About

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.

Taught Modules

CH-127 Chemical Practice

This module will introduce students to the three broad employment areas for chemistry: research, teaching or industrial positions. The lecture portion will cover fundamental aspects of being a professional chemist including safety, report writing, project management, and teaching skills. Students will attend research seminars and workshops, industrial field trips, and supervise school pupils in the laboratory. Assessment will be by coursework and a written report.
CH-241 Analytical Chemistry

This course will cover theory and applications of qualitative and quantitative analytical chemistry, with particular emphasis on quantitative chemical analysis. The students will learn about various processes and measurements involved in a chemical analysis, and about statistical analyses of the data acquired during such experiments. The topics related to both classic (e.g., titrations) and modern analytical techniques (e.g., spectroscopy, surface analysis) will be covered. Material, techniques and skills covered in the course of this module will build on and therefore require understanding of all prior modules. The module will be assessed by coursework (a presentation, laboratory experiments, laboratory report and assignments) and by examination.
CH-342 Advanced Topics in Physical, Instrumental and Analytical Chemistry

This module completes the core aspects of Physical Chemistry for the undergraduate programme, applying existing understanding of thermodynamics and quantum mechanics to connect the quantum world with the observable world in Statistical Mechanics and relating quantum understanding to the application of light in chemical reactions. Laboratory experiments will be fully investigative, with students carrying out advanced `mini projects¿ to initiate and guide students in elementary research skills in preparation for their research projects. Material, techniques and skills covered in the course of this module will require understanding of prior modules.
CH-344 Chemistry Project

3rd year projects are the opportunity to bring all you've learnt during your degree together and apply that knowledge to solve a problem. In Swansea these projects can be embedded in active research groups across the colleges of science, engineering or medicine, allowing you to build a network and experience in your chosen specialism within the chemical sciences. These projects are your opportunity to demonstrate to employers that you have a full understanding of your course and are able to direct your own studies, manage an independent research project and effectively communicate your findings. This selection suggests an interest in a project embedded within a research group in engineering, focusing on materials chemistry or chemical engineering
CH-349 Integrated Topics in Chemistry

This module gives students the opportunity to explore options within Chemistry, giving opportunity to apply prior learning to advanced research topics and allowing students to pursue more specialised topics related to their research interests and aligned with the research areas represented within the Department. Study areas available will include advanced spectroscopic techniques, the application of instrumentation in chemistry, as well as more advanced synthetic pathways and a return to more integrated study of the traditional branches of organic/inorganic/physical chemistry. The module will also include a mandatory employability component. Classes will be supported with workshops which will help students gain a thorough understanding of the integrated nature of Chemistry at an advanced level. Where possible, topics will be taught using relevant examples from primary literature, encouraging students to evaluate and appraise a range of primary literature sources and locate appropriate new sources. The module is designed to be flexible to allow the content to vary with the research areas represented within the Department and wider university.
CH-409 MChem Research Project

MChem projects are the defining feature of the integrated masters with a chance to contribute research work of potentially publishable standard to an active research group within the University. In Swansea these projects can be embedded in active research groups across the Faculty of Science and Engineering or the Faculty of Medicine, Health and Life Science, allowing you to build a network and experience in your chosen specialism within the chemical sciences. These projects are an excellent way of managing the transition on to your next destination after undergraduate study, whether that is a postgraduate research studentship or into employment. The skills developed in the MChem projects demonstrate the ability to successfully deliver all aspects of a 60 credit research project and on exit you will have demonstrated the academic equivalence and begun developing the other skills required for entry into professional development schemes leading to chartership. This selection suggests an interest in a project embedded within a research group in science, focusing on straight chemistry, or interacting and collaborating with another department such as bioscience, geography, physics, maths or computer science.
CH-413 Advanced Integrated Topics in Chemistry Part 2

This module gives students the opportunity to explore options within Chemistry, giving opportunity to apply prior learning to advanced research topics and allowing students to pursue more specialised topics related to their research interests and aligned with the research areas represented within the Department. Study areas available will include advanced spectroscopic techniques, the application of instrumentation in chemistry, as well as more advanced synthetic pathways and a return to more integrated study of the traditional branches of organic/inorganic/physical chemistry. Classes will be supported with workshops which will help students gain a thorough understanding of the integrated nature of Chemistry at an advanced level. Where possible, topics will be taught using relevant examples from primary literature, encouraging students to evaluate and appraise a range of primary literature sources and locate appropriate new sources. The module is designed to be flexible to allow the content to vary with the research areas represented within the Department.
