Professor Rajesh Rao have done extensive research to decipher Indus Script. His research paper was published in IEEE with subject "Probabilistic methods for analyzing sequences are providing new insights into the 4,000-year-old undeciphered script of the Indus civilization". He also rebutted claims of Steve Farmer, Richard Sproat, and Michael Witzel that "the Indus valley civilization was illiterate and that Indus writing was a collection of political or religious symbols". His paper to debunk above thesis from Witzel can be read here . Following is his excellent talk on the research at TED.
