Dark matter search and studies of neutrino properties have been the most important scientific topics on new physics beyond the standard model of particle physics. This talk will give an introduction to CDEX collaboration including its motivation, detector R&D, physical results at CJPL Phase-I. Based on the larger underground space at CJPL Phase-II, CDEX are pushing forward the next generation experiment based on germanium detector array to directly detect light dark matter and search the possible rare processes of neutrinoless double beta decay of Ge-76 isotope. The recent status and prospectsof CDEX will also be introduced in this talk.

Dr. Qian Yue, Professor at Tsinghua University, Project leader of National Key Research and Development Project (No. 2017YFA0402200) and National Natural Science Funds for Distinguished Young Scholar (No.11725522), Spokesperson of CDEX collaboration, Director of Physics Division of China Jinping Underground Laboratory. Main research interests include dark matter direct detection, neutrinoless double beta decay experiment, reactor neutrino and solar neutrino experimental detection, advanced semiconductor detector R&D and so on.
