Qiuyang Mang

I am currently seeking Ph.D. positions for 2025 Fall, aiming to combing interesting algorithms with practical applications. If you are interested in me, please feel free to contact me!

I am Qiuyang Mang (忙秋阳 in Chinese), a final-year undergraduate at The Chinese University of Hong Kong, Shenzhen (CUHK-Shenzhen), under the guidance of Prof. Pinjia He. I am currently interning at Trustworthy Engineering of Software Technologies (TEST) Lab in the National University of Singapore, advised by Prof. Manuel Rigger. My focus broadly lies in AI Robustness [ESEC/FSE23] (e.g., developing automated tools for testing and improving AI software ), testing traditional systems [ICSE24] (e.g., databases and compilers), and graph algorithms [KDD24] (e.g., GNN and graph mining). More recently, I have been focusing on testing graph database management systems (e.g., Neo4j) and graph algorithm libraries (e.g., NetworkX). Our work has successfully detected more than 80 bugs in these systems.

In addition to my research, I am actively involved in Competitive Programming. I participated in the 46th ICPC World Finals in Luxor, Egypt (2024). Prior to this, I earned first runner-up and second runner-up positions at ICPC Regionals, representing CUHK-Shenzhen. I have also served as a jury member and problem setter for several official ICPC contests (currently as a member of SUA). Additionally, I participate in Olympiad Informatics education, including NOI and USACO. As part of my part-time job, I am a senior coach at Xinyoudui (信友队 in Chinese) and X-camp for course designing and teacher management. If you are interested in collaborating on Competitive Programming, please feel free to contact me.
