Research Summary
Assistant Professor, Department of Physics, MIT
(01/08 - present)
Ultrafast electronic and structural dynamics in complex materials:
We are developing and using advanced optical techniques for investigating
ultrafast processes in complex materials. Experimental techniques include
ultrafast electron diffraction, pump-probe and transient grating spectroscopy
and time domain terahertz spectroscopy. We are especially interested
in using these techniques to understand fascinating properties of strongly
correlated electron systems such as cuprate superconductors.
Postdoctoral Researcher, Prof. Ahmed Zewail Group, Caltech (07/04
- 01/08)
Structural dynamics in solids and at interfaces with atomic-scale
resolution: Used ultrafast electron diffraction (UED) to investigate
structural dynamics in solids, nanostructures and interfacial molecular
assemblies. Specific systems studied include cuprate superconductors,
GaAs quantum well structures and interfacial water assemblies at hydrophobic
and hydrophilic surfaces. UED can provide ultra-short spatial resolution
(0.1 to 1nm) combined with ultrafast time resolution (10-13
to 10-12 s) with sub-monolayer sensitivity.
Graduate Student Researcher, Prof. Joseph Orenstein Group, UC
Berkeley (05/99 - 05/04)
Quasiparticle dynamics in high temperature superconductors:
Developed a novel transient grating spectroscopy setup and measured
diffusion coefficient of nonequilibrium quasiparticles in high temperature
superconductors for the first time, obtained elastic and inelastic quasiparticle
scattering rates using ultrafast optical spectroscopy. Optical manipulation
of spins in quantum wells: Used transient spin grating spectroscopy
to measure spin diffusion in quantum wells and for the first time observed
spin Coulomb drag (SCD) by showing that spin diffusion is smaller than
charge diffusion as a result of electron-electron interactions in excellent
quantitative agreement with SCD theory.
