Biography: Member of the Academy of Science of South Africa (elected in 2010) and Chair Professor at the Institute of Nano Energy and Nanosystems, Chinese Academy of Sciences.

He obtained his PhD degree from Lanzhou University in 1989, under the supervision of Professor Ye Kaiyuan. He has previously engaged in research work at Tsinghua University, Delft University of Technology (the Netherlands), Ruhr University Bochum (Germany, as an Alexander von Humboldt Fellow), University of Cape Town (South Africa), Jinan University (serving as the founding Dean of the International College), and Xi'an University of Architecture and Technology (serving as the Dean of the Institute of Mechanics and Technology, IMT). Before returning to China, he held the position of Tenured Professor in the Department of Mechanical Engineering at Cape Peninsula University of Technology (South Africa).

He has authored and edited works including *Dimensional Analysis and Lie Groups* and *Toroidal Shells*, and translated *The Biography of Ludwig Prandtl*. His representative achievements are as follows:
1. Successfully solved the unsteady laminar boundary layer problem proposed by L. Prandtl in 1904 by introducing similarity transformations, and obtained for the first time an exact solution expressed by Kummer functions for planar flow;
2. Proposed two generalized Kepler's laws of periodicity for three-body and multi-body systems in Newtonian gravitational fields (dubbed the "Sun Bohua Conjecture" by Belgian physicist Claude Semay);
3. Obtained for the first time the exact solution for axisymmetric bending of toroidal shells expressed by Heun functions;
4. Addressed Qian Weichang's doubts about Hu Haichang's generalized variational principle using thermodynamic theory;
5. Derived for the first time the universal scaling law that the propagation speed of the domino effect is proportional to the 1/2 power of the domino spacing using directional dimensional analysis;
6. Obtained for the first time the universal scaling laws via dimensional analysis, which state that the aerodynamic drag of dandelion seeds is proportional to the -2/3 power of the Reynolds number and the terminal velocity is proportional to the 3/4 power of the weight (mg);
7. Proposed a bionic lattice structure inspired by glass sponges, with mechanical properties surpassing those of natural materials.
Two of his achievements have been reported in *National Science Review*, and have also been featured in special articles by *Science China (Series A: Mathematics, Physics, Astronomy)* and *Chinese Physics B* respectively.

In 2010, he was selected as an Outstanding Alumnus of the Postdoctoral Program at Tsinghua University and one of the "Top 10 News Figures of the Global Chinese Community" in the same year.

Currently, he also holds concurrent positions including Extraordinary Professor at Stellenbosch University (South Africa), Member of the Editorial Board of *Acta Mechanica Sinica*, Chief Editor of the book series *Frontiers of Mechanical Fundamentals and Engineering Technology* published by Higher Education Press, Advisor to the Editorial Board of the journal *Physics of Fluids*, and Director of the Academic Committee of the Jiangsu Applied Mechanics Center (China University of Mining and Technology).
