In recent years, the ability to synthesize, engineer & observe materials on the nanometer length scale has led to novel phenomena and applications. On the other hand, modern lasers deliver powerful, ultra short pulses of light allowing us to observe the interaction of electrons and atoms on the femtosecond timescale. Together, these technologies allow us to study new paradigms in light-matter interaction – with femtosecond temporal resolution and nanometer spatial resolution. In the Femtosecond Spectroscopy Unit, we direct these abilities towards four main research thrusts:
- Novel 2D Materials and Heterostructures, where we search for new functionality and physics in two-dimensional materials and their heterostructures;
- Terahertz Applications and Devices, where artificially nano-engineered devices generate and manipulate low energy electromagnetic radiation;
- Techniques for Neuroscience & Drug Delivery, where femtosecond pulses trigger nanoscale devices to interface with neural functioning; and
- Energy Materials, where the ultrafast dynamics of photoexcited electrons and holes influence the ability to harness solar energy.

As the Femtosecond Spectroscopy Unit, we are a team of young, energetic researchers relishing the OIST-adventure in Okinawa - a beautiful tropical island in the Pacific. We come from a variety of countries and cultures, with a diverse set of research interests and hobbies. Currently, we come from the UK, Greece, Japan, Malaysia, India and the US. Some of us love biking, motorcycling, cricket, ice hockey, and traveling; and apparently all of us love eating! Professionally, our interests overlap at Condensed Matter Physics and Ultrafast Spectroscopy, while also extending to Cosmology, Mathematics and Atomic Physics. We each bring our relevant expertise, be it in experimental ultrafast spectroscopy, theory or device fabrication to complement our team. We enjoy collaborating with other OIST-ers as well as researchers in far-off exotic locations like Paris, Berlin and Houston. We welcome you to learn more about each of us in the Members tab on the left. We look forward to telling you about our Okinawan adventure, and in turn getting to know you...when you visit us in Okinawa!
