I am an independent researcher, my primary research interest is focused on the Structural Analysis of Indus signs, I have been able to decipher the Indus Script as an alphabet representing Sindhu Prakrit; the language of the Indus script. My research justifies each sign and classifies vowels, diphthongs, consonants, double consonants, aspirates, combined consonants and ligatures. It identifies the uniform procedure of diacritical marks, diphthongs, dual consonants, and aspirates in the alphabet.
