In my thesis, I mainly focus on utilizing ultrafast optical and THz spectroscopy to study phase transition dynamics as well as electron-phonon coupling in high quality V2O3 and VO2 thin films on different substrates. I also discuss the possibility of multiple routes for inducing the insulator to metal transition with ultrafast pulses at different photon energies.
