Engineering Photonics member awarded Royal Academy of Engineering research fellowship

Engineering Photonics member Dr Thomas Kissinger has been awarded a prestigious fully-funded Research Fellowship by the Royal Academy of Engineering. Thomas is one of 17 engineers across the UK selected and the fellowship will provide £491,000 funding over five years, starting in November 2018.

In the project entitled “Doppler-Enhanced Lidar System Using Range-Resolved Interferometry”, Thomas will investigate a new type of interferometric 3D imaging system, originally based on work carried out during his own PhD at Engineering Photonics. This novel device can provide high-quality velocity and acceleration data in addition to 3D images and could potentially be beneficial across a wide range of applications, including manufacturing, robotics, autonomous vehicles and healthcare.

Rank Prize symposium: Grasmere 2018

In October, Jonathan Hallam and Ralph Tatam attended the Rank Prize symposium on fibre optic and photonic sensors for industrial and healthcare applications. The symposium was held at the Wordsworth Hotel in Grasmere, which is located in the beautiful Lake District National Park in Cumbria.

Jonathan presented his work on fibre-optic optical coherence tomography for high speed flow measurement applications, whilst Ralph discussed recent developments in engineering photonics for aerospace, manufacturing and healthcare.

The symposium was very much enjoyed with lots of three-course meals and a free bar that went on into the night.

Optical Fibre Sensors: Lausanne 2018

In September, Antonio Rendon-Romero, Jonathan Hallam, and Steve James travelled to Switzerland to attend the 26th International Conference on Optical Fibre Sensors. Antonio presented a poster on his work on fibre Bragg grating immunosensors and Jonathan delivered a talk on the use of single-mode optical fibres in optical coherence tomography.

FLAIR 2018: Assisi

In September, James Bremner, one of the department's PhD researchers attended the Field Laser Applications in Industry and Research (FLAIR) conference in Assisi, Italy. FLAIR is a conference that brings together researchers and industry to discuss new work in the field of molecular species detection.

Talks included work on  scales ranging from planetary environmental monitoring to biochemical processes. James presented a poster on his work on the use of Range Resolved Interferometry (RRI) to allow the measurement of methane concentrations in multiple locations simultaneously.

As well as a fascinating set of scientific talks and industry presentation, FLAIR included a chance for James to experience the beautiful Umbrian countryside and the history of Assisi, and St. Francis its most famous son.

Young Researchers' Futures meeting: Edinburgh 2018

In September, Jonathan Hallam returned to Edinburgh to attend the Royal Academy of Engineering's Young Researchers' Futures meeting. Organised by the Academy’s panel for Biomedical Engineering, this biennial, multi-disciplinary event provides a forum for the best young engineers and scientists from throughout the UK. Jonathan presented his work on high-speed microfluidic particle velocimetry using optical coherence tomography.

International Mass Spectrometry: Florence 2018

In August, Célia Lourenço travelled to Florence to attend the 22nd International Mass Spectrometry Conference. Célia presented two posters covering both her PhD research on mass spectrometry as well as her recent work investigating the volatile constituent of composite materials at elevated temperatures. The conference was held at the historic "Fortezza da Basso", a masterpiece of Renaissance military architecture, built in 1534-1537, fully restored and located downtown, a few steps away from many hotels and all the attractions (museums, theatres, monuments, etc) of the city.
