This paper uses insights from Information Theory to investigate how the grammatical properties of a language affect information processing.
Petar, who has made significant contributions to an Information Theoretic approach to language (Milin et al 2009, see link below), worked with PGR Melody Dye to design a method that compares the efficiency of languages that mark nouns for gender, such as German, and languages like English that do not do this.
The paper was awarded the Marr Prize at the 2017 Cognitive Science Society conference. The Marr Prize, named in honor of the late David Marr, is given to the best paper with a student as first author.
Petar’s 2009 paper shows how relative entropy can be used to capture the effects that morphological complexity has on processing:

If you are new to the area, Petar’s accessible introduction to Information Theory and morphological processing is a great place to start:
