- Developed a multi‑physical model to understand magnetic ageing in Fe‑Si electrical steels, linking pre‑strain, precipitation kinetics, and iron‑loss behaviour. - Performed tensile tests, SEM/EBSD/TEM analysis, DIC, thermal ageing, and magnetic measurements to validate microstructure–property mechanisms. - Improved prediction accuracy of iron losses and contributed to more reliable, energy‑efficient electrical machine design. - Investigated effects of forging, rolling, and cutting on magnetic degradation t

- Studied crack initiation and propagation in A319 alloy using in‑situ optical microscopy and DIC. - Compared Lost Foam Casting and Die Casting microstructures to identify porosity and intermetallic phases affecting failure. - Performed nano‑indentation and micro‑tensile tests to characterize local mechanical behavior. - Delivered insights to improve casting quality and extend component life in automotive engine applications.

- Designed and analysed a hydrogen microturbine using Abaqus for high‑temperature applications. - Conducted long‑duration creep simulations (5000h) for CMSX‑4+ blades and N18 disks to assess structural integrity. - Supported material selection and design decisions for advanced turbine systems.

- Estimated fatigue life of Inconel specimens produced via laser powder bed fusion. - Performed FEM simulations to study porosity interactions in electron‑beam‑welded titanium alloys. - Provided microstructure‑mechanics insights to support additive manufacturing and welding process optimization.

- Finite element computation to Understand interaction between porosities in electron beam welding junction in Titanium alloys. - Analysed the effect of porosities size and density on monotonous load and fatigue conditions.
