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 also 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.
At Columbia, I worked on the text2scene project.For two summers (in 2012 and 2013) I interned at 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 grounded in semantic primitives.
I am interested in the relation between syntactic realization and semantic structure, as well as in the interpretation of semantic structure in context of 3D scenes and linguistic discourse.
The aim of my research is to develop joint models that integrate these different levels of representation (syntax, semantics, graphics).
One application of this work is text-to-3D-scene-generation.
More generally, I am interested in computational and lexical semantics, syntactic and semantic analysis in context, 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.
TeachingSpring 2012: COMS W3101-3 - Programming Languages: Python.
Fall 2011: TA for COMS W4705 - Introduction to Natural Language Processing (taught by Michael Collins).
NewsOn Mar 11 2013 I passed my PhD Candidacy Exam on Semantic Parsing.
I organize the NLP seminar series ( NLP meetings) at Columbia. Subscribe to the mailing list or contact me if you would like to present.In my spare time I enjoy cooking, playing my guitar, discovering New York City, hiking, traveling and taking photos.
I enjoy the company of the following other Columbia CS grad students (this is obviously an attempt to increase our Google rank, but I really do enjoy their company): Arthi Ramachandran, Apoorv Agarwal, Bob Coyne, Vinod Prabhakaran
