Demetrios Christodoulides

Demetrios Christodoulides is a Professor at the University of Southern California (USC), holding dual appointments in the Department of Electrical and Computer Engineering and the Department of Physics and Astronomy within the USC Dornsife College of Letters, Arts and Sciences. His research focuses on nonlinear optics, topological photonics, and the thermodynamic behavior of light in complex systems. He explores phenomena such as solitons, thermalization in multimode optical fibers, and non-Hermitian systems, with applications to advanced photonics and quantum technologies.

• Key areas: Nonlinear dynamics, photon thermodynamics, topological insulators, ultrafast optics, and optical lattice engineering.
• Notable contributions include pioneering work on spatiotemporal wave packets, Joule-Thomson photon-gas expansion, and Floquet topological phases.

His work bridges theoretical and experimental photonics, with implications for optical communication, quantum information, and light manipulation. Recent studies investigate thermalization in multimode systems, non-Hermitian skin effects, and Lagrangian-based light guidance.
