I work on content relevance algorithms at the intersection of information extraction and retrieval, document classification and machine learning. At Linkedin, I am currently working on building algorithms to detect spam across Linkedin.

Data Scientist @ * Currently working on content relevance algorithms (spam) * Developed machine learning models for detecting fraud & abuse across LinkedIn ecosystem From January 2014 to Present (2 years) Data Scientist @ I worked on prototyping machine learning solutions for mining text chats and web logs to drive intuitive consumer experience. I have worked on variety of ML projects: * Predicting stages of text chats (using sequence based classiers) * Algorithm to predict potential sale converts in text chats for retargeting campaigns * Developed a Python module that makes dealing with CSVs easier. * A framework for handling text chats in Python From October 2011 to January 2014 (2 years 4 months) Bengaluru Area, IndiaFull-time Research Student @ I was an MS-by-Research student at Search and Information Extraction Lab, IIIT Hyderabad. My work here focused on query categorization for Web Search. From August 2008 to August 2011 (3 years 1 month) Hyderabad Area, IndiaFull-time Research Intern @ In this internship, I worked on an Information Extraction project. The aim of the work was extraction of US postal addresses from web pages and segmenting them using CRFs. Proposed and designed an N-Gram based address extractor that extracts US addresses from a given web page. From August 2010 to February 2011 (7 months) Bengaluru Area, IndiaFull-time Research Assistant @ Worked on Enterprise Search project. My task in the project was to build document classifier for Enterprise documents. From December 2008 to August 2010 (1 year 9 months)
