I am a PhD student at the Institute for Natural Language Processing (IfNLP), University of Stuttgart, Germany. I work with Alex Fraser and Helmut Schmid.

I am also working as a text analysis consultant for PolyVista. We are currently working on extracting actionable information from unstructured data.

During my internship at Microsoft research, I worked with Patrick Pantel and Bill Dolan on dialogue based question answering system.

I am graduating in Nov 2012. I am looking for “JOB”. Here is my curriculum vitae.

You can find my publications below.


Research Interests:


My research interests are in: Statistical machine translation and transliteration, semi-supervised and unsupervised transliteration mining and POS tagging. After my internship at Microsoft Research, my interests evolved towards the analysis of unstructured data to extract actionable information. My current work on text analysis is focused on twitter data.

Currently, I am working on developing a standard model for unsupervised, semi-supervised and supervised transliteration mining. During my internship at Microsoft research, I worked on interactive dialogue based question answering. The interesting part of the problem was to generate questions from the information grounded in the description of objects. We do not use any knowledge based system.

Previously, I worked on Hindi-to-Urdu machine translation system which presents a novel approach to integrate transliteration to machine translation.


Current Activities:



Statistical Machine Translation reading group

I gave a talk on “Separating Transliterations from Translations in Transliteration Mining Context” at School of Science and Engineering of LUMS and PUCIT (April 2012)

I was a reviewer for the 50th Annual Meeting of the Association for Computational Linguistics

Internship at Microsoft Research Redmond (27th June - 16th September, 2011)

Statistical Learning and Language Models

Participated at the Fifth MTMarathon, Le Mans, France (Minimum Risk Decoding in Cdec with Adam Lopez)
