Summary
I am a Research Associate at the University of Sheffield in Prof. Russell Goodall’s group, working on the EPSRC-funded SURFACTANT project (Oct 2025 – Present). I design, produce and characterise novel solder alloys to enable flux‑free, repairable and recyclable joints for multi‑material EV battery assemblies. My work examines solder wetting on laser‑textured surfaces and builds composition–microstructure–property links using alloy design, vacuum melting, SEM/EBSD and XRD.
Previous projects
- Mechanical Properties of Battery Materials — University of Sheffield, FutureCAT (Oct 2023 – Sep 2025). Mechanically characterised cathode materials using in‑situ nano‑indentation (Alemnis) and micro‑computed tomography to analyse 3D electrode microstructure, defect content and resilience; linked composition, cation‑ordering and electrochemical history to mechanical behaviour for next‑gen battery optimisation.
- LightForm: Crystal Plasticity for Warm Forming — University of Manchester (Nov 2022 – Oct 2023). Extended crystal plasticity in DAMASK, coupling with phase transformation and dynamic precipitation to better describe deformation during warm forming; advanced understanding of light‑alloy formability under industrially relevant conditions.
I hold a joint M.Tech–Ph.D. (IIT Kanpur). My interests span alloy design, advanced characterisation, micromechanics and computational materials, with a focus on sustainable manufacturing and energy applications.
