Major achievements:
- Development on an automation system combining an industrial robot with a CNC polishing machine. The scope of this project is to deliver a fully-automated, integrated system to enhance industrial mass ultra-precision manufacture.
- Developed a process-chain for the manufacture of the mirror segments for the European Extremely Large Telescope (E-ELT) using the 'Precessions' polishing technique.
- Completed CAD and FEA of a light-weighted 1m-class Zerodur mirror and its support system design
- CNC-polished several parts up to 0.5 meter diameter, spherical, aspheric and flat, in Zerodur, BK7, ZnS, fused silica.
- Analogue electronics design and implementation for a Biased Charge Collector
Fingerprint Fingerprint is based on mining the text of the person's scientific documents to create an index of weighted terms, which defines the key subjects of each individual researcher.
