Yangbo Wei (韦杨波) is a second-year Ph.D. student in the School of Electronic Information and Electrical Engineering, Shanghai Jiao Tong University (SJTU), supervised by Prof. Lei He (IEEE Fellow). Prior to my journey in SJTU, I obtained my B.Sc. degree in Physics from Southeast University (SEU) in 2024.

My research interests lie at the intersection of AI Agents, Computer Architecture, and Electronic Design Automation (EDA).

My current research focuses on the following areas:

• AI Agents & Reasoning: Emotional Agent, Multi-Agent System (MAS), and agentic reasoning.
• AI Hardware Acceleration: FPGA-based Overlay Processor Units (OPU) for LLMs, Speculative Decoding architectures.
• LLM System Optimization: Quantization, sparsity, and KV-cache management.
• AI for EDA: LLM Agents for EDA.
