Currently, I am a Computer Science PhD Candidate at Columbia University in the City of New York where I am affiliated with the Natural Language Processing Group and the Center for Computational Learning Systems (CCLS). My PhD advisor is Owen Rambow.
I am a co-founder of WordsEye, a startup company that takes text-to-scene generation, the automatic genertion of 3D scenes from natural language descriptions, to the social media market.USC/ISI working on semantics-based machine translation.
My current research is on semantic parsing of natural language into frame-based representations that can be decomposed into semantic primitives and grounded in context.
I am interested in the relation between syntactic realization and semantic structure, as well as in the interpretation of semantic structure in context of linguistic discourse and a representation of the world. The aim of my research is to develop joint models that integrate these different levels of representation (syntax, semantics, knowledge representation). One application of this work is text-to-3D-scene-generation.
More generally, I am interested in computational and lexical semantics, syntactic and semantic parsing and generation, the syntax/semantics interface, and formal languages.
I am one of the authors of the Bolinas toolkit for Synchronous Hyperedge Replacement Grammars, one of my favorite grammar formalisms.
My master's thesis was on statistical sentence generation with tree adjoining grammars.
