About

Rishiraj Saha Roy is a Senior Researcher at the Max Planck Institute for Informatics (MPII), Saarbruecken, Germany, leading the research group on Question Answering, that focuses on robust and interpretable solutions for answering natural language questions over structured and unstructured data. He belongs to the Databases and Information Systems Department, that is headed by MPII director Prof. Gerhard Weikum. His current research focus is on question-answering over structured and unstructured sources of knowledge. In general, he is really passionate about applying language technology in and around text-based search. Prior to joining MPII, he worked for one and a half years as a Computer Scientist at Adobe Research, Bangalore, India. At Adobe, he worked on various text mining use cases involving the Adobe Marketing Cloud and the Adobe Document Cloud product lines. He completed his 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 his PhD, he explored Web search query understanding, working on aspects like query segmentation, query intent discovery, and query complexity analysis. He did his masters' at IIT Roorkee (a beautiul town near Hardwar, India) and his bachelors' at Jadavpur University, Kolkata, India. He was born and brought up in the City of Joy. When not working, he can often be found poring over all kinds of word and logic puzzles.
