On November 30, 2020, the “Innovation Base of Earthquake Engineering Comprehensive Simulation” 38th “Cloud Report” was successfully held. This lecture invited Prof. Jian-Qiao Sun from University of California at Merced, to give a special report entitled “Studies of Nonlinear Stochastic Dynamic Systems with Concepts and Methods from Data Science”.
This report was hosted by Prof. Haitao Zhu from the School of Civil Engineering, Tianjin University. During the lecture, Prof. Jian-Qiao Sun provided latest research findings and engineering applications of machine learning. Then Prof. Jian-Qiao Sun mainly focused on recent applications of the concepts of data science to global analysis of nonlinear dynamic systems and to the solution of Fokker-Planck-Kolmogorov (FPK) equation of nonlinear stochastic dynamic systems.
After the report, the participating teachers and students had a heated discussion on related issues and took a group photo online (Fig. 1). According to statistics, more than 100 teachers, researchers and students attended this report. The effect of the lecture was remarkable. The audience responded enthusiastically to this lecture.

Introduction to Prof. Jian-Qiao Sun:
Katalin Bagi is currently a full professor at the Department of Structural Mechanics of Budapest University of Technology and Economics. She has an engineering and a mathematics diploma, and received different university and academic degrees (Ph.D. Dr Habil; CSc, DSc) in computational mechanics. She has three related fields of expertise: (1) granular micromechanics; (2) mechanics of masonry arches and vaults; (3) discrete element modelling. As a world-renowned researcher in these fields, she has organized several conferences, workshops and seminars, and edited different books and journal special issues. She has about 1400 independent citations, with a Hirsch index of 20.
Jian-Qiao Sun earned a BS degree in Solid Mechanics from Huazhong University of Science and Technology in Wuhan, China in 1982, a MS and a PhD in Mechanical Engineering from University of California at Berkeley in 1984 and 1988. In 1994, Dr. Sun joined the faculty in the department of Mechanical Engineering at the University of Delaware as an Assistant Professor, was promoted to Associate Professor in 1998 and to Professor in 2003. He joined University of California at Merced in 2007, and is currently a professor and chair of the Department of Mechanical Engineering in School of Engineering. Besides many other editorial experiences, he is the Editor-in-Chief of International Journal of Dynamics and Control published by Springer. His research interests include stochastic non-linear dynamics and control, cell mapping methods, multi-objective optimization, high-density piezoelectric energy harvesting from highway traffic and data-driven energy management of office building HVAC systems.
