We measure the crystal structures and physical properties of materials at extreme high pressure and high temperature, and use these experimental results to model the structure and dynamics in the Earth and planetary interiors. We compress materials using the diamond-anvil cell pressure devices which are available at the MIT high-pressure lab.

In order to measure crystal structure changes at high pressure, we use both micro-Raman spectroscopy and synchrotron X-ray diffraction techniques. Two micro-Raman spectroscopy systems are available at the high-pressure lab at EAPS. X-ray diffraction measurements will be performed at synchrotron facilities, Advanced Photon Source or National Synchrotron Light Source, during summer (two 4-day trip).

We are seeking a UROP student who is interested in performing spectroscopy and diffractometry measurements at high pressure using these state-of-the-art techniques and analyzing the data obtained from these experiments.

Our recent UROPs report their results in peer reviewed scientific journals and at scientific meetings.
