My main research interest is photonics at a nanoscale. Particularly, I numerically and experimentally study phase-change material-based tunable photonic integrated circuits as well as metasurfaces. In the future, I envision these scale up and work in a wafer-scale, facilitating applications such as optical in-memory computing.
