Research Interest:

Ultrafast dynamics in condensed matter systems using femtosecond pump-probe spectroscopy and time and frequency resolved terahertz (THz) spectroscopy. The pump and probe pulses range from UV, VIS, IR and THz wavelengths. Nonlinear response of the condensed matter will be investigated using femtosecond pulses in this electromagnetic region. Some examples of excellent candidates to use THz and femtosecond pulses are 2D systems like 2DEG/2DHG, 2D layered materials, topological systems, solar cells, strongly correlated systems and artificially created metamaterials. Another direction of my interest is to study possible damage to biological systems due to intense THz pulses and THz imaging of biological systems and superconductors.
