Dr. Jenny Bosten
Jenny Bosten's undergraduate degree from the University of Cambridge is in Natural Sciences with a specialism in neuroscience. She stayed at Cambridge to complete her doctoral training with Professor John Mollon at the Department of Experimental Psychology, and then became a Research Fellow in Neuroscience at Gonville and Caius College, Cambridge (2008-2010 and 2012-2014). She was a post-doctoral researcher at UC San Diego in the lab of Professor Donald MacLeod (2010-2012). She joined the University of Sussex as Lecturer in 2015, and became a Senior Lecturer in 2018.
Ana Rozman
Ana has joined the Vision Lab in 2023 as a Postdoctoral Researcher. She is interested in how the brain processes colour signals to build colour representations, and how neuroimaging and psychophysical methods can be used to study these mechanisms. She completed her PhD titled Neural Mechanisms of Saturation at the University of Aberdeen under supervision of Dr Jasna Martinovic. Prior to studying human colour vision, Ana has obtained a BA(Hons) in Film and Media with Psychology from the University of Stirling.
Simon Saryazdi
Simon is interested in understanding the phenomenology of visual perception conditions and the roots of individual differences in visual experience. His main research interests surround visual snow syndrome and hallucinogen persisting perception disorder, two closely related visual perception conditions. He applies a range of methodological and statistical approaches to his research to understand differences at both the group and individual level.
Ian Pennock
Ian joined the the Vision Lab and Sussex Colour Group in 2019 as a Doctoral Researcher, and has continued at the Sussex Vision Lab as a postdoctoral research associate since 2023. Previous, Ian completed a double MSc degree in Cognitive Neuroscience and AI from the University of Osnabrueck, Germany and the University of Trento, Italy. He is interested in using fMRI to understand cortical colour processing, including multivariate and univariate methods and encoding models. His PhD research uncovered the ventral food stream, a stream in the ventral visual cortex that is colour-biased and food-selective. Currently he uses encoding models to understand colour processing in the early cortex, and is conducting new fMRI studies to investigate the interaction between colour and food representations in the ventral food stream.
Lemona Xinxuan Zhang
Lemona completed her undergraduate degree in Psychological and Behavioural Sciences at Homerton College, University of Cambridge. After finishing an MRes degree in Cognitive Neuroscience at UCL, she started her PhD at the vision lab in 2022, jointly funded by the ERC COLOURCODE grant and the Sussex School of Psychology. She is also collaborating with the Sussex Centre for Consciousness Science. She is interested in the subjective experience of perceiving colours (real and hallucinatory), and its neural basis. She uses a range of research techniques, including stroboscopic stimulation, EEG/MEG, and potentially TMS.
Lucy Somers
Lucy completed her PhD at the Sussex Vision Lab in 2022. Her thesis presented her work modelling the effect of EnChroma filters on the colour vision of anomalous trichromats, and providing empirical tests of their effectiveness. It also presented her work on modelling and testing the effectiveness of the Ishihara Plates Test for detecting mild anomalous trichromacy. During her PhD she also used steady-state visually evoked potentials to measure postercfeptoral compensation in anomalous trichromats. Post-PhD Lucy has worked with Sophie Foster investigating the effect of mental imagery on SSVEPs. She is now back in the Vision Lab using SSVEPs to investigate cortical colour processing. Lucy is also an artist and currently pursues art projects that combine her interests in art, lighting and vision science.
