I joined LSBU in 2020, where I am Newton International Post-Doctoral Fellow in the School of Engineering. I originally studied Master in Nanotechnology, completing at AMU Aligarh India, followed by a PhD in Materials Science and Engineering from the Indian Institute of Technology Kanpur, Kanpur, India. My main research interests are nanomaterials preparation and their characterisations, Thermal spray coating and molecular dynamics.

I have worked in the multi-disciplinary research area before joining LSBU, worked as a Kreitman Foundation post-doctoral fellow at Ben Gurion University of Negev, Israel, for one year and worked on measuring nanomechanical properties of virus capsid using advanced AFM nanoindentation technique in physiological condition (in-situ). During doctoral studies, prepared high entropy alloys nanoparticles, which are almost impossible to synthesise by wet chemical synthesis due to different reaction rates of different metals and due formation of intermetallic, cause losing the high entropy single phase properties. I have discovered a novel process to prepare the HEA alloys nanoparticle synthesis process by cryomilling and preparing three types of HEA nanoparticles (FeCrMnNiCo, FeCrMnVAl, and AgAuCuPdPt) successfully. The AgAuCuPdPt shows promising catalytic activity for CO2 reduction to hydrocarbon fuel. Based on this result, one published in ACS-Catalyst and another published in Materials Today Energy. One review article on cryomilling as a green process for nanomaterials preparation and its prospects published in International Materials Review. I have published around 20 research articles, one book chapter on nanomaterials utilisation in bio-sensors, and one Indian patent.

I have hands-on experience (Transmission electron Microscopy) for different samples (solid bulk sample, powder sample, etc.) on a double tilt GATAN holder. I am an expertise bright field, dark field, diffraction pattern in different zone axis, HAADF imaging, and image processing software (GATAN Digital microscopy suit). I have expertise in various characterisation instrument like XRD, SEM, UV-Visible, Raman spectroscopy, nanoindentation.
