Madhusudan Ghosh

Madhusudan Ghosh is a PhD student registered at the Indian Association of the Cultivation of Sciences (IACS) supervised by Sudip Naskar and Partha Basuchoudhury. His PhD topic is related to knowledge base construction from scientific articles.

Nilanjan Sinhababu

Nilanjan Sinhababu is a PhD student registered at the Indian Institute of Technology, Kharagpur supervised by Pabitra Mitra. His PhD topic explores In-Context Learning and Generative IR.

Subinay Adhikari

Subinay Adhikari is a PhD student registered at the Indian Institute of Science Education and Research (IISER) Kolkata, supervised by Kripabandhu Ghosh and Dwaipayan Roy. His PhD topic explore the applications of generative models for Legal Document Processing.

Past PhD/mentored students

Suchana Dutta

Suchana Dutta is a PhD student at University College, Dublin (UCD). Her primary supervisor from UCD is Derek Greene. With her I’m pursuing novel search interfaces and algorithms towards addressing causality driven search, i.e. where a search user wants to find out documents answering the Why question, e.g. why was Osama bin Laden assassinated? etc.

Chandan Biswas

Chandan Biswas is a PhD student of mine registered at the Indian Statistical Institute. I co-supervise his PhD along with Ujjwal Bhattacharya. Chandan’s work investigates how to develop both unsupervised and supervised learning models under privacy preservation constraints (specifically useful in a distributed computing environment in an untrusted network).

Dwaipayan Roy is an Asst. Professor in the Indian Institute Of Sscience Education and Research, Kolkata. He graduated out of the Indian Statistical Institute with his PhD degree in 2019. He was the first PhD student of mine (co-supervised by Mandar Mitra). His PhD investigated the use of embedded word representations for the purpose of improving retrieval effectiveness.

Anirban Chakraborty

Anirban Chakraborty is a postdoctoral researcher in Edinburgh University. He was a PhD student at the School of Computer Science, Trinity College Dublin. His PhD topic includes investigating information retrieval (IR) based approaches for effective points-of-interest (POI) recommendation. I menotored him during his PhD studies.

Swarup Chattopadhyay

Swarup Chattopadhay was a PhD student at the Indian Statistical Institute. With Swarup, I’m investigating faster and more effective solutions of standard graph optimization problems, such as clique, coloring, community funding etc. using embedded representations of graph nodes.

Collaborators

Here’s a list of researchers from other universities that I’m fortunate to actively collaborate with.
