We are experimental condensed matter physics group in the Department of Physics at the University of California, San Diego. Our group studies nanoscale dynamics and structure of materials - splitting our interest between "soft matter" and electronic/magnetic materials.

We are particularly interested in developing novel coherent x-ray scattering techniques to probe dynamics in variety of condensed matter systems, ranging from electronic and magnetic phases (charge-, spin-, orbital ordered systems, magnetic thin films and nanostructures, metal-insulator transitions and new high-temperature superconductors) to soft matter including fluids, colloids, nanoparticles, polymers and glasses as well as behavior of materials in nanoscale confinement.

Our in-house experimental capabilities include Dynamic Light Scattering and Light Microscopy laboratories, Atomic Force (AFM) and Electrostatic Force (EFM) Miroscopes, Microfocus X-ray Rotating Anode system, He flow cryostat for microscopy, Sputtering Deposition System (co-owned with Prof. Eric Fullerton). We also use a number of National Laboratory User Facilities, including Advanced Photon Source and Center for Nanoscale Materials at Argonne National Lab, Advanced Light Source at Berkeley Lab, Spallation Neutron Source at Oak Ridge, as well as plans to use Linac Coherent Light Source at Stanford, National Synchrotron Light Source-II at Brookhaven and other facilities in US and Europe.

Our group's research is generously supported by Department of Energy (Basic Energy Sciences), National Science Foundation (CAREER), Air Fource Office of Scientific Research, Argonne LDRD and Hellman Foundation.
