News: Starting October 2012, I have joined Apple Inc. in Cupertino, CA as a Frameworks Engineer in the Natural Language Processing Group. I will not be maintaining this academic website anymore. For the latest, please refer to my LinkedIn profile.

Currently: Frameworks Engineer - Natural Languages, Apple Inc.

Previously: Ph.D. Student in Machine Learning and Natural Language Processing
Department of Electrical and Computer Engineering, Cockrell School of Engineering
The University of Texas at Austin

I am primarily interested in artificial intelligence. More specifically, statistical machine learning (graphical models, Bayesian data analysis, cluster analysis, structured prediction), natural language processing (syntactic and semantic parsing, WSD, NER), data mining, information retrieval and search, and applied optimization.

My past research dealt with scalability issues in machine translation based and kernel based approaches to semantic parsing under the supervison of Professor Raymond Mooney in the Machine Learning Research Group, which is a part of the Artificial Intelligence Laboratory.

I also spent a semester working with Professor Russell Poldrack on Latent Dirichlet Allocation (LDA) and its application to text as well as voxel data obtained from f-MRI literature/experiments.

During my undergraduate years, I had the opportunity to gain valuable research experience at the Indian Statistical Institute Calcutta (working on pixel clustering for image segmentation problems in CAT scan images of the brain with an Indian National Academy of Engineering Fellowship), National Institute of Technology Surat, Indian Institute of Technology Bombay and Indian Institute of Technology Kharagpur.
