Dr. Gourav Bhattacharya is a Research Associate at Ulster University, UK, specializing in nanotechnology, surface and interfacial science, electrochemistry, and advanced materials characterization. He completed his Ph.D. in Physics from Shiv Nadar University (2019) and was awarded the prestigious Commonwealth Split-Site Scholarship, which supported collaborative research in the UK. His research focuses on carbon nanomaterials, functional nanostructures, and advanced materials for energy storage and sensing applications. He works on graphene-based systems, sustainable nanomaterials derived from industrial waste, wearable biosensors, and energy harvesting devices. He also develops and applies advanced microscopy and nanoscale characterization techniques, including multifrequency atomic force microscopy (AFM), for sensing, imaging, and micro- and nanomanipulation studies. His recent work extends into emerging quantum-enabled sensing platforms. Dr. Bhattacharya has authored 48 peer-reviewed journal publications with over 1,580 citations (h-index 23). He serves as a Part-Time Lecturer in Analogue and Digital Electronics and is an Associate Fellow of the Higher Education Academy (AFHEA), UK. His work bridges fundamental materials physics with translational applications in sustainable energy and healthcare technologies.
