Research: Interdisciplinary research centred on theoretical and computational physics. Development of simulation methodologies and their application to studies of minerals at high pressures and temperatures, and to design of new materials. Understanding the factors governing the structure and properties of solids, their structural, electronic, and magnetic transitions. My group pursues research on several projects. Among the highlights of our research are:

1) USPEX: Novel Method for Crystal Structure Prediction (EPSL 2006, J.Chem.Phys. 2006, Comp.Phys.Comm. 2006).

2) Joint theoretical/experimental discovery of MgSiO3 post-perovskite, the main mineral of the Earth's D'' layer (Nature 2004). This discovery has been confirmed by a number of independent studies.

3) First theoretical studies of the rheology of MgSiO3 perovskite and post-perovskite (Nature 2005) based on first-principles metadynamics, and a new interpretation of the seismic anisotropy of the Earth's D" layer. Prediction of a polytypic series of structures between perovskite and post-perovskite, possible new mantle minerals, experimentally confirmed by O.Tschauner in 2008.

4) Ab initio phase diagrams of Earth-forming minerals (Nature, PNAS, PRL, Phys.Rev.B, J.Chem.Phys., 2003-2006).

5) Mineral physics interpretation of seismic tomography in terms of temperature distribution in the Earth's mantle (Nature 2001). Thermal model of the Earth's mantle (EMU Lecture Notes 2002).

6) Advanced pressure calibration methods for experiments in diamond anvil cells, and novel P-T pressure scales (DAN 2003, 2006; PRB 2007).

7) Discovery of novel high-pressure phases of the elements - partially ionic phase of boron (Nature, February 2009) and transparent insulating phase of sodium (Nature, March 2009). Prediction and elucidation of pressure-induced structural transitions in silane (PRL 2009), germane (PRL 2008), carbon (PRL 2009), nitrogen (PRL 2009), novel lithium hydrides (PNAS 2009), stannane (PNAS 2010).

8) Development of a method for quantifying and visualizing energy landscapes (J.Chem.Phys. 2009).
