I am a PhD candidate in Computer Science at the Machine Learning Research Group of the University of Texas, Austin. My interests lie at the intersection of Machine Learning and Natural Language Processing. I work with my advisor Prof. Ray Mooney on ensembling machine learning models for natural language and vision. We are currently exploring the use of "explanation" to improve stacked ensembling with applications to text and images. My proposal here has more details.
I completed my MS thesis with Jason Baldridge on new topic detection using topical alignment from tweets based on their author and recipient. In the past I have also worked with Maytal Saar-Tsechansky on rumour detection using tweets and with Inderjit Dhillon on analysis of time series tweets as well as fast parallel graph mining.
