Undergraduate research training (“SEMINAR”)
本科科研训练（“专题研究课”）
Research training is an important part of the training program for physics undergraduates at Tsinghua. A training course, called “SEMINAR,” is compulsory for 3rd-year undergraduates majored in physics, in which students can choose mentors according to their interests. The course typically runs for 2 to 3 semesters, giving students chances to experience down-to-earth research and to identify directions for their future studies.
Below is the list of undergraduate students who have officially registered for the SEMINAR courses and undergone research training in our group.
