Compositionality can be found almost everywhere onelooks. It is manifest in as diverse a range of entities as objects around us,the languages we use, and even our actions and interactions with the world. Mywork involves exploring and exploiting the general nature of suchcompositionality, often across multiple modalities, to solve deep and complexproblems in perception.

I demonstrate such ability in a variety of domainsincluding part-based structures, board games, and activity recognition. I also showevidence for a particular kind of compositionality in how the brain perceivesthe world, lending further credence to the ubiquity and utility of compositionality.
