Vijay Tailor

Postdoctoral research associate

After an undergraduate degree in orthoptics at the University of Liverpool and an M.Sc. 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 joined the lab for his Ph.D. research, where he examined the visual deficits associated with congenital nystagmus using behavioural psychophysics, eye tracking, and functional magnetic resonance imaging. He is currently a postdoctoral fellow in the lab, funded by the Moorfields Eye Charity to examine visual function in children with congenital nystagmus.

Jenny completed her undergraduate degree at the University of Auckland. She joined the lab to begin her Ph.D. in 2023, which examines the visual symptoms of Posterior Cortical Atrophy, a subtype of dementia that predominantly affects visual areas of the brain. Her project involves both behavioural psychophysics and functional magnetic resonance imaging.

Alexandra Kalpadakis-Smith

Ph.D. student

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 compared crowding in our peripheral vision with the elevations in crowding that arise in the central vision of children with amblyopia. Her project used both behavioural psychophysics and functional magnetic resonance imaging. She obtained her Ph.D. in 2019, and currently works for AstraZeneca. 

Fatima Ali

Ph.D. rotation 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, using behavioural psychophysics to investigate individual differences in crowding and to develop new methodologies for the rapid measurement of these effects. She is currently completing her PhD research in Jennifer Linden’s lab at the UCL Ear Institute. 

Kamilla Dombai

M.Sc. student

Kamilla conducted her masters project in the lab as part of the M.Sc. Psychological Sciences program. Her project examined crowding effects on motion and colour perception, comparing the disruptive effect on these visual dimensions in peripheral vision with the disruptions that affect foveal vision in cases of strabismic amblyopia and during normal development. 

Michael Parsons

M.Sc. 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. 

Luna Huestegge

Third-year project student

Jenna was a third year B.Sc. Psychology student, joining the lab for her final-year dissertation project. Her project examined depth perception in peripheral vision and its susceptibility to crowding effects. 

Jade Bouffard

Third-year project student

Jade was a third year B.Sc. Psychology student, joining the lab for her final-year dissertation project. Her project involved a large-scale online test of individual differences in visual imagery and their relation to our perceptual abilities. 

Srishti Agarwal

Third-year project student

Srishti was an intercalated medical student, spending a year in the lab and the Division of Psychology. Her third-year research project examined the role of configural processing individual differences in face recognition, in collaboration with Katie Fisher.

Xuan Kai Lee

Third-year project student

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.
