Desigan R (2021-)
Desigan's research is directed toward the systematic design and fabrication of multilayer and bilayer polymer thin-film systems, with a primary focus on understanding and tailoring their viscoelastic behaviour at small length scales. His work involves detailed experimental investigations aimed at extracting intrinsic viscoelastic properties of polymer layers deposited on mechanically inaccessible substrates, where direct mechanical characterization is inherently challenging.
He performs comprehensive nanoindentation-based studies to examine the depth- and temperature-dependent viscoelastic response of these polymer architectures, including time-dependent deformation and relaxation phenomena. In parallel, he undertakes rigorous theoretical analyses of viscoelastic models to support experimental findings, thereby establishing quantitative structure–property relationships that link multilayer architecture, thermal effects, and mechanical reliability in polymer thin-film systems.

Sachin Varma (2022-)
Sachin’s research focuses on the development of advanced polymer nanocomposites with an emphasis on their mechanical performance, antibacterial functionality, and biocompatibility. His work explores the incorporation of functional nanofillers, including sustainable materials such as rice husk ash, to enhance the mechanical and functional properties of polymer matrices for biomedical and environmental applications.
A key component of his research involves the evaluation of cytotoxicity and cell material interactions to assess the suitability of these nanocomposites for biomedical use. In parallel, he investigates time-dependent mechanical behaviour, including creep, strain-rate sensitivity, and stress relaxation, particularly in polymers used for denture and prosthetic applications. These studies employ nanoindentation-based characterisation coupled with viscoelastic modelling to optimise mechanical reliability under realistic service conditions. Beside his research, Sachin nurtures a passion for football and music, with a special interest in playing percussion instruments.
Shubha A (2024-)
Shubha’s research is centered on the rational design and development of advanced polymer composite materials for electromagnetic interference (EMI) shielding applications, with a strong emphasis on achieving lightweight, flexible, and mechanically robust systems. Her work systematically investigates the incorporation of functional fillers into polymer matrices to enhance electromagnetic wave attenuation, while preserving the intrinsic advantages of polymers such as processability, structural integrity, and adaptability to large-area fabrication.
The research places particular emphasis on absorption-dominated EMI shielding mechanisms operating in the GHz frequency range, elucidating the roles of dielectric polarization, interfacial losses, and multiple scattering arising from well-engineered filler–matrix interfaces. Through controlled optimization of filler type, loading fraction, and dispersion state, Subha aims to tailor the electrical and dielectric responses of the composites, thereby maximizing shielding effectiveness without compromising mechanical performance. This integrated structure–property approach supports the development of next-generation, non-metallic EMI shielding materials suitable for modern electronic and communication systems, wearable technologies, and aerospace applications.
