Arnab received his Ph.D. in Computer Science from the University of Michigan where he was awarded the Yahoo! Research PhD Fellowship. At Michigan, he was part of the Database Research Group and was advised by H. V. Jagadish. His thesis addressed the problem of making search in databases easier, as part of the group’s broader goal of making databases usable. During internships at Yahoo! Research, Google and Microsoft Research, Arnab worked on various large-scale systems, dealing with problems in web and social search, data integration and data cubing.
During his PhD, Arnab was involved with the Michigan CSE Graduate Society board in various capacities including Secretary, Treasurer and President.
Before graduate school, he worked with Prof. Soumen Chakrabarti and Prof. S. Sudarshan at IIT Bombay. Arnab was part of the BANKS and SPIN projects, where he worked on various aspects of ranking graph-based data.
During his undergraduate years at the University of Delhi, Arnab teamed up with 2 of his college-mates to start idya Research, where he developed novel web-based applications.
He has also had the opportunity of interning with Media Lab Asia, and the technical research group at Yahoo! Bangalore. He worked with the Question Answering group at Google in the summer of 2007, the Database Group at Microsoft Research in the summer of 2008, the Web Information Management Group at Yahoo! Research in the summer of 2009 and the Search Labs group at Microsoft Research Silicon Valley in the summer of 2011.
Apart from research, he has also been a contributor to Drupal, the framework that runs this website. Arnab created the Captcha and Similar Entries modules, which are now maintained by other members of the Drupal community. He also wrote BaconSnake, parts of which eventually made its way into Apache Pig 0.8’s Jython UDF feature.
