Prof. Dr. Yintong Guo graduated from the China University of Petroleum (East China) with a bachelor’s degree in 2005 and from the Wuhan Institute of Rock and Soil Mechanics at the Chinese Academy of Sciences in 2010 with a Ph.D. in geotechnical engineering. In July 2010, he served as an assistant researcher at the Wuhan Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, and as an associate researcher in December 2012. He has been a researcher since December 2020. He won the first prize of Hubei Science and Technology Progress in 2010, the first prize of Beijing Science and Technology Progress in 2015, the third prize of Hubei Science and Technology Progress in 2016, the third prize of Beijing Science and Technology Progress in 2018, the second prize of Hubei Science and Technology Progress in 2019, and the first prize of China Petroleum and Chemical Automation Application Association Science and Technology Progress in 2020. His research interests include rock mechanics in petroleum engineering, large-scale physical models of fracture extension and quantitative characterization technology of mesh fractures, multi-fracture fracturing theory, post-fracturing effect evaluation, and high-temperature rock damage mechanics of hot, dry rocks.
