Biography

I am a Research Associate working in the Optics Group. My research interests involve applications of temporally resolved single pixel imaging for measuring very fast phenomena. Current themes within this area are the imaging of the modes of optical fibres, 3D imaging of a scene and fluorescence imaging.

Previously I studied at the University of Birmingham where I received a MSci in Theoretical Physics and went on to complete a PhD in ultra-cold atoms. I worked in industry for 5 years specialising in CMOS imaging sensors, characterising devices for use on the JUICE mission to Jupiter's moons and also for ground based astronomy.

I can be found in Room 155 in the basement of the Kelvin Building.
