Prof. Guoping Zhan, born in 1965, is a leading expert in plant quarantine treatment technologies. After graduating from China Agricultural University in 1988, he joined the Chinese Academy of Inspection and Quarantine, focusing on nematode identification, risk analysis, and phytosanitary treatments—especially irradiation. He has participated in major national and international projects, including China's 12th and 14th Five-Year Plans, IAEA and UNIDO-funded programs, and bilateral collaborations with the US and Russia. He has contributed to over ten national and industry standards (three as lead author) and published 80+ papers, 25 in SCI-indexed journals. He initiated the IAEA Coordinated Research Project on irradiation of mealybugs in 2022 and has been a member of the IPPC Technical Panel on Phytosanitary Treatments since the same year. His work supports the development of eight IPPC international standards, four of which have been adopted. Prof. Zhan also reviews for journals such as Insects, Agronomy, Postharvest Biology and Technology, and Radiation Physics and Chemistry. His contributions have earned him multiple provincial and ministerial awards, including one first prize.
