Dr. Ren currently is an assistant professor in SUSTech and a committee member of Professional Committee on Seismoelectromagnetism, Seismological Society of China. He received degrees of B.Sci. and Ph.D. from Peking University in 2003 and 2009, respectively. From 2009 to 2016, he served first as a postdoctoral researcher and then as an associate researcher in University of Science and Technology of China. In October 2016, he joined Southern University of Science and Technology. Two months later, he was identified as high-level personnel of Shenzhen City. From June to October in 2017, he visited Earthquake Research Institute, The University of Tokyo carrying out internationally cooperative study on co-seismic electromagnetic (EM) signals observed during 2016 Kumamoto earthquakes. His research interests include EM phenomena associated with natural earthquakes and the potential applications of seismoelectric effect in detecting or monitoring subsurface fluid. He is the internationally first person who puts forward the existence of seismoelectric evanescent EM waves further perfecting the seismoelectric theory. So far, he has hosted four scientific research projects and published more than 10 journal articles. He has served as a project assessor of National Natural Science Foundation of China as well as a reviewer of scientific journals including JGR, GJI, SE, PAGeoph, and so on.
