Vijay Tailor-Hamblin

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, as well as an established Research Orthoptist at Moorfields Eye Hospital.

Annie completed her undergraduate degree at the University of Manchester and joined the lab for a Ph.D. rotation project through the BBSRC LIDo program in February 2019. She stayed on to examine variations in face recognition across the visual field, in collaboration with Tessa Dekker and Valérie Goffaux, and her PhD was awarded in November 2023. Her project involved both behavioural psychophysics and functional magnetic resonance imaging. She is currently a postdoctoral research fellow at the University of York.

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. 

Vilomi Bhatia

M.Sc. student

Vilomi completed MBBS and B.Sc. degrees at St. George’s University of London, and is conducting her masters project in the lab as part of the M.Sc. Cognitive Neuroscience program.

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.
