Undergraduate Student at Peking University · Incoming Ph.D. Student at PKU SEC Lab
Hi! I am Shengxuan Qiu (邱圣轩), an undergraduate student in Microelectronics Science and Engineering at the School of Electronics Engineering and Computer Science, Peking University. I am currently conducting research at PKU SEC Lab under the supervision of Prof. Meng Li, and I will continue there as a Ph.D. student starting in Fall 2027.
My research focuses on efficient AI systems across the model–system–hardware stack. I am broadly interested in making emerging AI workloads more efficient through better algorithms, serving systems, runtime mechanisms, and hardware–software co-design.
🔬 Research
- AI Infrastructure & LLM Serving: distributed inference, scheduling, KV-cache management, speculative execution, runtime systems, and serving-system optimization.
- Reasoning & Agentic Systems: test-time scaling, multi-path reasoning, Tree-of-Thought, agentic workloads, and multi-agent systems.
- Hardware–Software Co-design: MoE acceleration, GPU/NPU systems, 3D near-memory processing, GPU-PIM architectures, and memory-centric AI acceleration.
