Krishnan Kundan is currently pursuing his Ph.D. at the Optics and Photonics Centre (OPC), IIT Delhi, with research interests in optics, photonics, non-Hermitian physics, and advanced optical sensing. His research focuses particularly on Photonic Time Crystals (PTCs) and their emerging applications in highly sensitive optical systems.

His research work investigates wave propagation in time-periodically modulated photonic media, with particular emphasis on Floquet dynamics, non-Hermitian effects, and the formation of exceptional points (EPs).

His current work focuses on exceptional-point dynamics in Photonic Time Crystals for enhanced optical sensing, combining analytical modeling, numerical simulations, and quantum-noise analysis. He is investigating sensing performance using quantities such as Fisher information and the Cramér–Rao bound (CRB) to understand the fundamental limits of parameter estimation in non-Hermitian photonic system.
