🤵🏻 About me

Hi, my name is Shi-Tong Peng and I joined Shantou University as an associate professor in 2020. If you are seeking any form of academic collaboration, please feel free to reach out at shtpeng@stu.edu.cn (email preferred) or 18018985971 (phone).

My research interests include process monitoring, additive manufacturing, uncertainty quantification, energy/quality management, and life cycle assessment. I have published 30+ papers with total

🎓Graduate Research Opportunities

I am actively seeking 2 motivated Master students to join my small research group each year. Candidates with backgrounds in Mechanical Engineering, Computer Science, Mathematics, Electronics, or Automation are encouraged to apply.

  • What I value:
    • Strong self-motivation and commitment to research.
    • Outstanding academic performance (GPA ≥ 3.5 or equivalent).
    • Solid mathematical foundation (e.g., >100/150 in postgraduate entrance math exams).
    • Interest in long-term research (Ph.D. aspirants are particularly welcome!).
  • What I offer:
    • Collaborative mentorship focused on deep algorithm development and industrial applications.
    • An inclusive environment — your potential matters more than your undergraduate institution.
    • Monthly stipend.
    • Active support for doctoral applications.
