Our group explores high pressure solid state chemistry using large volume presses and diamond anvil cells with in situ studies carried out using optical spectroscopy and synchrotron X-ray scattering. Synthesis-properties studies of new classes of functional materials are also being carried out at ambient conditions using chemical precursor techniques. New research areas in high pressure biophysics and microbiology are being developed. In situ optical spectroscopy (Raman, FTIR) is applied to problems in Earth and planetary science, catalysis and biomedicine. Structural studies of glasses and amorphous materials including polyamorphism and liquid-liquid phase transitions are on-going.
