Biomolecular systems properties investigation using various techniques including fluorescence, ATR/FTIR, THz-TDS, ForteBio Octet, Biacore, ELISA, uv-visible, circular dichroism, DSC, and light scattering.
Developed anisotropic THz near field microscopy techniques to measure intramolecular vibrations of proteins, particularly photoactive yellow protein, orange carotenoid protein and FMO.
Designed and implemented one-color and two-color pump-probe techniques using electro-optic (EO) crdsytals (BBO/LBO) and a regenerative amplifier Ti-sapphire system (Spectra-Physic) in 1 kHz repetitive rate. Designed and implemented time-domain terahertz spectroscopy using EO crystals (ZnTe/GaP) Designed and conducted time domain terahertz spectroscopy using antennas.
Developed and fabricated optoelectronic semiconductor devices based on 2DEG, quantum-wells/dots, and 2D layered materials for IR and/or THz photoconductive detector. Tested device performance by optimizing electric/optical characterizations including gate control and pump-probe UV/vis/THz spectroscopy.
