Sun is a candidate for the China Academy of Engineering of Shanghai Jiaotong University, and was nominated by the Institute of Nonferrous Metallurgy of Shanghai Jiaotong University. This is the first condition for him to become an academician.

To become an academician, candidates need to go through a rigorous screening and evaluation process, including academic achievements, reputation and contribution in this field, and whether they meet the qualification requirements of academicians. These evaluation criteria are very strict and specific, which require candidates to make significant contributions in their fields and be recognized by peer experts.

Therefore, although Sun has already qualified as an academician of China Academy of Engineering, whether he can eventually become an academician still needs a rigorous evaluation and screening process, and it depends on whether his academic achievements and contributions meet the qualification requirements of academicians and whether he is recognized by his peers.

I can't predict whether Sun will eventually become an academician, but I can know that he has made remarkable achievements in the academic field and has been recognized by his peers. We look forward to his future development and wish him to realize his dream of becoming an academician.
