Biography

Prof. Awasthi is a distinguished academician and researcher in the field of photonic crystals and optical sensing devices. Currently serving as Associate Dean (Student Welfare & Administration) and faculty member at JIIT, Noida, he has made significant contributions to the theoretical and computational modelling of one-dimensional photonic crystals, plasmonic sensors, and tunable optical filters. His research primarily focuses on the design and analysis of novel photonic structures for biomedical and environmental sensing, leveraging properties like photonic bandgap, refractive index sensitivity, and defect mode tuning.

Prof. Awasthi’s recent work includes publications in highly reputed SCI-indexed journals such as Scientific Reports, RSC Advances, Crystals, Physics of Plasmas, Materials, and Journal of the Optical Society of America B. His recent research explores plasmonic chemical sensors using black phosphorus and Al₂O₃, as well as the use of defective photonic crystals for malaria detection, including the detection of women's reproductive hormones, brain tumor diagnostics, and polluted water analysis using photonic crystal-based sensors. His studies also cover topics such as omnidirectional filters, tunable multichannel structures, and metamaterials involving superconductors and cold plasma.

Earlier in his career, he delved into filter performance in magnetized plasma structures, infrared omnidirectional mirrors using birefringent–dielectric materials, and entanglement dynamics in qubit–qutrit systems. Many of his papers have been published in journals like Quantum Information Processing, Superconductivity, J. Modern Optics, and Physica B. His scholarly output has earned him over 1365 citations and an h-index of around 39.

Prof. Awasthi holds an M.Sc. degree in Electronics from the University of Lucknow and earned his doctorate with a thesis on optical devices based on photonic crystals. Prior to joining JIIT in 2010, he served as a faculty at University of Lucknow, Amity University Jaipur and Amity University Noida from 2003 to 2010. Prof. Awasthi is known for his rigorous approach to research and commitment to mentoring students, Prof. Awasthi continues to push the frontiers of photonic and plasmonic sensor technologies.
