I am a materials scientist working to understand how materials behave under extreme environments such as nuclear irradiation, high strain rates, and high temperatures. I am currently a Postdoctoral Research Scholar at Iowa State University. I completed my Ph.D. at IIT Bombay, where I worked on the precipitation and deformation behaviour of maraging steels subjected to different levels of strain.
My research centers on the quantitative, multiscale mechanical characterization of materials in extreme environments, combining mechanical testing with advanced microscopy to connect deformation mechanisms from individual grains to industrially relevant length scales.
The discovery involved in solving problems of real consequence to the world, and the opportunity to mentor the next generation of researchers and pass that knowledge forward, are what keep me motivated on this journey.

From µm to mm, I bridge the micro, meso, and macro length scales to understand how a material’s microscopic structure dictates its overall performance. High-throughput nanoindentation makes it possible to map mechanical behaviour rapidly across many orientations and phases, and to test materials available only in tiny volumes (from neutron-irradiated samples too hazardous to handle in bulk, to rare fossilised and meteoritic specimens).

From single atoms to bulk grain structure, I use correlative microscopy to resolve a material’s structure across scales using atom probe tomography for precipitate composition and morphology, transmission electron microscopy for lattice and interface analysis, and SEM and EBSD for microstructure and phase distribution. Combining them on the same material links chemistry and structure directly to mechanical behaviour.

In-situ SEM micropillar compression of tantalum (BCC) in two crystallographic orientations. The orientation of the loading axis relative to the available slip systems changes how the pillar deforms: multiple, equally active slip planes in the ⟨111⟩ orientation, versus single-slip deformation in the ⟨113⟩ orientation.
