Committee role:Ordinary Member
Job title:Career Development Lecturer
Workplace:University of Oxford Department of Experimental Psychology
Institution:University of Oxford

Laura Young completed her MPhys and PhD at Durham University. Her doctoral work was based in the Centre for Advanced Instrumentation but in collaboration with the Psychology Department. This research examined the impact of optical aberrations in the human eye on visual performance. Since completing her PhD in 2012, Laura has worked between the fields of optical physics, microscopy and human visual perception. 

In 2017 she was appointed the first Career Development Lecturer in the Department of Experimental Psychology at the University of Oxford where she collaborates with physicists, engineers, psychologists and ophthalmologists.

Her interests are in using optical imaging techniques to address research questions in vision; from the optical development of the eye to the study of visual function. In collaboration with Durham University she has developed an adaptive optics scanning laser ophthalmoscope for imaging the human retina in vivo with cellular resolution. This instrument is providing insights into the mechanisms underlying normal visual perception and into the time-course of inherited retinal disease in the clinical population.
