Vishakha Sharma is a researcher working in the broad area of nanophotonics and metasurface-based light manipulation, with special focus on chiral metasurfaces, polarization and spin-dependent photonics, tunable optical devices and non-Hermitian photonics. She completed her Ph.D. in Applied Physics from Delhi Technological University (DTU) in 2026, building on her academic background in Physics, with an M.Sc. in Physics and a B.Sc. (Hons.) in Physics from the University of Delhi.

Her research focuses on the design and investigation of advanced chiral and multifunctional metasurfaces for controlling the fundamental properties of light, including its amplitude, phase, polarization, and spin. Her doctoral work involved the development of plasmonic and dielectric metasurface platforms exhibiting enhanced circular dichroism, polarization-selective optical responses, and multifunctional light manipulation.

Her research has also explored active and electrically tunable metasurfaces, including graphene-integrated photonic structures, enabling dynamic control of optical responses. More recently, her work has expanded toward non-Hermitian photonics and exceptional-point phenomena in chiral metasurfaces, focusing on the evolution of eigenmodes, polarization-dependent responses, chirality, and non-Hermitian degeneracies.

Her broader research interests include active and reconfigurable metasurfaces, exceptional-point physics, optical sensing, secure optical communication, optical information processing, and advanced nanophotonic devices. Her research contributions have resulted in several peer-reviewed publications in reputed international journals, presentations at international conferences, and intellectual property development in metasurface-based photonic technologies.
