After completing a postdoctoral fellowship with Brian Wandell at Stanford, I joined SKERI to set up the Brain Imaging Center in 2002.

Current research projects include the combined use of fMRI, EEG and MEG to study mid-level vision in humans and an investigation into the representation of color signals in human visual cortex.

We use the Stanford VISTA toolbox for fMRI data analysis and help to maintain and update this software package. In addition, I have developed some tools that may be useful to other researchers. These include scripts to control the Arrington eyetracker from matlab and some functions for importing EEG and MEG data into the VISTA toolbox. These tools are available here.

I run an online color blindness simulator called 'Vischeck' here. I have also developed an algorithm that corrects images for color blind observers.
