Zhenxian Liu is beamline scientist at the Carnegie synchrotron infrared beamline U2A of the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory. He manages this high pressure facility, which has been fully operational since 1999 and is currently supported by CDAC, COMPRES, and the Carnegie Institution of Washington.

The U2A beamline was the first synchrotron facility dedicated to high-pressure infrared microspectroscopy and micro-Raman spectroscopy and remains unique in the world. The facility is located at an end station of the  VUV-IR ring of the NSLS. Zhenxian actively develops novel experimental techniques (e.g., vacuum far-IR spectroscopy down to 50 cm-1 at high pressure, and assists users in carrying out research projects in geoscience, planetary science, materials science, condensed matter physics, chemistry, and biology. Specifically, he uses synchrotron infrared spectroscopy, Raman scattering, photoluminescence as well as synchrotron x-ray diffraction techniques to explore physical and chemical properties and phase transitions of hydrous minerals, simple molecular systems, and nanoscale materials at high pressures and variable temperatures.

Zhenxian received his Ph.D. from Jilin University, China in 1990.
