Dr. Dinesh Veeran Ponnuvelu is an accomplished researcher and academic with interdisciplinary expertise spanning nanoscience, precision sensors, MEMS/NEMS device fabrication, and smart agricultural technologies. With a strong foundation in agriculture and advanced training in nanotechnology, his research uniquely bridges fundamental nanoscale material science with real-world applications in environmental monitoring, healthcare diagnostics, and precision farming. He currently serves as Associate Professor at the School of Agricultural Sciences, Dhanalakshmi Srinivasan University, India, and has held prestigious international research positions in South Korea and Israel, reflecting the global relevance and impact of his work. Dr. Dinesh’s core research focuses on the synthesis, characterization, and functional integration of hetero-nanostructured materials, particularly metal oxide–based core–shell and heterojunction nanostructures. These materials are engineered to achieve enhanced sensitivity, selectivity, and low-temperature operability for gas sensing applications. His pioneering contributions in plasmonic nanostructures (ZnO@Ag, ZnO@Au, TiO₂–Au, graphene-supported systems) have advanced trace-level detection of environmentally and clinically important gases such as NO₂ and NH₃. He has also made significant progress in understanding spill-over sensitization, surface defect engineering, and nano-contact optimization for high-performance chemiresistive sensors. His recent work integrates microfluidics, 3D printing, and bio-inspired nanosystems to develop low-cost, portable, and scalable diagnostic devices, including breath analyzers and biomedical sensing platforms. These efforts align strongly with sustainable development goals, particularly in healthcare accessibility, food safety, and environmental protection.
