Current research: vision



I study aspects of visual learning and generalization involving complex structured objects. My work focuses on visual categories exhibiting  high degrees of internal variation within abstract  structural constraints. Unlike other well-studied object types (e.g. faces), complex structured objects (e.g. houses) are not well-captured by template-based recognition models, which assume a rigid set of elementary  subparts. We use Bayesian inference on grammar-based representations to explain the rapid and subconscious knowledge acquisition  concerning these objects in the visual domain.

Bio sketch


I was born in Sofia, Bulgaria, in 1976. I arrived to the United States in 1995  to begin my undergraduate studies at Harvard in Linguistics. I went on to earn a doctorate in Cognitive Science from the Johns Hopkins University. I have worked and published in linguistics (minimalism, optimality theory, formal language theory), psycholinguistics,  natural language processing, and philosophy of AI. I am currently developing and applying Bayesian models to the acquisition of rich structural representations in vision and language.

Current research: language

I study the role of syntactic optionality in language, particularly as it relates to word-order variation. Previous research has shown that non-canonical word order increases  processing time, due to added structural  complexity. In that case, why is non-canonical word order used at all? We hypothesize that non-canonical word order exists because it realizes discourse linearization preferences. For example, it is advantageous from a discourse point of view to introduce established discourse entities before novel ones. If the canonical word order does not allow for this possibility, the non-canonical word order is expected, and processed easily by the recipient.
