Qu Zixuan, class of 2025 in Computer Engineering of ZJUI. As a member of the 6th Presidium of the Student Union at the International Campus, Zhejiang University and one of the founding members of the " XinHai Learning Hub". Qu Zixuan has actively participated in international events, such as the Student Innovation Forum held by Sichuan University-Pittsburgh Institute and the Dialogue Event with German Vice Chancellor Robert Habeck.

 

Academically, Qu has received the Zhejiang University Second-Class Scholarship, the Nandu Innovation Scholarship, and has been honored with titles such as "Outstanding Student" of Zhejiang University. His exceptional contributions as a peer academic tutor earned him the title of "Star Peer Tutor," in addition to being recognized as an "Academic Excellence Model Student" and "Social Engagement Model Student."

 

In terms of competitions, Qu was awarded the Meritorious Winner in the 2024 Mathematical Contest in Modeling (MCM) . Ultimately, he obtained exemption from examinations for doctoral program, ranking first in the interview process, and will continue his academic journey at the College of Electrical Engineering, Zhejiang University.

 

Qu Zixuan has a deep passion for photography. After arriving at the international campus, he was captivated by its stunning scenery and rich cultural diversity. He actively joined ZJUI’s branding and publicity team, using his lens to capture campus life while honing skills in photography, writing, and teamwork. These experiences broadened his perspective and deepened his sense of social responsibility. During a student dialogue event with the German Vice Chancellor, he expanded his global outlook and gained a deeper understanding of the value of international communication. To foster a positive academic atmosphere, he and his peers launched the “XinHai Learning Hub,” a diverse, student-led platform for academic support and skill-sharing, which has been well-received by both students and faculty. As a student representative, he also participated in the Student Innovation Forum, promoting intercollegiate exchange, and played an active role in admissions outreach efforts.

 

While many of his ZJUI peers chose to pursue studies abroad, he opted to stay in China due to his deep interest in Computer Engineering. The ZJUI faculty and cutting-edge research environment at ZJUI further solidified his decision. Under the guidance of Assistant Professor Hao Yang, he participated in a project on human activity recognition using wireless signals, successfully developing a fall detection system based on CSI signals—his first experience transforming theoretical models into engineering practice. Under the guidance of Assistant Professor Cheng Yushi, he systematically evaluated the defense capabilities of mainstream models, Including the GPT, Llama, and Qwen series—against attacks like AutoDAN, GCG, and Cipher. The study comprehensively analyzed semantic features related to LLMs and proposed a lightweight system prompt protection method based on natural language semantics, raising the defense success rate of major models to over 95%. The findings are currently under submission for publication. And he also actively participated in the MCM/ICM Mathematical Contest in Modeling, winning Meritorious Winner and Honorable Mention awards, and gaining hands-on experience in research methodology and interdisciplinary collaboration. In the 4th Zhejiang University Concrete Dragon Boat Competition, he integrated traditional dragon boat culture with modern motor control technology, further honing his interdisciplinary thinking and practical skills. 

"I am a slow walker, but I never walk backward." As he shared in 2025 Commencement, he hopes to maintain the courage and direction to keep moving forward in the future, approaching the radiance of truth through relentless and sustained effort.
