About Me
Understanding materials. Designing what matters.
I am a materials scientist with more than seven years of research experience in nanomaterials, thin-film fabrication, advanced characterisation — especially SEM — and physical metallurgy. My work combines experimental characterisation with mechanism-based analysis to understand how processing, defects and interfaces…
What I Bring Across Materials Science
Processing. Characterization. Thin films. Atomic transport. Scientific decision-making.
I bring a materials-physics perspective to engineering problems, connecting microstructure, processing, deformation, diffusion, and performance. My strength lies in understanding why materials behave the way they do, translating complex observations into…

Special Skills & Expertise
Where materials decisions are made
I use these tools not only to measure materials, but to explain what the results mean for performance, process optimisation and material selection.
Microstructure–Property Relationships
Understanding how grain structure, interfaces, defects, texture and processing history influence material behaviour and performance.
Defects, Interfaces & Transport
Analysis of grain-boundary diffusion, segregation, atomic transport and defect-controlled behaviour in metals, alloys and thin-film systems.
Deformation, Creep & Reliability
Studying how materials respond to mechanical loading, deformation processing, thermal exposure and long-term service conditions.
Thin Films & Process-Dependent Behaviour
Experience with thin-film fabrication, PVD/sputtered layers and functional films, with attention to structure, interfaces and processing effects.
Advanced Materials Characterisation
Electron microscopy, EBSD/OIM, EDX/EDS, XRD, SIMS and indentation methods to study structure, chemistry, texture, defects and local properties.
Electron Microscopy & Diffraction
SEM imaging, EBSD/OIM orientation mapping, EDS/EDX chemistry and XRD phase analysis — the day-to-day tools for reading a microstructure and what processing did to it.

Cr Diffusion in Ni Bicrystals
Atomic transport through a single grain boundary
A high-purity Ni bicrystal used as a model system to resolve how chromium moves through one defined Σ11 grain boundary — and why a single boundary is not a single…

Intrinsic Heterogeneity in UFG Ni
Hidden fast pathways in severely deformed metals
Severe plastic deformation does not produce one kind of grain boundary. It produces a hierarchy — and the fast ones dominate transport.

Metal–Metal Composites & Hierarchical Materials
Building performance through engineered interfaces
Metallic systems where different metals, interfaces and microstructural levels are deliberately combined to create stronger and more reliable materials.

Thin Films & Nanomaterials
Functional materials designed at the nanoscale
At reduced dimensions, small changes in morphology, composition or interface quality strongly influence stability, transport and functional performance.

Research Philosophy
Understand how materials change — then design how technology performs.
Science that improves technology and society begins with seeing clearly. I treat data as evidence, think across scales — from atoms to components — and push every study from description toward causality.
See clearly
Use data as evidence.
Think across scales
Atoms to components.
Explain mechanisms
Move from description to causality.
Process with purpose
Microstructure matters; properties drive function.
How I Work
Measurement discipline. Mechanistic understanding. Clear decisions.
From careful measurement to meaningful decisions.
Prepare
Careful sample preparation and planning.
Process
Deformation, deposition, annealing or testing.
Measure
Radiotracer, SIMS, SEM/EBSD, XRD, indentation.
Validate
Check artifacts, background, sectioning, reliability.
Interpret
Link to defects, boundaries, interfaces and properties.
Communicate
Scientific writing, visualization and technical impact.
