About Me
I am a Ph.D. candidate at Yonsei University, working under the supervision of Prof. Hojung Cha. My research builds system software that enables vision foundation models to run efficiently on heterogeneous mobile SoCs, with a focus on mobile NPUs (or neural engines). My core research interests include:
- On-Device AI
- Systems for ML
- Mobile Systems and Heterogeneous Computing
To address the challenges of accelerating on-device ML on resource-constrained platforms, I take the following approaches:
- Hardware-aware inference optimization for mobile NPUs: Maximizing data locality and hardware utilization of mobile NPUs (e.g., Qualcomm Hexagon NPUs) through hardware-efficient quantization and graph-level optimizations
- System-level inference optimization for mobile SoCs: Distributing inference workloads across heterogeneous accelerators (NPU, GPU) under mobile platform dynamics (e.g., shared-resource contention, power constraints) to meet real-time performance and energy efficiency goals.
