Congratulations to Liam Trimby, who has passed his viva. He was supervised by Prof. C. David Wright and Dr. Anna Baldycheva.Liam’s thesis was titled ‘Phase-Change Meta-Devices for Tuneable Bandpass Filtering in the Infrared’. The examiners were Prof. Martin Cryan from University of Bristol and the internal examiner was Dr. Mustafa Aziz.
His achievements include winning the poster prize at CHAMP/WAFT conference in May 2018 for his poster on Multispectral Imaging using Phase-Change Meta-Filters.
Liam has also been heavily involved in outreach, having been a Metabuddies Lead Tutor (a schools outreach scheme run by CDT students) and a tutor for Brilliant Club KS4 (an outreach scheme targeted at disadvantaged Key Stage 4 students), as well as volunteering at WOMAD in 2017 and Pint of Science in 2019
