I am currently seeking Ph.D. positions, 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 third-year undergraduate at The Chinese University of Hong Kong, Shenzhen, under the guidance of Prof. Pinjia He. I am currently interning at Trustworthy Engineering of Software Technologies (TEST) Lab, advised by Prof. Manuel Rigger.

My focus lies in AI Robustness (e.g., developing automated tools for testing and improving AI software), testing traditional systems (e.g., databases and compilers), and graph algorithms. 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 50 bugs in these systems.

I am highly involved with Competitive Programming, and in the 46th ICPC World Final List (Egypt 2023). Prior to this, I earned a first runner-up and a second runner-up at ICPC Regionals, representing The Chinese University of Hong Kong, Shenzhen.
