About me


I received my B.Sc. and M.Sc. degrees in colour science and technology from Amirkabir University, Tehran, Iran. It doesn’t probably sound surprising coming from a PhD student who works on color vision, but color vision has been my passion since I realised in my studies of colour science that there can be a considerable difference between the physical characteristics of materials and our perception of material properties. I got the opportunity to empirically investigate the “Crispening effect” and effects of simultaneous contrasts within my M.Sc projects . These studies were aimed at evaluating mathematical models of colour appearance. For this, I measured subjective colour appearance in psychophysical experiments and compared the data of the participants with the predictions made by the different mathematical models.
Currently, I am a PhD student supervised by Dr. Christoph Witzel at the university of Southampton evaluating the performance of a kind of transformation mapping illuminant LMS signals to reflected LMS signals.

At the moment, my research interests fall in these categories:
1) Colour categorization and colour specification
2) Colour constancy
3) hue for 3D objects,
4) higher order of color vision mechanisms.
