EXPLORING ENERGY STORAGE MATERIALS/ SYSTEMS -
LINKING PARTICLES TO SYSTEM BEHAVIOR

Imaging • Experimental Characterization • Multi-scale Modeling


Hi, I’m Aastha. I spend a lot of time looking inside materials and even more time trying to make sense of what I see.

Currently based in the Netherlands, my research journey has been shaped by a curiosity to understand how microscopic changes in materials influence macroscopic system behavior. I am a Researcher in chemical engineering domain specializing in thermal/material characterization, X-ray micro-CT, multiscale imaging and data-driven CFD modeling. I develop small scale experiment set-ups, validated CFD models that link 3D microstructure to various transport phenomena, and performance across complex materials and reactor systems.

My experience covers microstructure quantification, porous media behavior, reaction kinetics, and multiphysics simulation. I have also worked on composite energy storage material manufacturing and on extracting kinetic models from thermogravimetric data for predictive applications.
