About Me

I am a Postdoctoral Research Fellow at Insight Centre for Data Analytics in University College Dublin, Ireland, where I am working with the Victeur team as part of the UCD Centre for Cultural Analytics. While my current research project, Victeur (an ERC-funded project), focuses on developing computational methods to explore the role of European Migrants in Victorian and Neo-Victorian Culture, my research interest broardly includes adhoc information retrieval (IR), query performance predictions (QPP), cultural analytics and explainability. Before joining as a Postdoc, I graduated with a PhD in Computer Science from University College Dublin, Ireland in 2024. My PhD supervisor was Assoc. Prof. Derek Greene from School of Computer Science, UCD. I was affiliated with the Insight Centre for Data Analytics during my PhD. While my earlier focus was on adhoc information retrieval, my PhD research aimed to exploring causality-driven IR, where I pursued 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.

    • Curriculum Vitae

    I finished both my bachelor's and master's from Maulana Abul Kalam Azad University of Technology, West Bengal, India, respectively in the year of 2013 and 2016. After that I worked in a research project at Indian Statistical Institute, Kolkata, India from 2016 to 2018. Then I served as an Assistant Professor at Techno India University, Kolkata, India and Xcelerator from 2018 to 2020. I started my PhD after that in the year of 2020 in Computer Science with the School of Computer Science in University College Dublin, Ireland and finished in 2024. Presently, I am working as a Post Doctoral Researcher at Insight Centre for Data Analytics in UCD, working with the Victeur team as part of the UCD Centre for Cultural Analytics.
