Deb Roy

Dr. Deb Roy is a Senior Lecturer in Chemistry at Swansea University's School of Engineering and Applied Sciences. With a distinguished career spanning over two decades, Dr. Roy has established himself as a leading researcher in nanospectroscopy and nanomaterials science. His work bridges fundamental research with clinical applications, particularly in cancer diagnostics.

• Materials Science degree from Indian Institute of Technology, Kharagpur
• PhD in Raman Spectroscopy of Carbon Nanostructures from University of Cambridge
• Researcher at Prof. Sir Mark Welland's Nanoscience Centre, Cambridge (2003-2005)
• Technical lead at National Physical Laboratory (2005-2017)
• Senior Lecturer at Swansea University (2017-present)

Dr. Roy's research focuses on advanced spectroscopic techniques for nanoscale analysis, with particular emphasis on Raman spectroscopy applications. His work spans fundamental nanomaterials characterization to clinical diagnostic applications, demonstrating exceptional versatility. The research group has pioneered techniques in tip-enhanced Raman spectroscopy and developed innovative approaches for cancer detection using vibrational spectroscopy. Dr. Roy has made significant contributions to standardization in Raman spectroscopy and established international conferences in the field.

Recent publications reveal a strategic shift toward medical applications, particularly in early cancer detection using FTIR and Raman spectroscopy. While maintaining strong foundations in 2D materials characterization (graphene, MoS2), the research has increasingly focused on clinical diagnostics, especially pancreatic and oral cancers. This represents a successful translation of nanoscale analytical techniques to solve critical healthcare challenges.

• Multiple best paper awards during National Physical Laboratory tenure
• Initiated international standardization for Raman spectroscopy
• Founded international conference on tip-enhanced Raman spectroscopy
• Regular invited talks at major scientific conferences

Dr. Roy actively supervises multiple PhD and MSc students across interdisciplinary projects spanning chemistry, engineering, and medical diagnostics. His research group collaborates extensively with clinicians and industry partners, securing funding for projects at the intersection of nanotechnology and healthcare. The supervision portfolio demonstrates strong connections with Swansea University's medical research community, particularly in cancer diagnostics.

The research group maintains state-of-the-art laser analytics and nanoscience facilities, supporting both fundamental materials research and clinical applications. The laboratory infrastructure enables cutting-edge work in nanoscale spectroscopy, with equipment tailored for both materials characterization and biomedical analysis.
