About Me

I am a PhD student at Tufts University studying Computer Science and Cognitive Science.  Before coming to Tufts, I recieved a M.Eng in Electrical and Computer Engineering from National University of Singapore and a B.Sc. in Computer Engineering from Iran University of Science and Technology. Broadly speaking, my research interests lie at the intersection of AI, machine learning and cognitive science.
More specifically, I am interested in truly adaptive/data-driven NLP/AI systems. My research is informed by studying the developmental trajectory of intelligence in young infants who start with little or no knowledge of the world but manage to learn so much so fast, mainly by just adapting to the world around them. In my PhD dissertation, I work on the development of a unified incremental and memory-limited computational model of infant's word learning, integrating syntactic and social cues. More specifically, my work is concerned with computational accounts of early bootstrapping effects during language acquisition in the absence of adult-like structured representations.
