Our group focuses on Ultrafast phenomena in solids. We are particularly interested in the charge, spin and phonon dynamics in condensed matter systems.
Some of the areas that we are currently working on are:
Ultrafast optical studies of emergent material systems (eg. TMDCs, perovskites and strongly correlated materials)
Light-matter interaction in acoustic cavities
Terahertz spectroscopy and imaging (for fundamental studies as well as industrial applications)
