We use optical and electron spectroscopies to study electronic properties of strongly correlated materials. Those include high temperature superconductors, novel conventional superconductors and heavy fermion systems. They are not only technologically relevant, but also display range of fascinating physical properties. Our goal is to understand how the electronic excitations give rise to these highly unusual properties.

Design, discovery, growth and characterization of novel materials - often in single crystal form - and study of their interesting physical properties.
Microscopic characterization of magnetic and electronic properties of strongly correlated electron systems (low dimensional quantum spin system, nanoscale molecular magnets, Fe-based superconductors and related materials) by using Nuclear Magnetic Resonance (NMR) technique at very low temperatures (down to 50 mK) and high pressure (up to 25 kbar).

Low dimensional nanoscale structures (graphene, metals on graphene, ultrathin metallic films, nano islands, nanowires, etc.).
We utilize the concepts and methods of non-equilibrium statistical physics and multiscale modeling to develop predictive models and simulation algorithms for a range of physical, chemical, and materials systems.
Focus areas and applications include: (i) growth and relaxation of epitaxial thin films and nanostructures; (ii) spatio-temporal behavior in catalytic surface reactions; (iii) transport and reaction in mesoporous systems; (iv) non-equilibrium phase transitions in reaction-diffusion systems.

Synthesis, characterization and physical property measurements of polycrystalline and single crystal samples of materials with interesting properties and ground states, including cuprate and FeAs- based high temperature superconductors and related materials, low- dimensional magnetic insulators, and d-electron heavy fermion compounds.
Development of theoretical tools to study a broad range of problems in physics, materials science, and chemical as well as biological systems. Current efforts include (1) methods for accurate calculation of correlated electron systems; (2) methods for spin dynamics and quantum control of spin; and (3) methods for computational prediction and design of complex structures and materials.
