Sun Jichao is an Associate Professor at the School of Water Resources and Environment, China University of Geosciences (Beijing). He earned his Ph.D. in Geotechnical Engineering from China University of Mining and Technology (Beijing), completed postdoctoral research in Hydraulic Engineering at Tsinghua University, and served as a Chinese government-sponsored visiting scholar at the University of Wisconsin, USA. 

His research interests span diverse domains of water resources and geological engineering, encompassing hydraulic engineering and water disaster prevention, groundwater seepage mechanics, mechanisms and simulations of water-sediment interaction, modern hydroinformatics and model development & application, as well as geological hazard mitigation technologies. 

In terms of academic service: Dr. Sun currently holds the position of Editor-in-Chief for one international journal, serves on the editorial boards of over ten international journals, and acts as a peer reviewer for more than forty international journals. Additionally, he assumes key roles in numerous international conferences, including International Committee Member, Publication Chair, and Session Chair. 

Dr. Sun’s core academic contributions are:

(1) He pioneered and established the research field of subsurface sedimentology, proposed a comprehensive research framework, and systematically formulated the field’s core philosophy, fundamental tenets, practical mechanical models, and computational programs—laying a solid theoretical and methodological foundation for its advancement.

(2) He achieved substantial breakthroughs in particle flow simulation, with novel insights into composite particle size distribution and gradation. This accomplishment enabled a genuine, substantive alignment between theoretical computations and real-world engineering scenarios, significantly enhancing the accuracy and practical applicability of related calculations.

(3) He developed a particle extrusion force model for fractures, pioneering a new research direction focused on groundwater-driven pore sedimentation. Through systematic investigations, he has generated a wealth of innovative insights, offering fresh perspectives and methodologies for academic research and engineering practice across relevant disciplines.
