research overview |
<div>I am interested in the application of non-destructive high resolution imaging
and analysis techniques to rare and precious materials. By employing a range of in-situ,
non-destructive or minimally destructive methods samples can be subject to rigorous
analysis but also preserved for future study.</div><div>- Analysis of ancient materials</div><div>-
Application of FIBSEM to precious meteoritical and geological materials</div><div>-
Milling and extraction methods in the production of TEM wafers using FIBSEM</div><div>-
3D sample analysis</div><div>- In-situ analysis techniques</div><div>- Novel applications
of high resolution microscopy</div><div>- Pallasites, iron meteorites and evidence
of parent body processing</div><div>- Classification and study of newly discovered
meteorites</div><div> </div><div> </div><div><strong>A selection of conference
