Xiao-Jia Chen

Xiao-Jia Chen works in condensed matter physics. His research is focused on magnetism and superconductivity of materials under high pressure. Currently, he is coordinating the Spallation Neutrons and Pressure (SNAP) project – the exciting new high-pressure neutron science at the Spallation Neutron Source, Oak Ridge National Laboratory.

Xiao-Jia received his Ph.D. from Zhejiang University in China in 1997.
