Manisha Tripathy, PhD
Order is invisible. Failure is not. I work on the space between.
I study how interfaces, surfaces and microstructures change under extreme mechanical and thermal conditions, with electron microscopy and atom probe tomography. Before this: a PhD on how additively manufactured superalloys wear at temperature, and industry years measuring surfaces for people with real hardware on the line.
From atomic structure to materials behavior
Interfaces & Deformation
Grain boundaries and twin boundaries moving in copper at cryogenic temperature, watched live with in-situ TKD and nanomechanical testing.

Ordering & Nanoscale Chemistry
Short-range order in brass and CrCoNi alloys: how atoms pick their neighbours, measured with atom probe and 4D-STEM on the same specimen.

Structure–Property Relationships
Wear and indentation of additively manufactured superalloys at temperature: how the printed microstructure decides how the surface hardens, cracks and wears.

Advanced Characterization
Methods that put atom probe, electron microscopy and in-situ testing on one sample, so each technique checks the others.
Learn more →A multi-technique perspective
No single instrument tells the whole story. I combine techniques that see different things, from single atoms to whole components, and trust the result where they agree.
