Research Engineer

I am a Research Engineer at Facebook AI Research. Previously, I completed my PhD at the University of Texas at Austin, where I studied applications of word embeddings in areas including textual entailment, lexical entailment, lexical relations, paraphrasing, and non-textual modalities. I was also briefly a visiting student at The University of Stuttgart, and completed my undergraduate studies at North Carolina State University.

Interests

Natural language processing, semantics, word embeddings, deep learning, and lexical entailment.
