John joined the department of Experimental Psychology at UCL in 2013. Prior to this he completed his Ph.D. at the Australian National University with Mark Edwards, and postdoctoral research fellowships at the UCL Institute of Ophthalmology with Steven Dakin and Peter Bex from 2008-2010, and at the Laboratoire Psychologie de la Perception of the Université Paris Descartes with Patrick Cavanagh from 2011-2013.

Alexandra completed her undergraduate degree at Royal Holloway, and first joined the eccentric vision lab for her M.Res. in Cognitive Neuroscience, for which she investigated the interaction between crowding and face recognition. She began her Ph.D. in 2015, which is comparing crowding in our peripheral vision with the elevations in crowding that arise in the central vision of children with amblyopia. Her project uses both behavioural psychophysics and functional magnetic resonance imaging.

Third-year project student

Xuan Kai Lee

Third-year project student

Michael completed his undergraduate studies at the University of Essex and joined the lab to conduct research towards his M.Sc. in Cognitive Neuroscience. His project examined the effects of crowding on motion and colour and whether they can be attributed to the same underlying mechanisms.

Yishi conducted a research project in the third year of her B.Sc. Psychology, co-supervised with Sam Solomon, as well as follow-on research over the following summer. Her work examined the perception of position, and whether position can be considered in the same light as other visual features like motion, using adaptation as a tool.

Kai conducted a research project in the third year of his B.Sc. Psychology, also co-supervised with Sam Solomon. His project examined position perception and considered whether these judgements can be considered in the same way as visual features like motion, with specific reference to distortions in perceived position that arise when performing certain judgements.

Kate Earnshaw

Third-year project student

Kate conducted a research project as an intercalated medical student, spending a year in the Division of Psychology on a project co-supervised with Sam Solomon. Her project examined motion-induced illusions of position perception and whether we can account for these effects using a population coding approach.

Joseph Danter

Third-year project student

Joe conducted a research project in the third year of his B.Sc. Psychology degree. His project examined the perceptual outcomes of crowding across the visual field, and whether this is modulated by individual differences in the size and shape of the visual field.

Rhiannon Finnie

Third-year project student

Rhiannon conducted a research project as an intercalated medical student, spending a year in the Division of Psychology. Her research project examined the perceptual outcomes of crowding and their relationship with known properties of retinotopic coding within the visual system.

Jemma joined the lab in the first year of her B.Sc. Psychology degree to assist in experiments on visual crowding. She recently received a Bradshaw-Eagle Summer Research Scholarship from the Applied Vision Association to conduct research into face recognition and our perception of position. After completing this over the summer, she is currently conducting her third-year project in the lab to continue with this work.

Jemma Davoudian

Third-year project student

Fatima joined the lab in the first year of her Ph.D. in the UCL SenSyt program. She conducted the second of her two 6-month rotations with us in the eccentric vision lab. Her project used behavioural psychophysics to investigate individual differences in crowding, with the aim to develop new methodologies for the rapid measurement of the interference that occurs in peripheral vision. She is currently completing her PhD research in Jennifer Linden’s lab at the UCL Ear Institute.

Fatima Ali

Ph.D. rotation student

After an undergraduate degree in orthoptics at the University of Liverpool and an MSc. in Clinical Ophthalmology at UCL, Vijay worked for several years as a research orthoptist at Moorfields Eye Hospital, with a focus on childhood amblyopia that has already produced several publications to date. Vijay began his PhD in September 2016 to examine the visual deficits associated with congenital nystagmus using behavioural psychophysics, eye tracking, and functional magnetic resonance imaging.
