Rate My Professor Deb Roy

Dr Deb Roy is a Senior Lecturer in Chemistry at Swansea University. He obtained his first degree in Materials Science from the Indian Institute of Technology, Kharagpur, India, and his PhD in Raman Spectroscopy of Carbon Nanostructures from the University of Cambridge, UK. In 2003, following his doctorate, he joined Professor Sir Mark Welland’s Group at the Nanoscience Centre in Cambridge, where he developed a prototype super-resolution Raman spectroscopy and imaging system in reflection mode. In 2005, he moved to the National Physical Laboratory, establishing a technical area on Analytical and Optical Nanoprobes to advance measurement science for emerging bio-nanotechnologies. During his tenure at the National Physical Laboratory, he received several awards for best papers, initiated the international standardization for Raman spectroscopy, and started the international conference on tip-enhanced Raman spectroscopy. He has regularly delivered invited talks at international scientific conferences and industrial meetings. In 2017, Dr Roy joined Swansea University to build research activities in laser analytics and nanoscience.

Dr Roy's research specializations include Raman spectroscopy, tip-enhanced Raman spectroscopy, graphene and 2D materials, coherent Raman imaging of biological systems, sensors, and digital molecular diagnostics, with key interests in nanobiotechnology, advanced materials, and sensors. His contributions have advanced nanoscale optical techniques for materials characterization and biomedical applications. Notable publications comprise 'Intervalley scattering by acoustic phonons in two-dimensional MoS2 revealed by double-resonance Raman spectroscopy' in Nature Communications (2017), 'Simultaneous topographical, electrical and optical microscopy of optoelectronic devices at the nanoscale' in Nanoscale (2017), 'Extending the plasmonic lifetime of tip-enhanced Raman spectroscopy probes' in Physical Chemistry Chemical Physics (2016), 'Nanoscale mapping of excitonic processes in single-layer MoS2 using tip-enhanced photoluminescence microscopy' in Nanoscale (2016), and 'Nanoscale mapping of intrinsic defects in single-layer graphene using tip-enhanced Raman spectroscopy' in Chemical Communications (2016). At Swansea University, he teaches modules including Reactions and Products, Chemical Practice, Analytical Chemistry, Advanced Topics in Physical Chemistry, and Chemistry Project, and supervises PhD and MSc students on projects such as early pancreatic cancer detection using spectroscopy and in-situ electrochemical spectroscopy.
