The main research directions are: geotechnical engineering testing technology, safety monitoring technology, and security electronic technology.

In 2001, we obtained one utility model patent for "Plastic Thermal Bonding Coil" and one invention patent each for "Plastic Thermal Bonding Coil, Manufacturing Method and Mold Used". The patented technology transfer fee was 300,000 yuan. Mengao Company used this technology to earn US$550,000 in foreign exchange (equivalent to more than 4.6 million yuan) and a net profit of more than 2.7 million yuan in more than a year. It was praised by American technical personnel and was The United States has designated it as an inspection-free product. At the same time, the employment problem of more than 40 laid-off workers in Baotou was solved.

In his 25 years of teaching and scientific research, he has been rated as an advanced individual at the school and college levels many times, published nearly 20 scientific research papers, and became a member of the Inner Mongolia Safety Science and Technology Association in 2006. He has been engaged in on-site scientific research and technical services for many years. He is hard-working and dedicated in research, and has won unanimous praise from company leaders and employees.
