I’m interested in computational optics – enhancing optical systems such as microscopes, cameras or projectors with computer code.
My interest began with my PhD at Durham University, where I used computer modelling of the way light propagates to design digital holograms.
The holograms were printed out and projected a 3D pattern of circuitry when illuminated with a laser. We used these projected patterns to expose photoresist for the manufacture of volumetric integrated circuits and 3D antennas.
I spent a year living in the Lake District (where I grew up) after my PhD. I got to indulge my passion for outdoor sports – rock climbing, fell running and triathlon – whilst I was there, so when I decided to return to academia 91Ö±²¥ was a natural choice, being a very outdoors city with excellent Universities.
I moved to 91Ö±²¥ to work with Professor John Rodenburg FRS, and was lucky enough to join him in the pioneering days of a computational optics technique called ptychography (pronounced tie-cog- ra-fee).
Ptychography uses diffraction pattern measurements to enhance microscopes. It realises ‘perfect’ imaging, where the image of a microscopic specimen it recreates is an exact copy of how that specimen interacts with a beam of light.
I left 91Ö±²¥ University for a brief spell to work with a spin-out company on commercialisation of ptychography-enhanced microscopes. I missed the freedom of the academic environment, and returned as a Lecturer after a couple of years.
As well as my continuing research in computational optics, I now teach Digital Signal Processing (DSP) to our third years.
