Primarily engaged in research on the fundamental physical properties and kinetics of natural gas hydrates, as well as the development of hydrate derivative technologies, he currently presides over the National Natural Science Foundation of China (NSFC) projects "Research on the Evolution Law of Geomechanical Parameters during the Extraction Process of Natural Gas Hydrates in the South China Sea" and "Research on the Mechanical Properties of Marine Natural Gas Hydrates and the Mechanical Risk Factors in the Extraction Process". He also leads several projects funded by the Guangdong Provincial Science and Technology Innovation Strategic Special Funds, including "Stratigraphic Deformation Mechanism during the Extraction Process of Natural Gas Hydrates in the South China Sea", and several projects funded by the Guangdong Provincial Special Funds for Promoting Economic Development (for marine economic development purposes). Additionally, he has participated in one project from the National Key Research and Development Program as a technical backbone. As the project leader, he has successfully completed multiple projects, including NSFC projects and key projects of the Guangdong Provincial Science and Technology Plan, and has contributed to the completion of several national projects such as the 973 Program, 863 Program, and NSFC projects.

Core member of the local innovation team under the Special Support Program of Guangdong Province; awarded one second prize and one third prize for scientific and technological progress in Guangdong Province, as well as three other scientific research awards at or above the provincial level.
