Profile

Biography

I studied Psychology at York University, UK, and then took research jobs at BT labs and St Andrews University. My PhD (at Aston University) investigated edge processing in human vision. I then had postdoc research positions at UCL, McGill University, Bradford University, UCL again, City University London, and UCL (yet again). In 2014 I was awarded the AVA David Marr Medal. I joined the Essex University Psychology Department as a lecturer in 2016.

Research and professional activities

Research interests

My work investigates the processing performed by the human visual system. My research mainly falls into the following areas: perceptual encoding, edge processing, visual grouping, visual attention, and coding efficiency. I also work on face perception and memory.
