He was a member of the central council of the International Brain Research Organization at UNESCO, participated in many professional societies, developed and taught many courses in color science, psychophysiology, psychophysics, and quantitative methodology.

Chingis Izmailov's main achievements are in the field of color science, but he also contributed to other areas of psychophysiology and psychophysics, such as multidimensional scaling of geometric shapes and emotions in facial expressions.

His experimental work and mathematical models were primarily based on various forms of multidimensional scaling,[1][2][3][4][5][6][7][8] and on amplitudes of evoked potentials in humans[9] and electroretinogram in frogs[10][11] in response to an abrupt change of one stimulus to another.

In particular, the model provides a way of quantifying a spectrum of color abnormalities from the very mild anomalous variations to severe deficiencies, like protanopia and deuteranopia.

[11] In the later period of his life Chingis Izmailov was working on a comprehensive theory of perception as having a formal structure of a language, with levels analogous to those of graphemes/phonemes, letters, and words.
