His main research fields are quantum field theory and string theory, and he has done a series of work with important international influence in loop diagram calculation of quantum field theory, including:

(1) He is the first to verify the duality of color factor and momentum factor at the quantum five-loop level, which is a breakthrough in that this duality only stays in four loops for a long time, and may be an important inspiration for understanding quantum gravity.

(2) He is the first to calculate the nonplanar contribution of the cusp anomalous dimension, and the first to explicitly deny the quadratic Cartesian scale conjecture at the perturbation level, which is of great significance for understanding the infrared divergence of gauge theory.

(3) He is the first to calculate all the rational terms of the six-gluon QCD single-loop amplitude, marking the first time that the complete analytical calculation of the six-gluon amplitude was realized thirteen years after the calculation of the five-gluon amplitude.

His related work has been invited to be reported at many important international conferences in the fields of high-energy physics and amplitude, such as the Strings, the International Annual Conference on Amplitude, and QCD Meets Gravity.
