Natural Language Processing
I am enrolled at GSLT as a PhD student since September 16th, 2010. My interests are in computational historical linguistics, creation of language resources, and unsupervised methods in NLP. I am also affiliated with Centre for Language Technology in Göteborg.
I was a research assistant in Digital Areal Linguistics project from 2010 till 2014.
I am writing my thesis and am very much interested in taking up a research position by September 2015. I am broadly interested in language evolution and collecting comparative data for larger families and applying computationally intensive methods for modeling language change and investigating questions about language prehistory and contact in South Asia.
I contribute code to the Quantitative historical linguistics project. Clone it here.

I worked on cognate identification and phylogeny for my Masters' thesis.
The contributions of this thesis are as follows:
I spent the spring of 2012 at Max Planck Institute for Evolutionary Anthropology, Leipzig.
I spent two months (March and April of 2013) as a Guest Researcher at Alpha-Informatica
There is an interesting open-source NLP toolkit for South Asian Languages Sanchay
