Undergraduates | 本科生

Our group provides opportunities for bachelor-thesis projects (for final-year undergraduates) and research training projects (typically for 2nd- to 4th-year undergraduates). Students interested in high energy theories are welcome to contact me.

Bachelor Theses

Below is a list of bachelor theses under my supervision.


Zhuojun Dai: Computing Non-Gaussianities in slow-roll inflation with Schwinger-Keldysh formalism (Tsinghua University)

Zi Shyun Ng: ADM decomposition and its applications (Tsinghua University)

Jiayu Wu: Orbital Modulation of extremal mass ratio inspirals by axion clouds (Beijing Normal University)

Yisong Zhang: A Study of Quantum Hierarchical Three-body Systems (Peking University)


Hongyu Zhang: Scalar QED with finite temperature and in inflationary spacetime (Tsinghua University)

Undergraduate research training (“SEMINAR”)

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, 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.
