Presently I am an Associate Professor in the Department of Computer Science and Engineering, Indian Institute of Technology, Kharagpur. Prior to this, I was working as a post doctoral researcher in the Complex Systems Lagrange Lab, ISI Foundation, Italy. I received my PhD from the Department of Computer Science and Engineering, Indian Institute of Technology, Kharagpur with a thesis on self-organization of human speech sound inventories. My main research interests center around applying complex system approaches (mainly complex networks and agent-based simulations) to different problems in (a) human language evolution and change, (b) web social media, (c) information retrieval and (d) natural language processing.
Note to aspiring applicants:
- For Post-Doc: The Institute now has a regularized procedure to appoint post-docs. Interested candidates may directly write to me with a copy of their recent resume and one letter of recommendation. The formal process for application is outlined here. You can apply here.
- For PhD: The Institute has a centralized policy for PhD entrance. You can apply here. The syllabus for the entrance test is here.
- For MS: For MS you have to first get through some project. For project advertisements from CNeRG see here. Once you are already a project staff you can apply for MS here. The syllabus for the entrance test is here. However, these days I am reluctant of taking MS students since I am more interested in longer commitments, e.g., sponsored/direct PhDs.
- For internships: We only offer summer internships; therefore, do not apply for internships in fall. In general, your internship requests directly to my mail-box will never be acknowledged! Therefore, rather apply online.
