Supervision

Proud to supervise/mentor a number of PhD students, each possessing an inquisitive mind seeking to find solutions to challenging research questions. A number of my recent research papers features these bright young minds as my co-authors.

Current PhD students at the University of Glasgow

Akis Lionis

Akis Lionis is my current PhD student at the University of Glasgow. He graduated with MSc in Artificial Intelligence from the University of Amsterdam. His PhD topic centres around effective parametric approaches for agentic RAG.

Hamish Clark

Hanish Clark is my current PhD student at the University of Glasgow. Hamish’s PhD topic involves proactive information seeking for humans and LLM generators.

Xuejun Chang

Xuejun Chang is my current PhD student at the University of Glasgow. Xuejun’s PhD topic involves mitigating document exposure biases in neural models.

Andrew Parry

Andrew Parry is my current PhD student at the University of Glasgow. Andrew’s PhD topic involves investigation of adversarial learning for neural models.

Manish Chandra

Manish Chandra is my current student who’s doing a PhD (part-time) at the University of Glasgow. Manish’s PhD topic involves investigation of explanation methodologies and their quantitative evaluation. He completed his post-graduation from IIT-KGP in 2021.

Fangzheng (Daneil) Tian

Fangzheng (Daniel) Tian is my current PhD student at the University of Glasgow. Daniel’s PhD topic involves estimating the performance of retrieval-augmented generation (RAG) systems.

Current PhD student mentees external to the University of Glasgow

Payel Santra

Payel Santra is a PhD student registered at the Indian Association of the Cultivation of Sciences (IACS) supervised by Partha Basuchoudhury. Her PhD topic is related to misinformation mitigation with large language models (LLMs).

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.

Past PhD/mentored students

Madhusudan Ghosh

Madhusudan Ghosh completed his PhD from the Indian Association of the Cultivation of Sciences (IACS) supervised by Sudip Naskar and Partha Basuchoudhury. His PhD topic was related to knowledge base construction from scientific articles. He is now working in Phillips Research, India.

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
