Dr
Dr. Rajani Vijayaraghavan is an assistant professor in the School of Electronic Engineering at Dublin City University and a funded investigator in the I-Form Advanced Manufacturing Research Centre.
Rajani holds an M.Sc. in Physics and a Ph.D. in Materials Science and Engineering. Her doctoral research focused on the development of novel materials and devices for energy and optoelectronic applications. Rajani has extensive expertise in plasma-based technologies for advanced materials synthesis, processing, surface functionalization, and nanofabrication. She is particularly recognized for her work with copper halide-based materials in semiconductor, optoelectronic, and solar cell applications. She has led several projects and innovations including the development of smart wearable devices for personal and occupational UV monitoring (EI-commercialization fund), the pulsed plasma-PVD technology development for large area graphene growth, and the application of PVD-graphene for anticoagulation areas.
Her research interests lie broadly in the fields of functional materials and devices, with applications in optoelectronic, sensing, and energy technologies. She specializes in developing thin films and coatings with unique optical and electrical properties. Recently, she has expanded her research to include smart shape memory materials for MEMS and soft robotics applications.
