On Christensen's Linkedin page, relevant media found that Christensen introduced himself as a doctoral student in the physics department of UIUC. In the column of work experience, Christensen said that he has been working as a teaching assistant since 20 13, mainly responsible for teaching 20 students, answering their questions in physics, marking papers, exams and so on.
Regarding the identity of the suspect as a teaching assistant, YINGYING ZHANG's former colleagues said that the suspect was a doctoral student in our school. In the WeChat group looking for volunteers in YINGYING ZHANG, it was also pointed out that the suspect was his roommate and teaching assistant in his freshman physics class 10 1.

Relevant media also interviewed Li Ming (a pseudonym), who had an intersection with him and was also a physics student at the University of Illinois at Urbana-Champaign (UIUC).

Li Ming said it was about 20 13 or 20 14 years. Before they joined the research group, doctoral freshmen usually had to be teaching assistants, that is, they changed their homework, took discussion classes and took experimental students. "I talked to him several times and never had dinner together." But at that time, Christensen left Li Ming with the impression that he was more cheerful and "liked playing fighting games very much".
