About

                                    My expertise is experimental condensed matter. I am working with HiPSEC as a Co-PI on studying material properties under extreme conditions (high pressures and variable temperatures). My research is supported by National Nuclear Security Administration (NNSA) through Stockpile Stewardship Academic Alliance (SSAA). Few of the focus areas include (but not limited to)  investigation of high temperature superconductivity, thermoelectric materials, Phase change memory alloys, heavy fermion behavior in strongly correlated electron systems, valence and spin fluctuations, phase transitions of potential metal hydrides, CMR compounds and nanomaterials. We use variety of techniques such as synchrotron based high resolution powder x-ray diffraction, x-ray absorption (XAS),  Inelastic x-ray scattering (IXS) and x-ray Raman scattering (XRS)  techniques at ambient and high P-T conditions to study the crystal structure, bonding, spin, magnetic, phonon DOS and valence changes. We study the transport and optical (Raman) properties using high pressure diamond anvil and piston-cylinder type cells using in-house facilities.​ Most of our synchrotron experiments are performed at Advanced Photon Source (APS) routinely (HiPSEC is a member user of sector 16-HPCAT). We also use Stanford Synchrotron Radiation Laboratory (SSRL), Advanced Light Source (ALS), National Synchrotron Light Source (NSLS) and Los Alamos Neutron Science Center (LANSCE) for conducting high pressure experiments.
