Biography

Biography

Marian Florescu joined the University of Surrey in 2011. He graduated from the University of Bucharest with a BSc in Physics and then obtained his PhD in Theoretical Quantum Optics at the University of Toronto. Prior to joining the Physics Department at Surrey he was a Research Scholar and Lecturer at Princeton University and a National Research Council Research Associate at NASA Jet Propulsion Laboratory. His current activities are focused on the physics and applications of non-crystallographic photonic band gap materials, thermal radiation control in photonic materials and quantum optics in structured photonic reservoirs.
