Prof. Arka Mandal's research focuses on the deformation behaviour of metallic materials across length scales, from bulk response to nanoindentation, with emphasis on crystalline defects [1], solid-state phase transformations, and the processing-structure-texture-property correlation in steels. He employs advanced electron microscopy and related characterization techniques [2] to reveal the role of defects, interfaces, and microstructural evolution in governing mechanical behaviour. His work integrates experimental analysis with a fundamental understanding of deformation and transformation mechanisms to build structure-sensitive insights for metallic systems. A strong focus of his research is on steels, where texture evolution [3] and phase stability are linked to performance under service conditions. Overall, his research aims to connect microstructural features with macroscopic properties for the design of stronger, more reliable engineering materials.

Prof. Abhinandan Gangopadhyay is interested in applying advanced electron microscopy techniques to study defects and interfaces in advanced functional and structural materials. He has previously studied the core structure of various interfacial defects such as dissociated 60° dislocation [1], Lomer dislocation [2], dissociated 90° dislocation [3] in GaAs(001)­based heterostructures using high­angle annular­dark­field (HAADF) mode of aberration­corrected scanning transmission electron microscopy (AC­STEM). Prof. Gangopadhyay has also worked on STEM­EDX characterization of grain boundary segregation in novel polycrystalline GaInP solar cells. As part of his recent industrial work experience, he has worked on nanometer­scale characterization of state­of­the­art semiconductor devices using focused ion beam (FIB) technique in conjunction with AC­STEM. His current research interests include segregation studies using STEM spectrum images and strain mapping using geometric phase analysis (GPA) and 4D STEM in advanced materials.
