Research efforts of the Ultrafast THz and Optical Spectroscopy Lab at WPI (PI- Lyubov Titova) are focused on three themes: (i) Application of terahertz (THz) spectroscopy to probe dynamics of photo-excited charge carriers in nanomaterials with applications in photovoltaics and solar fuel production; (ii) Using THz pulses and ultrafast optical techniques to study intermolecular dynamics in liquids; (iii) Investigating interactions of intense THz pulses with cells, tissues and their constituents, with a goal of development of novel diagnostic and therapeutic applications. Prof. Titova is a member of WPI Energy Research Group http://energy.wpi.edu
