Dr Deb Roy

Senior Lecturer, Chemistry
Available For Postgraduate Supervision


I obtained my first degree in Materials Science from Indian Institute of Technology, Kharagpur (India) and PhD on Raman Spectroscopy of Carbon Nanostructures from University of Cambridge (UK).

 In 2003 I joined Prof. Sir Mark Welland’s Group in Nanoscience Centre, Cambridge (UK) and developed a prototype super-resolution Raman spectroscopy and imaging system in reflection mode.

 In 2005, I joined the National Physical Laboratory to establish a technical area on Analytical and Optical Nanoprobes to develop measurement science to position the UK for emerging bio nanotechnologies. During this period, I received several awards for best papers, initiated the international standardization for Raman spectroscopy and started the international conference on tip-enhanced Raman spectroscopy. I have regularly given invited talks in international scientific conferences as well as industrial meetings.

 In 2017 I joined Swansea University to build research activities on laser analytics and nanoscience. Areas of interest includes nanobiotechnology, advanced materials and sensors.
