Research Summary

Assistant Professor, Department of Physics, MIT (01/08 - present)
Ultrafast electronic and structural dynamics in quantum materials: We are developing and using advanced optical techniques for investigating fascinating properties of quantum materials such as high Tc superconductors and topological insulators. Experimental techniques include ultrafast electron diffraction, time and angle resolved photoemission spectroscopy, pump-probe spectroscopy, transient grating spectroscopy and time domain terahertz spectroscopy.

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.
