Dr. Devesh Barshilia is an emerging multidisciplinary scientist whose research spans biosensors, nanophotonics, optofluidic platforms, semiconductor optoelectronics, and integrated photonic sensing systems, positioned at the intersection of materials science, photonics, and biomedical engineering to develop high-performance, low-cost, and ultra-sensitive detection technologies for healthcare, environmental monitoring, and analytical diagnostics. A major focus of his work is the design and optimization of planar waveguide–based optofluidic sensors for rapid, real-time, and label-free refractive index detection, with his highly cited publication on waveguide sensors highlighting his strong impact in optical detection research. He has also made notable advances in particle plasmon resonance integrated biosensing by synergizing plasmonic field enhancement with guided-wave optics to achieve superior biochemical sensitivity, while his contributions to guided-mode resonance (GMR) biosensing demonstrate his ability to engineer compact, precise, and clinically relevant optical devices. His work on nanogold-linked immunosorbent assays is especially impactful, enabling improved early detection of sepsis-associated biomarkers such as procalcitonin for point-of-care diagnostics. Parallel to his biosensing developments, Dr. Barshilia has produced influential research in semiconductor photonic devices including GeSn-based short-wave infrared phototransistors, graphene-based flexible photodetectors, and engineered silicon-dioxide nanostructures, with publications in leading journals such as Optics Express, Optics Letters, Advanced Optical Materials, and Nano Letters. By integrating waveguide-enhanced spectroscopy, nanoplasmonics, and advanced biosensing microarchitectures, he is advancing miniaturized diagnostic tools for DNA, protein, and biomarker detection. With 183 citations, an h-index of 6, and a steadily expanding publication record, Dr. Barshilia is establishing himself as a rising contributor to next-generation biosensing and integrated photonic diagnostics.
