Nihar Ranjan Sahoo is a Postdoctoral Researcher working on tunable polaritonic materials and twisted metasurface structures under the MURI program. His current research focuses on isotope-engineered van der Waals crystals, plasmonic meta surfaces, and phononic moiré superlattice platforms for enhanced light–matter interactions. Nihar received his Ph.D. in Physics from the Indian Institute of Technology (IIT) Bombay, where his work explored infrared photonics using in-plane hyperbolic van der Waals crystals.
