Oma esittely

I am a materials scientist and mechanical engineer with six years if research experience, specializing in the micromechanics, processing and characterization of advanced structural materials. My research focuses on understanding how microstructure, interfaces and processing influence deformation and failure across multiple length scales, particularly under extreme conditions. I combine advanced micromechanical testing, electron microscopy, materials processing and computational approaches to develop materials with improved strength, durability and thermal stability.

I completed my Masters and PhD from IIT Madras in Chennai, India. In my free time, I love to be in nature, cooking and listening to music.

Työtehtävät

At Tampere University, I conduct research on the mechanical behaviour of advanced materials, with particular emphasis on high-strain rate and high-temperature behavior for material to be qualified for extreme applications. My responsibilities include experimental design, micro- and nanomechanical testing, microstructural characterization, scientific publishing, development of research proposals and collaboration with multidisciplinary research teams. I also contribute to mentoring students and developing new experimental approaches for studying materials at small length scales.

Tutkimustavoitteet

My long-term research goal is to develop a mechanistic understanding of how microstructure, interfaces and defects control material behaviour under extreme conditions, and to translate this understanding into the design of more durable, lightweight and resource-efficient structural materials.

A particular objective is to bridge the gap between nanoscale deformation mechanisms and engineering-scale material performance by combining high-resolution experiments, advanced characterization, physics-based materials design and data-driven approaches. Ultimately, I aim to establish integrated processing-structure-property-performance relationships that enable the design of next-generation materials for demanding energy, transportation and high-temperature applications.
