Ultrafast THz and Optical Spectroscopy Lab (PI: Titova) explores light–matter interactions in emerging functional materials. Our research focuses on nanomaterials, including two-dimensional (2D) materials such as MXenes, MXene–biopolymer composites, and layered semiconductors. Using ultrafast optical and THz spectroscopy, we uncover how nanoscale structure and interfaces control electrical transport and optical and thermal properties. Spanning solid-state physics, nanomaterials, and photonics, our interdisciplinary research bridges fundamental discoveries with applications in photonics, flexible electronics, quantum materials, and biointegrated technologies through collaborations across WPI and with academic and industrial partners.
