science and Engineering from Seoul National University, South Korea, where I was advised by Prof. Wha Sook Jeon. My master’s research focused first on resource allocation for device-to-device C-V2X sidelink communication, and later on designing an optimization framework for MAC-layer resource scheduling at the QoS-flow level.

I obtained my B.S. in Computer Science and Engineering from Sogang University, South Korea. As an undergraduate researcher under Prof. Jungmin So, I conducted research on improving spatial reuse in dense Wi-Fi environments, and also led several software development projects.

Research Interests

Flow-level QoS-aware Resource Allocation at MAC layer
- Scheduling algorithms to provision QoS for each flow in B5G
- Applying both optimization-based formulations and reinforcement learning (RL) approaches
Distributed Resource Allocation in Wireless Networks
- Addressing exposed and hidden terminal problems
- Improving overall performance by estimating the states of neighboring devices
Cross-layer System-level Orchestration for Multi-flow Resource Allocation
- Establishing slicing policies by aggregating information of flows within each slice
- Leveraging orchestration frameworks such as O-RAN to optimize the interactions between MAC-layer parameters and application-layer requirements (further study)
