does basic visual information that we sample from the environment in
the form of luminance and colour contrast get transformed by our visual
system into a representation of our environment? This might
seem a trivial question, but the rich world of objects that we
experience in everyday life is derived from basic signals about
brightness and chromaticity which subsequently get
processed by structurally and functionally complex areas of our brain.
My work concerns object representation, in particular its relation to
the synergistic processing of luminance and chromatic
This might seem a trivial question, but the rich world of objects that we experience in everyday life is derived from basic signals about brightness and chromaticity which subsequently get
processed by structurally and functionally complex areas of our brain. My work concerns object representation, in particular its relation to the synergistic processing of luminance and chromaticsignals. I am interested in how this joint processing influences perceptual organisation of scenes, attentional selection and object representation.
such as depth or coherence that lead to certain percepts being formed.
On the other hand, EEG provides a window into rapidly occuring neural
processes that relate to these visual percepts.
I use a combination of psychophysical and EEG methods in my work. Psychophysics allows me to measure levels of contrast necessary to perform various visual tasks, or levels of other stimulus
Recently, I was funded by the BBSRC to investigate the early advantage of luminance for object representation and its cross-talk with chromatic pathways in human visual scene analysis.
I conducted this work together with Dr Ben Jennings between 2011 and 2013. You can find more information about this research on our project website. I was also involved in a DFG-funded projectthat investigated the neural mechanisms of visual object representation, which was conducted at the University of Leipzig by Prof Matthias M Mueller and Dr Matt Craddock.
Other ongoing external collaborations include: Matt Field, University of Liverpool (attentional bias for alcohol-related cues); Sophie Wuerger, University of Liverpool (colour-based attention),Corinna Haenschel, City University London (inputs into visual working memory) and Andreas Keil, University of Florida, Gainsville (contributions of chromatic signals to emotional conditioning).
projects for third year students. For those interested in postgraduate study, School of
Psychology has a Masters by Research programme, so please approach me if you'd like to do an MRes in my lab.
Students that are interested in colour vision, object representation or attention should get in touch. I am happy to have undergraduate students helping in the lab and to apply for funding
