About

I am currently a post-doctoral researcher working with Prof. Gerhard Weikum, in the Databases and Information Systems Group at the Max Planck Institute for Informatics (MPII), Saarbruecken, Germany. My current research areas include question-answering over knowledge bases and text, and user-oriented privacy and transparency in online forums. In general, I am really passionate about applying language technology in and around text-based search. Prior to MPII, I worked for one and a half years as a Computer Scientist at Adobe Research, Bangalore, India. At Adobe, I worked on various text mining use cases involving the Adobe Marketing Cloud and the Adobe Document Cloud product lines. I completed my PhD as a Microsoft Research India PhD Fellow from the Indian Institute of Technology (IIT) Kharagpur, working under the supervision of Prof. Niloy Ganguly (IIT Kharagpur) and Dr. Monojit Choudhury (Microsoft Research India). During my PhD, I explored Web search query understanding, working on aspects like query segmentation, query intent discovery, and query complexity analysis. I did my masters' at IIT Roorkee (a beautiul town near Hardwar, India) and my bachelors' at Jadavpur University, Kolkata, India. I was born and brought up in the City of Joy. When not working, I can often be found poring over all kinds of word and logic puzzles.
