About
Reliability and qualification engineer with 7+ years of industrial experience qualifying silicon-backplane LCOS devices for automotive head-up displays to AEC-Q100 and GM standards. Executed HTOL, thermal shock, power-on thermal cycling and humidity stress qualification across EV, DV and PV builds (1,000+ parts, then a final 500-part round), with failure analysis (CSAM, CT, SEM) and 8D/CAPA on rejects. Brought the GM HUD programme to high-volume production (delivered 2025), raising yield from 60% to 95%.
Ph.D. in Physics; co-inventor on 9 patents.
Experience
Lead Engineer - Dualitas Ltd - Milton Keynes, UK
(2026-06)
- Leading technical and market benchmarking of LCOS spatial light modulators for AI applications and defining the development roadmap.
Lead Architect & LCOS Developer (Contract / Advisor) - Inmersia - Barcelona, Spain
(2026-03 - 2026-06)

Lead Materials & Display Manager (Manufacturing Readiness & Process NPI) - Envisics Ltd - Milton Keynes, UK
(2019-05 - 2026-05)
LCOS for automotive head-up display (HUD)
- Led reliability and packaging qualification of silicon-backplane LCOS devices to AEC-Q100 and GM requirements (HTOL, thermal shock, power-on thermal cycling, humidity), bringing the GM HUD programme to high-volume production (2025).
- Translated GM quality and reliability requirements into material specifications, CTQ parameters, control plans and qualification plans for multi-stage cleanroom packaging assemblies.
- Led 8D and root-cause investigations into stress failures and non-conformances (CSAM, CT, SEM); deployed CAPAs that eliminated recurring defects.
- Raised yield from 60% to 95% and cut cycle time by 30% using Lean Six Sigma and DFMA.
- Qualified 10 major sub-component suppliers, authored technical RFQs, set IQC metrics and aligned processes with the China-based OSAT partner.
- Line managed a 13-person production and engineering team, including an engineer embedded at the OSAT line.
